Ikester makes good points. The issue of evolutionist dating techniques really seems to deserve its own thread.

It seems to me that a little creationism is present even in the most atheistic versions of evolutionism. If rocks are created at certain various dates, what else can it mean? We see the creation of rocks acknowledged, but yet credit is never given to anyone for the event.

I find this state of affairs somewhat amusing. Of course I don't want to laughroll prematurely.

I already answered this in that thread but I'll re-post here.

I would suggest that anyone wishing to discuss dating methods, first learn a little about that which you are discussing. Wiki is a good starting point. It would make for a better discussion if all parties knew something about how scientists date rocks and fossils.

Post as follows:

Hi Ikester,

Quote

Radiometric dating of igenous rock dates the time at which is cooled and crystallised. Cosmogenic dating dates the amount of exposure to cosmic rays that rock or ice has undergone, in effect dating the amount of time the surface has been exposed. Those are two I know off the top of my head. The uranium dating in the Grand Canyon discussions is also a way of doing this.

Quote

Current theory is that a planet-sized object smashed into the earth very early in its history, during what we call the era of heavy bombardment. The fragments of the moon came together to form the moon billions of years ago. So it is more or less the same age of the earth, as radiometric dating of moon rocks tells us.

Quote
Is there such a thing as cross contamination in age dating? Yes there is. What this means is that if a fossil, that dates a few thousand year old, is buried in a geological layer that dates a millions years old. Given time the layer will cross contaminate the fossil to date the same age as the layer does. This is why layers date the fossils, and fossils date the layers so well.


The radiometric dating methods of rocks are not used on fossils. If we are doubtful about the age of a fossil, and whether or not it has been found in situ (as opposed to having been washed there from elsewhere, for example), there are various methods that can be employed. It can be compared with index fossils present in the same rock. A fluorine analysis can also be done:

Quote
When bones, teeth, or antlers are found at a site, fluorine analysis can be used to tell us whether or not the animals they were from actually lived at about the same time. This relative dating method is based on the fact that there are specific progressive chemical changes in skeletal remains that result from burial underground. As time passes, the organic components of bone (mostly fats and proteins) are lost primarily through bacterial action. Since these components contain nitrogen, there is a progressive loss of that element. At the same time, percolating ground water deposits trace amounts of fluorine and other elements, such as uranium, into the bone. As a result, the amount of fluorine progressively increases. If the bones of two animals are buried at the same time in the same site, they should have about the same amount of nitrogen and fluorine. If they do not, they most likely come from different eras, despite the fact that they were found in association with each other.


Again, these are just the ones I know off the top of my head. I am not a scientist and I'm sure there are others. If you have a specific example here that you would like to discuss, please let me know.

Well, right out of the gate this one's a loser. I see two assumptions that cannot be verified: both specimens exposed to same amount of bacteria & same exposure to groundwater.

The assumption of uniform groundwater exposure runs contrary to observations you can make in your own yard (or any nearby park if you lack a yard). Plants grow faster or slower based almost entirely on the amount of water they receive. Grass, trees, flowers, all plants are observed to grow at non-uniform rates due to one getting more water than its neighbor.

This fact also throws a monkey wrench into tree ring dating, but that's not a high priority for me these days.

First I'd like to draw attention here to Post 39418, which gives more information about radiometric dating. The problem is that since you started this thread with a post that already existed in another thread, we have parallel discussions happening.

Quote
I see two assumptions that cannot be verified: both specimens exposed to same amount of bacteria & same exposure to groundwater.


If you had looked at the site I linked to, it says:

Quote
Fluorine analysis can be used only as a relative dating method because the rate of decay and the amount of dissolved minerals in the ground water varies from site to site. In other words, the biochemical clock that this method relies on runs at a different rate in different environments. Fluorine analysis is primarily used for verifying whether or not two fossils in the same strata at a site were in fact contemporaneous. If not, then at least one of them must be physically out of context.


The original question was:

Quote
a fossil, that dates a few thousand year old, is buried in a geological layer that dates a millions years old.


If a fossil appears not to be in situ, then fluorine dating can help determine that. Archaeologists can also look at other fossils existing in the same stratum of rock, which could possibly extend for miles. Taking samples from different parts of that stratum can help determine whether some of those fossils have younger ages. And as I said, we know the evolutionary history of some fossils so well (such as foraminifera) that they can be used as index fossils to help date other fossils found with them.

Actually I'm not quite sure what your specific question is here . . . ?

I wasn't making that comment as a personal attack, especially since you're not engaged in the active debate here. I meant it for anyone who posts comments about things like dating methods without reading up on what they actually are, how scientists use them, and what results they produce. I think it's a reasonable enough request to ask them to do that.

Linda - I think everyone on here (of faith) has established that nothing WE say will be seen as evidence.... So I'm approaching from a different point of view..... One that I know. I have a tape on the differences of the dating methods. I have no interest in researching it in depth, but when I find that I'll give it a look to try and post on that.

Your arrogance yesterday offended me Linda. You are my dear, a cranky person. And right now so am I.

Sorry for the display of anger above. I have a fever and am so miserable I have no level of tolerance for any sarcasm or inuendo at this point. I am not full out sick very often (although never feel well) and am not very patient when I am.

I'm sorry Linda....

They're talking about the mineral content of the water. I'm talking about the water itself. Water isn't distributed evenly underground. Even an inch or two can make a huge difference.

Quote
Archaeologists can also look at other fossils existing in the same stratum of rock, which could possibly extend for miles.
Yep. And water exposure is assumed to be the same when anyone can look at practically any patch of grass and see this is a false assumption.

Quote
And as I said, we know the evolutionary history of some fossils so well (such as foraminifera) that they can be used as index fossils to help date other fossils found with them.
But not all are privy to revelations from the evogods, and those who aren't face a choice: reason in circles, or decline to reason in circles. You absolutely must assume evolutionism is truth before you can imagine the existence of an "index fossil".

For purposes of verification, it's obvious neither flourine evodates or index fossil evodates are remotely close to sufficient.

The logical fallacy first, CTD:

Quote
We see the creation of rocks acknowledged, but yet credit is never given to anyone for the event.
This is the logical fallacy of equivocation, where "creation" is used to mean formation, and then it is taken to have meant specieal biblical creation.

We see rocks made today with no need to acknowledge any special handling of material. You can actually do it in a lab. Ever made crystals? Ever seen a "commercial diamond"?

We also see new rocks formed from lava at every volcano.

These are not bits of special creation, as far as I know.

The Devil's Hole and Radiometric Age

To discuss radioactive decay and dating systems that are based on this concept we need a system that can be correlated over substantial time to validate the system.

http://water.usgs.gov/nrp/devilshole.html

Quote
Devils Hole is a tectonically-formed subaqueous cavern in south-central Nevada. Vein calcite, which coats the walls of this cavern, has provided an extremely well-dated 500,000-year record of variations in temperature as well as other paleoclimatic parameters.
We have correlations between age, climate and temperatures, so how is this data evaluated?

Devils Hole is a tectonically formed cave developed in the discharge zone of a regional aquifer in south-central Nevada. (See Riggs, et al., 1994.) The walls of this subaqueous cavern are coated with dense vein calcite which provides an ideal material for precise uranium-series dating via thermal ionization mass spectrometry (TIMS). Devils Hole Core DH-11 is a 36-cm-long core of vein calcite from which we obtained an approximately 500,000-year-long continuous record of paleotemperature and other climatic proxies. Data from this core were recently used by Winograd and others (1997) to discuss the length and stability of the last four interglaciations.

Carbon and oxygen stable isotopic ratios were measured on 285 samples cut at regular intervals inward from the free face of the core (as reported in Winograd et al. ,1992, and in Coplen et al., 1994). Table 1 lists only 284 samples because a sample taken at 114.28 mm was eliminated when post-1994 reanalysis of its delta 18O value indicated an error in the earlier determination. Carbon isotopic ratios are reported in per mill (footnote #1) relative to VPDB, defined by assigning a delta 13C of +1.95 per mill to the reference material NBS 19 calcite. Oxygen isotopic ratios are reported relative to VSMOW reference water on a scale normalized such that SLAP reference water is -55.5 per mill relative to VSMOW reference water. The oxygen isotopic fractionation factors employed in this determination are those listed in Coplen and others (1983). The delta 18O value of the isotopic reference material NBS 19 on this scale is +28.65 per mill. The ± 1 sd (standard deviation) error for the delta 18O and delta 13C analyses is ±0.07 and 0.05 per mill, respectively.


They measured the age with a radiometric decay system and also measured d18O and d13C as measures of climate. There is a table with the 284 samples by age with d18O and d13C values. For a correlation of that data to the age and climate information from another source we can compare the isotope ratios to those found in the antarctic ice cores:

The Devils Hole d18O record is an indicator of paleotemperature and corresponds in timing and magnitude to paleo-SST (sea surface temperature) recorded in Pacific Ocean sediments off the California and Oregon coasts. The record is also highly correlated with major variations in temperature in the Vostok ice core, from the East Antarctic plateau. The d13C record is thought to reflect changes in global variations in the ratio of stable carbon isotopes of atmospheric CO2 and/or changes in the density of vegetation in the groundwater recharge areas tributary to Devils Hole.
(See Winograd et al., 1996; Herbert et al., 2001; Winograd, 2002; Winograd, et al., 1997; Landwehr and Winograd, 2001; Landwehr, 2002; and Coplen, et al., 1994.)

As eminent a geochemist as W. Broecker has stated that "...the Devils Hole chronology is the best we have..." Since 1992, all core material has been uranium-series dated using thermal ionization mass spectrometric (TIMS) methodology. In 1997, the Devils Hole Thorium-230 dates were independently confirmed by non-USGS investigators using Protactinium-231.
(See Broecker, 1992; Ludwig, et al., 1992; Winograd, et al., 1997; and Edwards, et al., 1997.)


The correlations with actual age from the ice layers in Greenland and Antarctica can be covered later, for now we just note that the isotope ratios are "highly correlated" with those layers for the same ages derived by these radiometric methods.

So what exactly do we have here? Water dripping down a cave wall, depositing calcite and various other minerals and impurities, elements that are soluble in water, including trace levels of radioactive isotopes of uranium. Material that gets deposited as the water evaporates, forming layer after layer of similar deposits, each one trapping the material in their respective layers. The calcite forms a matrix that holds the impurities, minerals and trace elements in a position related to the time the calcite was deposited.

http://en.wikipedia.org/wiki/Calcite

Quote
The carbonate mineral calcite is a chemical or biochemical calcium carbonate corresponding to the formula CaCO3 and is one of the most widely distributed minerals on the Earth's surface. It is a common constituent of sedimentary rocks, limestone in particular. It is also the primary mineral in metamorphic marble. It also occurs as a vein mineral in deposits from hot springs, and also occurs in caverns as stalactites and stalagmites. Calcite is often the primary constituent of the shells of marine organisms, e.g., plankton (such as coccoliths and planktic foraminifera), the hard parts of red algae, some sponges, brachiopoda, echinoderms, most bryozoa, and parts of the shells of some bivalves, such as oysters and rudists). Calcite represents the stable form of calcium carbonate; aragonite will change to calcite at 470°C.


Radioactive elements decay into other elements, and some of these are not soluble, and thus the presence of these insoluble daughter elements is evidence of decay of the soluble parent elements. These daughter elements are still trapped in the layers of calcite that the parent elements were depositied in, so their position also relates to the age of the daughter elements in the calcite layers. We are interested in four isotopes of these matrix constrained elements, two radoactive - thorium-230 and protactinium-231 - and two not radioactive - oxygen-18 and carbon-13 - and what they can tell us about climate and age.

Thorium-230

http://www.asa3.org/ASA/resources/Wiens.html

Quote
Two of the most frequently-used of these "uranium-series" systems are uranium-234 and thorium-230.

Like carbon-14, the shorter-lived uranium-series isotopes are constantly being replenished, in this case, by decaying uranium-238 supplied to the Earth during its original creation. Following the example of carbon-14, you may guess that one way to use these isotopes for dating is to remove them from their source of replenishment. This starts the dating clock. In carbon-14 this happens when a living thing (like a tree) dies and no longer takes in carbon-14 laden CO2. For the shorter-lived uranium-series radionuclides, there needs to be a physical removal from uranium. The chemistry of uranium and thorium are such that they are in fact easily removed from each other. Uranium tends to stay dissolved in water, but thorium is insoluble in water. So a number of applications of the thorium-230 method are based on this chemical partition between uranium and thorium.

On the other hand, calcium carbonates produced biologically (such as in corals, shells, teeth, and bones) take in small amounts of uranium, but essentially no thorium (because of its much lower concentrations in the water). This allows the dating of these materials by their lack of thorium. A brand-new coral reef will have essentially no thorium-230. As it ages, some of its uranium decays to thorium-230. While the thorium-230 itself is radioactive, this can be corrected for. The equations are more complex than for the simple systems described earlier, but the uranium-234 / thorium-230 method has been used to date corals now for several decades. Comparison of uranium-234 ages with ages obtained by counting annual growth bands of corals proves that the technique is highly accurate when properly used (Edwards et al., Earth Planet. Sci. Lett. 90, 371, 1988). The method has also been used to date stalactites and stalagmites from caves, already mentioned in connection with long-term calibration of the radiocarbon method. In fact, tens of thousands of uranium-series dates have been performed on cave formations around the world.

As with all dating, the agreement of two or more methods is highly recommended for confirmation of a measurement.


At the Devil's Hole we are essentially dealing with one very large stalactite. The calcite was deposited after being dissolved in water, the Th-230 in the calcite could only come from the decay of the parent U-234, giving an accurate measurement of the age of the layers of calcite.

See also http://en.wikipedia.org/wiki/Thorium(7). Thorium-230 has a half-life of 75,380 years.

Protactinium-231

http://www.ead.anl.gov/pub/doc/protactinium.pdf

Quote
Protactinium is a malleable, shiny, silver-gray radioactive metal that does not tarnish rapidly in air. It has a density greater than that of lead and occurs in nature in very low concentrations as a decay product of uranium. There are three naturally occurring isotopes, with protactinium-231 being the most abundant. ... The other two naturally occurring isotopes are protactinium-234 and protactinium-234m (the “m” meaning metastable), both of which have very short half-lives (6.7 hours and 1.2 minutes, respectively) and occur in extremely low concentrations.

Protactinium-231 is a decay product of uranium-235 and is present at sites that processed uranium ores and associated wastes. This isotope decays by emitting an alpha particle with a half-life of 33,000 years to actinium-227, which has a half-life of 22 years and decays by emitting an alpha or beta particle.

Protactinium is widely distributed in very small amounts in the earth’s crust, and it is one of the rarest and most expensive naturally occurring elements. It is present in uranium ores at a concentration of about 1 part protactinium to 3 million parts uranium. Of the three naturally occurring isotopes, protactinium-231 is a decay product of uranium-235, and protactinium-234 and protactinium-234m are decay products of uranium-238.


The U-235 to Pa-231 decay is from a different series than the U-234 to Th-230 decay, so the two are independent of each other. Again, as the Devil's Hole calcite was deposited after being dissolved in water, the Pa-231 in the calcite could only come from the decay of the parent U-235, giving an accurate measurement of the age of the layers of calcite.

See also http://en.wikipedia.org/wiki/Protactinium(6). Protactinium-231 has a half-life of 32,760 years.

Radioactive Decay

The radiation decay curve is exponential, with different results for different decay constants - the half-lives of the radioactive isotopes.

http://en.wikipedia.org/wiki/Exponential_decay

Quote
A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. Symbolically, this can be expressed as the following differential equation, where N is the quantity and λ is a positive number called the decay constant:
N(t) = N(0)e^-λt

Here N(t) is the quantity at time t, and N(0) is the (initial) quantity, at time t=0.

If the decaying quantity is the number of discrete elements of a set, it is possible to compute the average length of time for which an element remains in the set. This is called the mean lifetime, and it can be shown that it relates to the decay rate,
T = 1/λ

The mean lifetime (also called the exponential time constant) is thus seen to be a simple "scaling time"

A more intuitive characteristic of exponential decay for many people is the time required for the decaying quantity to fall to one half of its initial value. This time is called the half-life, and often denoted by the symbol t(1/2). The half-life can be written in terms of the decay constant, or the mean lifetime, as:
t(1/2) = ln2/λ = Tln2

When this expression is inserted for T in the exponential equation above, and ln2 is absorbed into the base, this equation becomes:
N(t) = N(0)2^-t/t(1/2)


Using the half-lives of thorium-230 (75,380 years) and protactinium-231 (32,760 years), we can now draw the exponential curves for these isotopes (with % on the y-axis and time in k-yrs on the x axis, thorium in blue and protactinium in red):

[Linked Image]


This means we have a series of data with three different pieces of information: calcite layer (relative) age, Thorium-230 content and Protactinium-231 content. We also note that Thorium-230 has a half-life of 75,380 years, while Protactinium-231 has a half-life of 32,760 years - less than half the half-life of Thorium-230. This means that layer by layer the ratio of Thorium-230 to Protactinium-231 is different:


Age ... THr=THf/THo .. PAr=PAf/PAo .. THr/PAr
---------------------------------------------------
..75,380 ... 0.5000 ..... 0.2029 ....... 2.46 .
.150,760 ... 0.2500 ..... 0.0412 ....... 6.07 .
.226,140 ... 0.1250 ..... 0.0084 ...... 14.96 .
.301,520 ... 0.0625 ..... 0.0017 ...... 36.86 .
.376,900 ... 0.0313 ..... 0.0003 ...... 90.82 .
.452,280 ... 0.0156 ..... 0.0001 ..... 223.77 .
.527,660 ... 0.0078 ..... 0.00001 .... 551.35 .

So for these dates to be invalid there would have to be a mechanism that can layer by layer preferentially change the ratio of these two {elements\isotopes} within the solid calcite vein, and if you change the rate of decay then you need to change the rate of deposition of the calcite exponentially to match thickness for apparent age.

Conclusions

Based on this information alone we can conclude:
  • The theoretical basis for radiometric dating is accurate and valid.
  • The two different radiometric methods are equally valid - at least as far back as 567,700 yr BP.
  • That there was no change in the behavior of radioactive materials in the last 567,700 years, and
  • The world is older than 567,000 years and no global flood has occurred in that time.

Ikester makes good points. The issue of evolutionist dating techniques really seems to deserve its own thread.
We can discuss the correlations of the different methods of dating and at the same time answer some of ikester's questions,

A Further Discussion of Radiometric Correlations

There are correlations between radiometric dating methods, all showing broad consistency in results when properly applied:

http://www.asa3.org/ASA/resources/Wiens.html

Quote
  • There are well over forty different radiometric dating methods, and scores of other methods such as tree rings and ice cores.
  • All of the different dating methods agree--they agree a great majority of the time over millions of years of time. Some Christians make it sound like there is a lot of disagreement, but this is not the case. The disagreement in values needed to support the position of young-Earth proponents would require differences in age measured by orders of magnitude (e.g., factors of 10,000, 100,000, a million, or more). The differences actually found in the scientific literature are usually close to the margin of error, usually a few percent, not orders of magnitude!


Let's look at some of those numbers:

http://www.don-lindsay-archive.org/creation/confirm.html

Quote
However, there is an easier way to check if a method is reliable. We can see if it gives consistent answers against some other method.For example, Potassium-Argon (K-Ar) dating was tested against the Cenozoic-Era North American Land Mammal ordering. By ordering, I mean that rock layers were given numbers, with bigger numbers at greater depth. Each fossil was given the number of the rock layer it was found in. (Geologists call this stratigraphic order.) Here are the results:

Stratigraphic ................. K-Ar Date .. # Samples
Position ..... Name of Age .. (millions) ... Dated
=============================================
...1 ......... Irvingtonian ....... 1.36 ........... 1
...2 ......... Blancan ............ 1.5 - 3.5 ....... 7
...3 ......... Hemphillian ....... 4.1 -10.0 ...... 8
...4 ......... Claredonian ....... 8.9 -11.7 ..... 16
...5 ......... Barstovian ....... 12.3-15.6 ....... 9
...6 ......... Hemingfordian .. 17.1 ............. 1
...7 ......... Arikareean ....... 21.3-25.6 ...... 4
...8 ......... Orellian ............ --- ............. 0
...9 ......... Chadronian ....... 31.6-37.5 ..... 9
..10 ......... Duchesnean ...... 37.5 ........... 3
..11 ......... Uintan ............ 42.7-45.0 ..... 2
..12 ......... Bridgerian ........ 45.4-49.0 ..... 2
..13 ......... Wasatchian ....... 49.2 ........... 1
..14 ......... Puercan ........... 64.8 ........... 1

The standard geological idea is that "deeper is older". (It's called the Principle of Superposition, and was invented two centuries before Darwin.) In this table, Superposition and K-Ar dating are mutually consistent.
Layer by layer the stratigraphic measures older by radiometric dating, entirely consistent with the long term deposition of sedimentary layers. None of the K-Ar Dates overlap into the wrong sedimentary layers. This is similar to the layer by layer correlation between Thorium-230 content and Protactinium-231 with the calcite layers in Devil's Hole.There is also one layer that is not measured - the Orellian - and here is dated by the "sandwich" method (layers above and below) to 25.6 to 31.6 million years ago (this essentially makes a prediction that dating will fill this gap within this range). This demonstrates how this type of dating of objects works.

One of the most exciting and important scientific findings in decades was the 1980 discovery that a large asteroid, about 10 kilometers diameter, struck the earth at the end of the Cretaceous Period. The collision threw many tons of debris into the atmosphere and possibly led to the extinction of the dinosaurs and many other life forms. The fallout from this enormous impact, including shocked quartz and high concentrations of the element iridium, has been found in sedimentary rocks at more than 100 locations worldwide at the precise stratigraphic location of the Cretaceous-Tertiary (K-T) boundary (Alvarez and Asaro 1990; Alvarez 1998). We now know that the impact site is located on the Yucatan Peninsula. Measuring the age of this impact event independently of the stratigraphic evidence is an obvious test for radiometric methods, and a number of scientists in laboratories around the world set to work.

In addition to shocked quartz grains and high concentrations of iridium, the K-T impact produced tektites, which are small glass spherules that form from rock that is instantaneously melted by a large impact. ... The results from all of the laboratories were remarkably consistent with the measured ages ranging only from 64.4 to 65.1 Ma (Table 2). Similar tektites were also found in Mexico, and the Berkeley lab found that they were the same age as the Haiti tektites. But the story doesn’t end there.The K-T boundary is recorded in numerous sedimentary beds around the world. The Z-coal, the Ferris coal, and the Nevis coal in Montana and Saskatchewan all occur immediately above the K-T boundary. Numerous thin beds of volcanic ash occur within these coals just centimeters above the K-T boundary, and some of these ash beds contain minerals that can be dated radiometrically. Ash beds from each of these coals have been dated by 40Ar/39Ar, K-Ar, Rb-Sr, and U-Pb methods in several laboratories in the US and Canada. Since both the ash beds and the tektites occur either at or very near the K-T boundary, as determined by diagnostic fossils, the tektites and the ash beds should be very nearly the same age, and they are (Table 2).

[Linked Image]


There are several important things to note about these results. First, the Cretaceous and Tertiary periods were defined by geologists in the early 1800s. The boundary between these periods (the K-T boundary) is marked by an abrupt change in fossils found in sedimentary rocks worldwide. Its exact location in the stratigraphic column at any locality has nothing to do with radiometric dating — it is located by careful study of the fossils and the rocks that contain them, and nothing more. Second, the radiometric age measurements, 187 of them, were made on 3 different minerals and on glass by 3 distinctly different dating methods (K-Ar and 40Ar/39Ar are technical variations that use the same parent-daughter decay scheme), each involving different elements with different half-lives. Furthermore, the dating was done in 6 different laboratories and the materials were collected from 5 different locations in the Western Hemisphere. And yet the results are the same within analytical error. If radiometric dating didn’t work then such beautifully consistent results would not be possible.
(Note image used is originally from this website and was only copied to a mirror site to reduce bandwidth traffic on the original source).

That's 187 results between minimum 63.1 million years ago and maximum 66.5 million years ago, from a number of different sources and techniques.

Here's another correlation:

http://www.don-lindsay-archive.org/creation/crater_chain.html

Quote
To check, we need one single event which has been dated by several methods. A nice example is the Triassic multiple-impact event, which formed a 4500-kilometer-long chain of huge craters. (There must have been a train of big objects from space, which hit the spinning earth, one by one, across several hours. Much like the way comet Shoemaker-Levy hit Jupiter in 1994.)

Here are the five confirmed craters:

.. Crater ..... Country ... Diameter ... 10^6 yrBP ... Dating Method
------------------------------------------------------------------------------------
Manicouagan ... Canada ..... 100 km ..... 214 ± 1 .... U-Pb on zircons
Saint Martin .... Canada ...... 40 km ..... 219 ± 32 ... Rb/Sr
Rochechouart ... France ...... 25 km ..... 214 ± 8 .... Ar/Ar laser spot fusion
Obolon ........... Ukraine ..... 15 km ..... 215 ± 25 ... stratigraphic
Red Wing ........ USA .......... 9 km ..... 200 ± 25 ... stratigraphic

"Stratigraphic" dating means that the crater itself has not been dated. Instead, the rock strata above and below the crater was dated. (By now, the Red Wing crater is under 1.5 kilometers of sediment.)
All of those ages overlap within the margins of error for each method - an actual age of 214x10^6 years BP is consistent with each one.

Some meteorites, because of their mineralogy, can be dated by more than one radiometric dating technique, which provides scientists with a powerful check of the validity of the results. The results from three meteorites are shown in Table 1. Many more, plus a discussion of the different types of meteorites and their origins, can be found in Dalrymple (1991).

[Linked Image]


There are 3 important things to know about the ages in Table 1. The first is that each meteorite was dated by more than one laboratory — Allende by 2 laboratories, Guarena by 2 laboratories, and St Severin by four laboratories. This pretty much eliminates any significant laboratory biases or any major analytical mistakes. The second thing is that some of the results have been repeated using the same technique, which is another check against analytical errors. The third is that all three meteorites were dated by more than one method — two methods each for Allende and Guarena, and four methods for St Severin. This is extremely powerful verification of the validity of both the theory and practice of radiometric dating.

In the case of St Severin, for example, we have 4 different natural clocks (actually 5, for the Pb-Pb method involves 2 different radioactive uranium isotopes), each running at a different rate and each using elements that respond to chemical and physical conditions in much different ways. And yet, they all give the same result to within a few percent. Is this a remarkable coincidence? Scientists have concluded that it is not; it is instead a consequence of the fact that radiometric dating actually works and works quite well. Creationists who wants to dispute the conclusion that primitive meteorites, and therefore the solar system, are about 4.5 Ga old certainly have their work cut out for them!
(Note image used is originally from this website and was only copied to a mirror site to reduce bandwidth traffic on the original source).

Excluding the Sm-Nd isochron (4 points) dating of St. Severin meteor - which runs from 4.22 billion years ago to 4.88 billion years ago - that's 16 results between 4.34 billion years ago and 4.61 billion years ago (and also within the envelope of the St. Severin meteor

Notice that these correlated dates all imply an age for the earth of ~4.5 billion years. This is one piece of evidence of the extreme old age of the earth.

http://www.asa3.org/ASA/resources/Wiens.html

Quote
Most of the rocks we have from the moon do not exceed 4.1 billion years. The samples thought to be the oldest are highly pulverized and difficult to date, though there are a few dates extending all the way to 4.4 to 4.5 billion years. Most scientists think that all the bodies in the solar system were created at about the same time. Evidence from the uranium, thorium, and lead isotopes links the Earth's age with that of the meteorites. This would make the Earth 4.5-4.6 billion years old.


Matching data on the earth, on the moon and from meteors.

The essential element of measuring the age of the earth is NOT finding evidence that the earth is young - that is easy on an old earth - but in finding the oldest available evidence - evidence of age that just cannot be made compatible with any young earth creation model no matter how hard the creationists try.

Note: The age of the earth ~4.5 billion years based on this data.

Bottom line: to say that the methods are "inaccurate" is true - there are margins of error in every measurement system known to man (nothing is "accurate"), but to imply that they are unreliable is false, the amount of error is not enough to make the earth young.

For comments related to common creationist arguments against radioactive dating techniques see Chris Stassen's comments at:

Enjoy.

ps - thanks for starting a thread where we can deal with the issues of the age of the earth, radiometric, tree ring, lake suigetsu varves, there is so much information out there that shows the earth is in fact old.

These are not bits of special creation, as far as I know.
If they were, it wouldn't be very biblical. Ongoing acts of creation just don't match what is written. These Concepts are an artifact of earlier atheism & earlier compromise.

It's common knowledge that when dates come out "wrong" (as if they know) this is often attributed to the rock having "older" contents. Now all rocks, when they form, are formed from matter that was already around. So saying a rock was "formed from older matter" would be self-evident and redundant. The excuse implies a creation event of some sort. It implies that some things are not formed from older matter.

The Devil's Hole and Radiometric Age

To discuss radioactive decay and dating systems that are based on this concept we need a system that can be correlated over substantial time to validate the system.
It may have escaped your notice, but 'substantial' is the opposite of 'imaginary'.

Correlation, far from validating evodates, merely helps one maintain that they don't invalidate themselves. How much correlation should exist and how universal it should or shouldn't be are largely subjective matters - unless one wants to get strictly scientific about it. A single exception is all that's required to invalidate an hypothesis, under strict science.

Quote
They measured the age with a radiometric decay system...
Misleading. They measure physical qualities, apply assumptions, and conclude age.

Quote
The correlations with actual age from the ice layers in Greenland and Antarctica can be covered later, for now we just note that the isotope ratios are "highly correlated" with those layers for the same ages derived by these radiometric methods.
'Highly correlated' isn't the same as 'perfectly correlated'. Are there discrepancies? How many discrepancies are required to disqualify an hypothesis?



Quote
Radioactive elements decay into other elements, and some of these are not soluble,
Oh I should like to challenge that statement. I've looked into similar claims in the past & found them false. Please name your best candidate for an element which isn't soluble. I don't intend to play spam games, so if you provide a list, I will choose one myself.

I see your source doesn't tell a straight story.

As with all dating, the agreement of two or more methods is highly recommended for confirmation of a measurement.
I guess they could mean 'relatively insoluble' rather than 'absolutely insoluble'...

Radioactive Decay

The radiation decay curve is exponential, with different results for different decay constants - the half-lives of the radioactive isotopes.
Yes, the curve is exponential, and it's not hard to play tricks with the math. One could calculate 1/4 lives, 1/3 lives, or 1/277 lives for decaying elements. All will result in different exponential curves.

All are abstractions based upon the (calculated) chance of a given atom decaying in a given timeframe. One could directly calculate the number of atoms involved and directly apply probabilities to the result without ever employing the 1/2 life abstraction.

I haven't dug into the history of this convention, but I have little confidence in it.

The wikisource glosses over this, claiming the halflife method is "more intuitive". Just compare the formulas to see which is simple & intuitive and which adds complexity.

Quote
Based on this information alone we can conclude:
  • The theoretical basis for radiometric dating is accurate and valid.
  • The two different radiometric methods are equally valid - at least as far back as 567,700 yr BP.
  • That there was no change in the behavior of radioactive materials in the last 567,700 years, and
  • The world is older than 567,000 years and no global flood has occurred in that time.


Enjoy.
Come now, I think we all know the basis of your conclusions.

Post is long & time is short. I intend to get around to more. LindaLou's first in line, so I'll be taking that into consideration.

They're talking about the mineral content of the water. I'm talking about the water itself. Water isn't distributed evenly underground. Even an inch or two can make a huge difference.


I don't understand what you are saying. Buried bones take up fluorine from surrounding soils. The amount of fluorine taken up is proportional to the amount in the surrounding deposit and the length of time the bone has been buried. Varying concentrations of fluorine in different deposits preclude the method from being considered absolute, but it can be used to measure the relative ages of bones found in the same deposit.

Are you saying that geologists don't know how to measure fluorine amounts in the surrounding soil? Or what, exactly?

Quote
But not all are privy to revelations from the evogods, and those who aren't face a choice: reason in circles, or decline to reason in circles. You absolutely must assume evolutionism is truth before you can imagine the existence of an "index fossil".

For purposes of verification, it's obvious neither flourine evodates or index fossil evodates are remotely close to sufficient.


Yet strangely, you have given no evidence for why you do not "believe in" index fossils, nor is there any inidcation that you looked at the link I provided which gives evidence for millions of years of foraminifera evolution, unbroken throughout the fossil record. These kinds of fossils are found so reliably in specific layers around the world that they can give information about the age of other fossils found with them. Regardless of water or fluorine.

By now you will of course be aware that personal refusal to accept evidence has no bearing on the evidence itself.

No. I said nothing about biblical creation.
So then who would need to get credit?

Quote
If I did make crystals, would I get credit?
Do you need to? It's just chemical reactions.

Quote
If they were, it wouldn't be very biblical. Ongoing acts of creation just don't match what is written. These Concepts are an artifact of earlier atheism & earlier compromise.
So no one needs to give anyone credit when new rocks are formed. Thanks for clearing that up.

Quote
It's common knowledge that when dates come out "wrong" (as if they know) this is often attributed to the rock having "older" contents.
No, it's common creationist assertion and some documented misuse of dating methods. Any method can be misused, so when the results of such misuse are used to disprove the method all it shows is (a) that the person doing it intentionally misused the method, and (b) pretends that it isn't misused to (c) delude gullible people that don't know better.

Quote
Now all rocks, when they form, are formed from matter that was already around. So saying a rock was "formed from older matter" would be self-evident and redundant. The excuse implies a creation event of some sort. It implies that some things are not formed from older matter.
True, and if you read the actual literature about the physical and chemical processes you will see that what they are dating is the time of formation of the new rock from old matter by the physical and chemical changes that occur.

Congratulations, btw, as you just showed that the material that the earth is made up from is older than any of the radiometric dates for any object of evidence that has been dated.

Quote
It may have escaped your notice, but 'substantial' is the opposite of 'imaginary'.
Which says nothing about the substantial time that is covered by the evidence.

Quote
Correlation, far from validating evodates, merely helps one maintain that they don't invalidate themselves.
And if they are not invalidated then they are ... (what's the opposite of invalidated?)? The other thing that these correlations do is they invalidate the concept that the methods are wildly inaccurate, what they show is the range of errors in the systems, the tolerance of the measurements. Even with inaccuracies of 10% there is still plenty of evidence that the world is billions of years old.

Quote
Misleading. They measure physical qualities, apply assumptions, and conclude age.
They apply physics and chemistry as we know it today and they end up with consistently correlated dates at every layer, they correlate for depth in the calcite, the amount of thorium present and the amount of protactinium, and it just all happens to end up with the same age. Consistant, layer by layer by layer by layer.

Quote
'Highly correlated' isn't the same as 'perfectly correlated'. Are there discrepancies? How many discrepancies are required to disqualify an hypothesis?
"Highly correlated" is a relative term based on correlation factors.

http://torque.oncloud8.com/archives/000579.html
Quote
The term "highly correlated" is vague. When are two variables or to datasets considered highly correlated? Correlation is often computed using the product-moment correlation coefficient or, in some circles, Pearson's correlation coefficient. This measure outputs a value between -1 and 1, i.e., negatively correlated to positively correlated. That's fine and good, but what do you call 0.78? Thanks to Savannah State University for giving a citable reference on this issue:
  • "r" ranging from zero to about .20 may be regarded as indicating no or negligible correlation.
  • "r" ranging from about .20 to .40 may be regarded as indicating a low degree of correlation.
  • "r" ranging from about .40 to .60 may be regarded as indicating a moderate degree of correlation.
  • "r" ranging from about .60 to .80 may be regarded as indicating a marked degree of correlation.
  • "r" ranging from about .80 to 1.00 may be regarded as indicating high correlation [1].
Pretty arbitrary* huh?
You can probably find other sources on statistics, and then we can talk about what the "r" value is and how it is calculated ... we don't know whether they are talking 0.80 or 0.99 ...

and it really is just another added correlation to the correlations between layers of calcite, levels of thorium and levels of protactinium, from an entirely different source, but still showing substantially the same results.

If we assume it is 0.80 then -- as a worst case -- the age of the Devil's hole calcite is 567,700 +/-20% -- or from 454,160 to 681,240 years old -- still way older than any YEC model I am aware of.

Do you think there is anything that is absolutely insoluble in water? Certainly what they can do is measure the relative solubility of different elements etc.

http://en.wikipedia.org/wiki/Insoluble
Quote
In a solution, the solvent is generally a liquid, which can be a pure substance or a mixture.[4] The species that dissolves, the solute, can be a gas, another liquid, or a solid. Solubilities range widely, from infinitely soluble such as ethanol in water, to poorly soluble, such as silver chloride in water. The term insoluble is often applied to poorly soluble compounds, although in some cases insolubility means that a compound is very poorly soluble.
What we have here is an isotope that is very soluble decaying into one that is substantially less (a lot less) soluble, and thus you have deposition of the new isotope atoms on the substrate, where they get locked in place by the calcite.

Quote
Yes, the curve is exponential, and it's not hard to play tricks with the math. One could calculate 1/4 lives, 1/3 lives, or 1/277 lives for decaying elements. All will result in different exponential curves.
Sadly for you this is a totally false statement. Very simply, the "1/4 life" would be the time it takes for a sample to decay to the point where only 1/4 of the original amount is left. This would take the same time, and end up at the same concentration, as waiting for 2 half-lives of any isotope.

If you want, I can go through the math and prove it (this is math now).

Quote
All are abstractions based upon the (calculated) chance of a given atom decaying in a given timeframe. One could directly calculate the number of atoms involved and directly apply probabilities to the result without ever employing the 1/2 life abstraction.
Correct, and curiously you would still end up with the same time span for the ages of the calcite layers by thorium and identical ages for the calcite layers by protactinium.

Quote
I haven't dug into the history of this convention, but I have little confidence in it.
And, curiously, the entire universe is unperturbed by your lack of confidence. No radioactive atoms sit up waiting for you to approve their decay.

Quote
The wikisource glosses over this, claiming the halflife method is "more intuitive". Just compare the formulas to see which is simple & intuitive and which adds complexity.
Which is still irrelevant to the issue of calcite deposits and actual quantities of thorium and protactinium that all agree on the age vs depth correlation. You can use any of the formulas they give and you end up with the same results: 567,700 years.

This is pretty simple math. After the first 1/4 life, 3/4 remain. After the next 1/4 life, 9/16 remain. 9/16 ain't 1/2.

1/4 x 1 = 1/4 First ql

1/4 + 3/16 = 7/16 Total

So 2 quarterlives do not give the same result as one halflife. Other fractions will do this too. Care to see four 1/8 lives?

Do you not think that samples would be taken throughout the area in question, and measured? Do you think that if your comment above was a serious problem, that this dating method would be used at all? It is also one tool at a scientist's disposal, not the sole test that a scientist would rely on, as it gives relative dates rather than absolute. Biostratigraphy (i.e. comparing with other fossils, often index fossils, all of which are found in faunal succession) is a preferred method, as is the radiometric dating of surrounding rock.

I still don't understand what your point is about the "water itself" as opposed to the mineral content, which is the important factor here. Excuse my grievous ignorance and enlighten me please.

No it's not. From a dictionary

Quote
1. Physics The time required for half the nuclei in a sample of a specific isotopic species to undergo radioactive decay.

Therefore, a quarter life is the time it takes for 1/4 of the material to decay away.

Quote
This would take the same time, and end up at the same concentration, as waiting for 2 half-lives of any isotope. This is pretty simple math. After the first 1/4 life, 3/4 remain. After the next 1/4 life, 9/16 remain. 9/16 ain't 1/2.

1/4 x 1 = 1/4 First ql
1/4 x 3/4 = 3/16 Second ql
1/4 + 3/16 = 7/16 Total
-7/16 + 1 = 9/16 Result

So 2 quarterlives do not give the same result as one halflife. Other fractions will do this too. Care to see four 1/8 lives?

That only works on linear functions. Since this is an exponential decay, a quarter-life is not equal to half of a half-life. Quarter-life and half-life are measures of the time it takes for a certain amount of the substance to decay away (1/4 of the material in the first case and 1/2 of the material in the second case). Those radioactive decays have been observed to occur following this function:

N(t) = N(0)e^-?t

Where N(t) = The amount of material at a particular time
N(0) = The initial amount of material.
t = The time expended
? = the decay rate, which is differs between materials

So, for a 1/2 life: N(t)/N(0) = 1/2 = e^-?t(half)

You then solve for t(half) and get: t(half) = (-ln(1/2))/? = .693/?

for a 1/4 life: N(t)/N(0) = 3/4 = e^-?t(quarter)

You then solve for t and get:
t(quarter) = (-ln(3/4))/? = .288/?

So t(quarter)/t(half) = (.288/?)/(.693/?)

Solve for t(quarter):

t(quarter)= ((.288/?)/(.693/?))* t(half) =(.288/.693)*t(half)

t(quarter) = .415 * t(half)

.415 is less than .5 so two quarter-lives is less time than one half-life. Therefore two quarter-lives can leave 9/16 of the material while one half-life can only leave 1/2 of the material.

I hope this helps

Still trying CTD,

Quote

That would fit with the definition of valid as used in science. The logical conclusion drawn from the physical properties of radioactive elements is actually found in the evidence of actual radioactive decay. Thus the concept has been tested, and the results validate the conclusion.

Quote
The Theory of Skunk Funk looks to be unstoppable!
Just as unstoppable as the "theory" of invisible little pink unicorns, because they are not testable. Anyone can make up stuff, the difference between fantasy and science is testing and testing and testing the concepts for validity.

Quote
Ever notice that self-validation = circular reasoning, RAZD? If you have ever noticed this, please remind yourself.
Except we are not talking about self validation, we are talking about validating an intellectual concept with real physical objective evidence (the part where your "skunk funk" fails). It is evidence that validates (or invalidates) theoretical concepts.

Quote

And should I omit (as some do) to make this clear to others, who might mistake the term to be literal rather than relative? What purpose would that serve?
The difference is that one can recognize that we are talking orders of magnitude of difference in solubility, measured as the maximum density of the solute in the solution. 1 atom in a gallon is not what I would call soluble. When Wiens says "but essentially no thorium (because of its much lower concentrations in the water)" that would be because it is very insoluble. Meanwhile you may have floating particles with some thorium, caused by the same process, but those would not be consider dissolved in the water, while they would be available for marine organisms to ingest. You should be happy to see that scientists don't assume there is no thorium based on it being insoluble, but consider that there could be initial levels present.

This still does not address the issue that uranium is many times more soluble in water than thorium is, and that when uranium decays into thorium many of those atoms will then come out of solution and be deposited.

Quote

LinearAQ has already provided some information about why you are wrong here, and yes, it has to do with your using a linear interpolation rather than one based on the mathematical curve involved.

You can also compare this by simply to using two half lives as the original time frame: after the double half life you have 0.5x0.5 = 0.25% remaining.

Using your approach we now calculate the amount at half that time as (1+0.25)/2 = 0.625 = 62.5% ... but we know that at a single half life we have 50%, so you obviously have an error in your assumption, in this case of a linear correlation as opposed to an exponential one.

You can actually calculate your 1/4, 1/3 1/whatever lives (properly - see LinearAQ's post) and then plot the results and you will end up with exactly the same curve as you get with half-life.

Enjoy.

Please address your question about this to RAZD, when you are finished discussing the other points about radioactive decay.
This argument (Pratt Claim CF201) assumes there is no source of modern Polonium.

The problem for Creationists that use this example, though is to explain the existence of Uranium Halos:

From Dr Wiens:
Quote
13. "Radiation halos" in rocks prove that the Earth was young.

This refers to tiny halos of crystal damage surrounding spots where radioactive elements are concentrated in certain rocks. Halos thought to be from polonium, a short-lived element produced from the decay of uranium, have been found in some rocks. A plausible explanation for a halo from such a short-lived element is that these were not produced by an initial concentration of the radioactive element. Rather, as water seeped through cracks in the minerals, a chemical change caused newly-formed polonium to drop out of solution at a certain place and almost immediately decay there. A halo would build up over a long period of time even though the center of the halo never contained more than a few atoms of polonium at one time. "Hydrothermal" effects can act in ways that at first seem strange, such as the well-known fact that gold--a chemically un-reactive metal with very low solubilities--is concentrated along quartz veins by the action of water over long periods of time. Other researchers have found halos produced by an indirect radioactive decay effect called hole diffusion, which is an electrical effect in a crystal. These results suggest that the halos in question are not from short-lived isotopes after all.

At any rate, halos from uranium inclusions are far more common. Because of uranium's long half-lives, these halos take at least several hundred million years to form. Because of this, most people agree that halos provide compelling evidence for a very old Earth.
(bold mine for emPHAsis)

And this again comes back to the basic problem for all Young Earth scenarios: it is easy to find evidence of young things in an old earth, but how do you explain the evidence of old things in a young earth?

Enjoy.

RAZD: And this again comes back to the basic problem for all Young Earth scenarios: it is easy to find evidence of young things in an old earth, but how do you explain the evidence of old things in a young earth?

Jeanie: Because for even those who think the earth is young it was still created from already existing matter!

No it's not. From a dictionary

Therefore, a quarter life is the time it takes for 1/4 of the material to decay away.

is that you also can find this definition:

http://en.wikipedia.org/wiki/Halflife
Quote
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value.
And from this you would extrapolate a quarter-life to be the interval required for the quantity to decay to 1/4 of it's initial value. Perhaps the reason that half-life is used is that it works both ways with the same numbers, so you don't end up with confusion of which 1/4 you are talking about.

Curiously, it doesn't matter whether you define it as 1/4 or 3/4, as:

(1) you are still most emphatically, absolutely wrong, and

(2) you still end up with the same decay curve.
Nt = No(e^-λt)

λ is a constant, not dependent on time.

Many things in nature follow this pattern.

Hey Jeanie,

... the earth is young it was still created from already existing matter!
So you are saying that YE scenarios are entirely compatible with a 13.7 billion year old universe existing long before the formation of the earth from the debris of exploding stars?

I just want to be clear on your point.

Enjoy.

Suggest? The diameters of the halos are just the right size to be diagnostic of polonium, but that's "just a coincidence", eh?

While these lies are insulting and arrogant, it is amusing to see how low their quality is, and how low some will sink in order to obscure the truth.

You don't seem to be paying attention very well. The existence of these radiohalos isn't evidence that the Earth is any age. It is evidence that is only consistent with virtually instantaneous creation to the best of our knowledge. There is no known means of creating them by natural or artificial means. In spite of all the evidence & theory that says they shouldn't, they exist!

Want another laugh? If there were any possible way to manufacture the radiohalos, Dr. Gentry would have been accused of fraud. But everybody knows there's no way to make them. Absence of actions by parties with strong motives and a history of consistently performing said actions can also speak eloquently.

I'm not sure what YE people think exactly, but I believe in the creation as you know. I know my scenario is compatible with that. God and the universe are eternal.

Looks like I will have to wait for him since you won't address the parts of my post that corrected you.

It makes one think that you cannot refute the fact that I smashed your implication that radioactive decay curves are mathematically manipulated to match what evolutionists want. Of course that's not really fair on my part since I took advantage of your lack of knowledge concerning mathematics.

That was the cause of your mistake, right? I mean, your lack of skill in setting up a proper mathematic model of the real life situation even though you were already given the formula that modeled the behavior, right?

That has to be it, because otherwise that would mean you were purposely misrepresenting the mathematics model of radioactive decay in order to score points with those who don't know better.

I'm sure you would not violate your faith's high standards just to look like a winner on a web forum.

Correct that to say "no natural source of the Polonium" since YEC's claim that the Polonium was instantaneously created by God when He formed the Earth 6000 years ago. I guess that would be the "assumption".

Why do you consider it a diversion? The isotopes of Polonium in question are direct descendants in the chain of decay daughters from Uranium. You can't just dismiss it.

It is plausible if you realize that the Polonium is a daughter product of a chain of decay daughters that started with Uranium.

Check out this reference on page 2 for the U-238 decay chain.

You mean like the solubility of the Radon and Radium (Uranium decay daughters)in alkali water and the lesser solubility of Polonium (Radon decay daughter) in the same water? For those who don't know, solubility is a chemical characteristic. Going into solution (dissolving) and coming out of solution (precipitating) are "chemical changes".

Yet they exist in granites that have obviously formed after the Earth was made because those granites lie on top of sedimentary rock.

Why would geologists accuse Gentry of fraud if they can go out and find samples of the radio-halos themselves? Everyone can note that you are accusing geologists of an ongoing pattern of deception and false accusation.

Well guess again, because nobody has made this assumption either.

Acknowledging (as everyone who's looked into the issue has) that Polonium can be a result of decay does not alter anything. The halos in question are not produced by uranium - they're produced by polonium. Were there uranium present, it would also have left a telltale halo of its own when it decayed.

The evidence isn't consistent with uranium being present in the center of the halos. It is consistent with polonium.

Both of these false assertions of assumptions where none exist are arrogant insults to the intelligence of the readership. Perhaps you might pray to your evogod(s) that they really are too stupid to notice.

So you agree that Polonium occurs naturally, and thus can find it's way - as pointed out by several people - into the rocks where the halo's are formed.

Therefore Polonium halos in question are evidence of recent Polonium, but not of a young earth.

Which doesn't address the issue of halos where uranium IS at the center, and which have taken several hundred million years to form (due to the decay rate of Uranium vs Polonium).

Or are you going to argue a special pleading that this phenomena apply to Polonium halos but not to Uranium halos?

There are lots of things that occur naturally. Spring showers haven't been observed finding their way to the center of the sun.

Indeed, had polonium a motive, it still couldn't create the halos by the processes evolutionists describe. The problem with all migration scenarios is that the polonium must decay en route, unless there exists a means to prevent decay. If you know of such a means, I'd be interested to hear about it.

More likely, you mean to claim it suspended decay & accuse me of "arguing from incredulity" if I don't buy your story.

But folks, please consider carefully what these evolutionists are advocating! They imagine decay can be halted. If it can be halted for polonium, why not all other radioactive elements?

These same people openly assume decay rates are always constant, any time this assumption will help them produce evodates. Someone's story invalidates itself.

They also assume polonium has some desire to "find its way" to certain places and decay there. Sort of like the legend of the Elephants' Graveyard.

So? I never suggested it did. Why should I address this now? It's pretty trivial business to find the error. Those who desire to divert their attention to this bunk, well, that's their own business.

You haven't yet given a lick of evidence to support the assumption you claimed creationists were making, either. It was just more empty, hollow bunk. Spam away & let us see how many morons fall victim to your trickery. What's next? Apoloniogenesis?

And here it is, just as predicted. Be quick with the eyes. Now you see the pea....now you don't. Despite the fact that Uranium 238 DOES NOT decay directly to Polonium 218, Polonium 214 or Polonium 210, your sleight of hand man, CTD, will claim that the evolutionists said it does. This is also in complete contradiction to the reference that I supplied to him here

Since the Uranium decays to Thorium, then Radium, then Radon and all of those have 1/2 lives significantly longer than the Polonium isotopes it is entirely possible for the atoms to have migrated to the final resting place before becoming Polonium. So the Polonium did not have to "halt" its decay because the atoms were not Polonium when they were en route.

Quote
They also assume polonium has some desire to "find its way" to certain places and decay there. Sort of like the legend of the Elephants' Graveyard.

Another misrepresentation and distraction. CTD claims that geologists not only are unaware of mechanisms for mineral deposition (water, gas diffusion...etc) but also believe that elements are sentient. Of course he expects the audience to be stupid enough to lap up that foul swill and smile while doing so.

Utterly false. Whether or not I have repeated the hypotheses available in the links is a separate issue altogether. You even nested your own quote, but managed to forget its contents in the time it took you to compose your post.

There is no YEC claim that polonium cannot form naturally. It does not exist. It is not assumed or implied anywhere. The claim is pretty simple, and a kindergartener can understand the fallacy you attempt to convince people they should accept.

The implication of the evidence is clear, and there are creationists who won't hesitate to say "God made the polonium that produced the halos". But this is different from saying "God used separate acts of creation to continue making polonium." God has put laws in place which govern nature, and cause the other elements He created to decay. Sin may be involved too, but God is the ultimate creator of all that exists.

You attempt to confuse the polonium which is responsible for the halos with all polonium. Before you draw inspiration from RAZD, you might look at the quality of his own deceptions, especially the most recent attempts.

As I said, a kindergartener can understand that 'some' isn't 'all'. You might ask yourself why we have separate words for 'some' and 'all', and maybe do a little research if you intend to maintain 'some' actually is 'all'.

I was talking about the potential for you & RAZD's imaginary "creationist assumptions" to have any substance behind them. Will you now claim these are both the same thing?

This is also in complete contradiction to the reference that I supplied to him here

Since the Uranium decays to Thorium, then Radium, then Radon and all of those have 1/2 lives significantly longer than the Polonium isotopes it is entirely possible for the atoms to have migrated to the final resting place before becoming Polonium. So the Polonium did not have to "halt" its decay because the atoms were not Polonium when they were en route.
Then please explain which of the elements you are claiming can halt its decay at will, or at your convenience.

Of course, had, oh let's choose thorium... had thorium migrated to designated elephant graveyards, it would still have to decay before you'd have your polonium. The decay would produce halos, thorium halos. But Dr. Gentry found polonium halos. Your stories start out stupid, and go downhill.

hehehe

By the way my dear readership, he has chosen you as the mark. Now...where's the pea?
If by "pea", you refer to hypotheses or evidence, they are supplied by the links given in the other thread.

I would further urge folks who haven't done so to view the halo pics I posted in that thread. Fractures are visible in some, but they're not consistent with the migration fantasies. Talk about grasping at straws! An what's the purpose? Why do they risk their reputations by pushing such an obviously false fantasy? To maintain their myth that God wasn't involved with creation. Shows just how "compatible" evolutionism is with truth.

Not really: Radon is a gas and is capable of traveling within rock along the smallest paths known. When Radon decays into Polonium it is no longer a gas, and the rest of the decay pattern would be the same as for Polonium.

In addition, the decay from Radon to Polonium has almost exactly the same energy as one of the Polonium decay stages, and many times would produce a ring hard to distinquish from the later decay.

Here is an interesting paper by an amateur scientist that has looked at this issue: Evolution's Tiny Violences: The Po-...ientist Examines Pegmatitic Biotite Mica

Quote
The suggested decay chain for Polonium is as follows. (I have begun the chain at Radon-222, fifth in the series of alpha particle- emitting daughters of Uranium-238, both for brevity and for another reason which will shortly become clear.)

86 Rn 222 (86 protons, Radon, mass 222) decays in about four days to Polonium-218 with the emission of an alpha particle of 5,486,000 electron volts (5.486 MeV). (Please note this energy value.)

84 Po 218 (84 protons, Polonium, mass 218) decays, through two additional non-alpha-emitting (beta decay) steps involving Lead and Bismuth, over a total of about 45 minutes, to Polonium-214 with the emission of a 6.111 MeV alpha particle.

84 Po 214 (84 protons, Polonium, mass 214, arriving via Lead-214 (27 minutes) and Bismuth 214 (20 minutes)) decays through two additional (and time-consuming) steps taking about 21 years, to Polonium 210, with the emission of a 7.687 MeV alpha particle. This involves the immediate alpha decay (.000164 seconds) of the Po-214 nucleus to Lead 210, which has a half-life of 21 years, then via beta decay to Bismuth 210 with a 5 day half-life, and another beta decay to Po 210. (There is a small chance of the Bismuth 210 appearing in its isomeric form, which has a half-life of three million years.) This Polonium-214 alpha energy is the highest in the Uranium 238 decay chain, and consequently creates the largest, outermost, halo.

84 Po 210 (84 protons, Polonium, mass 210) decays with a half-life of 138 days directly to Lead 206 (stable), emitting an alpha particle of 5,305,000 electron-volts' energy. (Note the close similarity between this energy and that of the decay from Radon 222 to Polonium 218.)

82 Pb 206 (82 protons, Lead, mass 206). End of the line. Stable Lead. No further decay is possible.
[Linked Image]
Figure 1. Polonium and Radon halos. Note the similarity in sizes of the Radon-222 and Polonium-210 halos.

At this point, one of those rare and welcome "Aha!" experiences occurred as I realized that Radon is:
* A gas,
* An inert gas,
* Produced a few atoms at a time in the U-238 decay chain, continuously and steadily over geologic time.

There was therefore no reason to think that Radon manufactured in any nearby Uranium mineral particle (uraninite, betafite, uranophane, etc.) would stay attached to the disintegrating particle; an atom with a filled outer shell would not 'attach' to the biotite crystal's atoms, nor would it be likely to remain attached to the disintegrating Uranium mineral inclusion. Moreover, with about four days to move around as single atoms subject to thermodynamic gas laws, it could wander literally anywhere in the mica permitted by the slightest crack, cavity, lattice discontinuity, or separation between crystal planes, "pushed" along by new Radon atoms forming back 'behind' it in the inclusion.
So once a path is developed, it would be followed by other radon gas atoms, and over time would create the halo.

He even talks about how to test this explanation - by seeing if you can find the double rings.

Interestingly this pattern is discussed in another paper, Concentric rings of radioactive hal...a: a possible result of 238U chain decay, by Dipak C. Pal, Department of Geological Sciences, Jadavpur University, Kolkata 700 032, India:

Quote
Transmitted light microscopy of quartz-chlorite schist from Turamdih uranium deposit in Singhbhum Shear Zone has revealed the presence of distinctly circular aureoles of radiation damage, commonly referred to as radioactive halos or radiohalos, in chlorite surrounding inclusions of uraninite in the Turamdih uranium ore; particularly those surrounding tiny (< 2 mm) radiocentres show spectacular concentric aureoles. In well developed halos, four distinct rings of discoloration are clearly visible in host chlorite. The radiohalo pattern is in good agreement with the theoretical radiohalo pattern of 238U based on a-penetration ranges in air. Radii of individual rings surrounding tiny radiocentres (< 2 mm) in diametral/near-diametral sections are consistent and the mean radii of 32.4 mm (outermost), 22.0, 18.3 and 15.2 mm (innermost) compare well with the experimentally determined, theoretically calculated and observed penetration depths of a-particles emitted by 214Po (the outermost ring), 218Po, 210Po/222Rn, and 226Ra/234U/230Th (innermost ring) in biotite. Such ring structures can be assigned to the decay chain of 238U in which the above radioactive atoms correspond to daughters in the decay series and each of them emits a-particles of different energies. The undeformed circular nature of the radiohalos is indicative of their postkinematic origin. Petrographic studies also indicate possible mobilization of uranium by some later processes.
He starts with a generic discussion of halos and then moves on to the evidence for uranium halos, and concludes:

Quote
This study provides petrographic documentation of radiohalo patterns in chlorite caused by the decay chain of 238U. It has shown that the damage pattern and penetration depths of a-particles are similar to those found in biotite. To the best of the author’s knowledge, such studies are not available on natural chlorites, at least from India. The observational data presented here will add to the existing data and this study offers an opportunity for future research to characterize and understand the nature of radiation damages in sheet silicates in general and chlorite in particular, using modern techniques like laser- Raman spectroscopy, optical absorption micro-spectro- scopy, high-resolution transmission electron microscopy, etc. Preliminary investigation in this direction is currently underway. It is also interesting to note that although the rock is highly deformed, none of the radiohalos observed in the present study shows any signature of deformation of the host mineral. This is a clear indication of the postkinematic origin of the radiohalos. Trails of radiocentres with their characteristic radiohalos along foliation planes in tandem with the undeformed nature of the radiohalos are also possible indications of the post-kinematic origin for the radiocentres. Possible leaching of uranium by later processes may have important implications in U–Pb geochronological investigation.
So we establish that uranium halos do occur, with rings characteristic of uranium decay.

Again, this is a serious problem for anyone arguing for a young earth, as it takes hundreds of millions of years for them to form, due to the decay rate of uranium. You cannot say that Polonium halos are evidence but that Uranium halos are not: both need to be explained (if you are going to explain all the data).

Quote
So? I never suggested it did. Why should I address this now? It's pretty trivial business to find the error. Those who desire to divert their attention to this bunk, well, that's their own business.
Yes, evidence that the earth is old must be ignored, must be called "bunk," must be discredited without actually looking at the evidence: that is the hall-marks of cognitive dissonance in operation.

Why should you address it: because it contradicts and invalidates your argument, and to ignore it is to ignore reality and the objective evidence of reality.

There's more. This article, POLONIUM HALOS AND MYRMEKITE IN PEGMATITE AND GRANITE, by Lorence G. Collins, where he talks about some "Odd Circumstantial Facts":

Quote


When I looked closely into Gentry's Po halo studies, I noted four odd circumstantial facts contrary to his hypothesis. The first oddity is that his Po halos all occurred in granites and granite pegmatites, never in any other rock types, excepting locally near Bancroft.

In that area, the uranium-bearing calcite veins cross-cut the granitic rocks, and Po halos are absent from mafic rocks whether the mafic rocks are older or younger in age than the granites. This is true even when biotite is relatively abundant among the mafic minerals. These Po-halo-free rocks include biotite-bearing gabbros, diorites, and tonalites, as well as their volcanic equivalents. On the basis of field, chemical, and microscopic textural relationships, all of these mafic rocks are crystallized from magmas at high temperatures.

It is odd that Po halos are found only in certain, supposedly primordial, biotite-bearing granites and not in all primordial, biotite-bearing rocks. The Creator was evidently very selective about where he tucked the short-lived Po!

A second oddity I discovered was that all of the granites in which Gentry found Po halos also contain myrmekite. Myrmekite is a replacement mineral intergrowth, a fact that suggests that Po halos may not be present in all granites but only in granites formed by replacement processes. Conversely, perhaps only granites containing myrmekite should exhibit Po halos. In reality these do not always contain Po halos. Again, the Creator was very selective.

Some granites are derived from melted sedimentary or rhyolitic volcanic rocks, some by fractionation within magma (either partial melting or fractional crystallization), and some by partial melting and rising of magma that leaves behind a mafic residue (restite). Granites derived from melts do not contain Po halos.

The third oddity I noted is that Po-halo-bearing rocks are always associated with uranium concentrations. Gentry describes several uranium-rich localities that contain Po halos, including some in Finland, Sweden, Germany, Canada, and New England (Gentry 1988, page 36; Wiman 1930).

Why, one must wonder, would an all-powerful Creator choose to put Po halos only in rocks that contain abundant uranium? If Gentry is correct, and Po halos have no association with uranium, why does the Creator not put the Po halos also in granites free of uranium concentrations?

Polonium, being one of the daughter products of the radioactive decay of uranium, is expected to be found near uranium concentrations. To suppose a supernatural origin for the Po-halo-bearing granites is irrational.

A fourth oddity became apparent to me later as I delved into the detail of Gentry's hypothesis. Only selected Po halos, those for the isotopes 218Po, 214Po, and 210Po (products derived in 238U disintegration) have been found by Gentry (Dutch 1983; Gentry 1983). Potential Po isotopes of other mass numbers (215Po, 211Po, 216Po, and 212Po) are produced in the 235U and 232Th disintegration series (Fig. IV-8), but Po halos of these types are not found.

Why might the Creator not make Po halos of these other types, since all are available in nature? Does this unusual omission imply some simple natural cause for the selective presence of certain Po halos?
In other words, there is more to this story than just the existence of Polonium halos. He goes on to explain how normal physical and chemical processes can cause

That's twice you've shown that you're not paying attention. I recall that there is a good "young earth" argument associated with radiohalos, but we haven't been discussing it.

You haven't yet given a lick of evidence to support the assumption you claimed creationists were making, either. It was just more empty, hollow bunk. Spam away & let us see how many morons fall victim to your trickery. What's next? Apoloniogenesis?
That would be your argument from incredulity, strange how you predict your own behavior eh?

And meanwhile, the basic problem with the creationist argument is that if you have naturally forming modern Polonium, a modern source of Polonium, in such crystals, that then there is no argument that they represent a young earth, only recent (new) Polonium. Whether stated implicitly or not, the argument only works if you exclude naturally forming modern Polonium from making the halos.

The evidence shows that there is an explanation for recent (new) polonium added to these rocks by natural processes.

The evidence also shows that uranium halos exist and are numerous -- evidence of the fact that the earth is older than Polonium halos by hundreds of millions of years.

Quote
These same people openly assume decay rates are always constant, any time this assumption will help them produce evodates.
And if the decay rates did change, then the energy of the decay would change and the halos would be different: the uranium halos would be blurred over measurable distances instead of still found in the rings dictated by the energy of the decay in modern times.

Meanwhile, have you figured out where you were proven wrong (by mathematics) on half-life and your quarter life calculations?

Enjoy.

Here RAZD clearly identifies his target audience. He's out to fool those who don't follow links & examine the evidence for themselves. Look at how many sources he cites in order to create the impression that he's done his homework before trying to sneak this false claim in under the radar.

Changing the decay rate would result in more decay - not more energetic decay. In alpha decay, for example, more alpha particles would be produced in a given amount of time, but the energy of each alpha particle would remain exactly the same. The exact same halo would result, only faster. The energy contained by decay particles is a function of their source atom. It has nothing at all to do with how many atoms are decaying in a given timeframe.

Now, how many will call his bluff? That's the question. I expect at least a couple have already followed some links and come to understand the process of halo formation. They're immunized. Might be interesting to see the results if we could accurately poll the readership.

Funny that such a huge inconsistency in evolutionist fabrications should be written off as a distraction. The story trotted out to explain away polonium radiohalos is in direct conflict with one of the cornerstone assumptions used to produce evodates. Anyone who welcomes the suggestion to write this off as "just distraction" wants very dearly to be deceived.

I submit, RAZD, that you are most likely wasting your time. Such as want so desperately to deceive themselves can usually manage to achieve the goal.

Helium can follow smaller paths. And Radon is not known to suspend its own decay on whims.

It's not hard to understand that migrating radon will leave a tube-shaped trail as it decays. A further problem is that gases obey the same laws, so a gas will not migrate to a designated point and stop. It will fill whatever space is available, and maintain roughly equal pressure & density within the space.

To posit that any gas follows a path to a pinpoint, and compresses itself into a tiny space when other space is readily available is contrary to everything science knows about gases. Linear tried to make it look as if I am the one positing sentience among radioactive atoms...

Originally Posted by RAZD

This wouldn't result in spherical halos. Rather, a halo would be generated in the shape surrounding the entire space available to the radon gas.

Quote

A more direct test would be to pump radon gas through small paths in granitic rocks.

Dr. Gentry long ago challenged anyone to reproduce polonium radiohalos. As I said before, if they thought it could be done they'd accuse him of fraud. If this method would work, they would've produced their own halos artificially and accused him of faking the evidence.

A point not disputed. You & Linear will continue attempting to cause confusion between uranium halos & polonium halos. I will be clarifying & we'll see how this plays out. It is not a loss for me if those intending to be fooled are successful, and your continued attempts to obfuscate will make it obvious to the rest that you don't want them to know the truth.

Point for folks to remember: polonium halos will form right along with the rest of the halos of the decay series when uranium is involved. This is easily understood. All the radioactive materials sit in one place, and they all decay together, so all the halos form.

The problem for anticreationists is that polonium halos exist without "parent" halos. They are spherical, so they are post-kinematic.

The anticreation argument needs a means of transport that won't result in a traceable path. They need decay to be suspended, and only occur at the source & destination. They might as well posit Scotty beaming polonium into the granite. smilieteleport At least it'd fit the evidence.

I have not advocated dismissing any actual evidence. I don't call uranium radiohalos 'bunk', either. And I have considered them. I have evaluated the reasoning behind the "old earth" argument, and found it so obviously flawed that most folks should be able to find the flaw for themselves.

That's not an argument from incredulity. You claim there's an assumption and it doesn't exist. Pointing this out is not arguing from incredulity.

Okay Bugs, folks are really dumb enough to forget who pointed out that the argument over polonium halos is primarily about creation. I have not argued that they indicate an age.

Quote
Whether stated implicitly or not, the argument only works if you exclude naturally forming modern Polonium from making the halos.
The evidence excludes "daughter" polonium from making the halos, to the best of everyone's knowledge. The polonium halo evidence alone does not exclude earlier dates for the creation event. It does not exclude Scotty from manufacturing them with a transporter beam. It is the rest of reality which excludes these things.

Evosickness, or spam? I can't always distinguish which is which. And it could be this question is a case of false dichotomy.

Quote
These same people openly assume decay rates are always constant, any time this assumption will help them produce evodates.
And if the decay rates did change, then the energy of the decay would change and the halos would be different: the uranium halos would be blurred over measurable distances instead of still found in the rings dictated by the energy of the decay in modern times.

Meanwhile, have you figured out where you were proven wrong (by mathematics) on half-life and your quarter life calculations?

Enjoy.

Yes, the double talk gets old CTD.

Quote
Changing the decay rate would result in more decay - not more energetic decay. In alpha decay, for example, more alpha particles would be produced in a given amount of time, but the energy of each alpha particle would remain exactly the same.
You of course can prove this (the way you "proved" that 1/4 life resulted in a different rate of decay from a 1/2 life?). We can calculate the amount of energy for decay of atoms by e=mc^2 and the energy left over from the masses involved (M1 > M2 + mp, where M1 decays to M2 with mp being the particle) -- today -- however the energy to release the particle in the first place is tied to the decay rate:

Alpha Decay, Alpha detectors and id...Vance, chapters 1.3.4, 2.1, 6.2 and 8.4)

Quote
However, if the alpha has enough energy to surmount this barrier then it will regain that energy as electrostatic repulsion once it gets outside the range of the attractive strong nuclear force. One important consequence of this is that all alpha emissions have at least ~5 MeV energy. Furthermore, half-life is inversely related to decay energy.
(bold for empHAsis). Change the decay rate and you change the decay energy.

Another problem is that the very concept of a changing decay rate is a PRATT (CF210) with consequences:

Quote
The half-lives of radioisotopes can be predicted from first principles through quantum mechanics. Any variation would have to come from changes to fundamental constants. According to the calculations that accurately predict half-lives, any change in fundamental constants would affect decay rates of different elements disproportionally, even when the elements decay by the same mechanism (Greenlees 2000; Krane 1987).
You would need a fundamental change to physics in order to change the decay rates.

And of course this doesn't answer the question of HOW the decay rate is changed, and how it miraculously does not affect all the evidence that there has been no change in decay rates for billions of years (it can be observed in the old light from stars billions of light-years away).

Some minor changes can be effected, How to Change Nuclear Decay Rates, but not of much significance:

Quote
However, there are exceptions, the most notable being the the astrophysically important isotope beryllium-7. Be-7 decays purely by electron capture (positron emission being impossible because of inadequate decay energy) with a half-life of somewhat over 50 days. It has been shown that differences in chemical environment result in half-life variations of the order of 0.2%, and high pressures produce somewhat similar changes. Also, a recent paper measures a 0.8% reduction in half-life for Be-7 atoms enclosed within C60 cages. Other cases where known changes in decay rate occur are Zr-89 and Sr-85, also electron capturers; Tc-99m ("m" implying an excited state), which decays by both beta and gamma emission; and various other "metastable" things that decay by gamma emission with internal conversion. With all of these other cases the magnitude of the effect is less than is typically the case with Be-7.
Now I don't call less than 1% significant, especially when the measured rate of decay can be off by that amount based on empirical evidence.

So are you going to provide a mechanism and a mathematical model for changing the decay rate? Or are you just going to hide behind double talk and assertion.

Quote
The exact same halo would result, only faster. The energy contained by decay particles is a function of their source atom. It has nothing at all to do with how many atoms are decaying in a given timeframe.
When you change the physics to increase the decay rate you change the physics for the decay energy (to say nothing of bonding energy holding everything together). You also fry because you have multiplied the heat generated by decay by several factors.

Quote
Here RAZD clearly identifies his target audience. He's out to fool those who don't follow links & examine the evidence for themselves. Look at how many sources he cites in order to create the impression that he's done his homework before trying to sneak this false claim in under the radar.

Might be interesting to see the results if we could accurately poll the readership.
Another ad hominem, argument from incredulity, and now the logical fallacy of the appeal to popularity. Logical fallacies don't prove anything.

It used to be quite popular to think the earth was the center of the universe, and it used to be quite popular to think that gravity was according to Newton's formula (after he did away with a formerly popular notion). Popularity has nothing to do with reality.

Thanks again to RAZD for the science lesson. I'm in awe of the power of something most people don't think of every day: radioactive decay. All that energy inside the earth, billions of years after it formed. It's like that article I found which mentions an angular unconformity in the mountains of Scotland. These mountains themselves have been severely eroded over many millions of years. Yet within them is evidence of dramatic uplift in the even more distant past -- mountains which formed, eroded to the point where they were flat, sank, and received horizontal sedimentary layers on top. Within existing mountains which themselves are old.

Rocks. Simple, common things. They can teach us so much.

Jeanie,

Thanks, I understand that emotions are necessarily involved when dealing with beliefs, especially when confronting different beliefs. The key (I find) is to forgive anyone that makes ad hominems when they get frustrated by your arguments, and move on to talk about the issues.

Thanks again to RAZD for the science lesson.
Sorry that I can only brush the surface of what science says about radioactivity, as to delve much further requires some pretty intricate maths, the kind that makes eyes glaze over.

This article will give you an idea (unfortunately they use variables from previous definitions that are not defined, so it is hard to follow the formulas):

http://www.physics.queensu.ca/~phys490/Lecture/NucPart08_L15.pdf

Quote
Qα = Eb(Z, A) ? Eα(Z ? 2, A ? 4) ? Eα(2,4)

Now the we can translate the above condition for the possibility of an α-decay to Qα > 0. Fig. 14 shows a diagram with Qα-values for β-stable nuclei. Positive values start to appear for A > 150.

While the energy range of alpha-decays observed in nature is relatively narrow (~ 2 – 12 MeV) the lifetimes span a range from 10 ns to more than 1019 years. To better understand this behaviour we will investigate the mechanism of this decay a little closer.
...
So we find for the decay constant:
λ = w(α)v<sub>α</sub>e<sup>-G</sup>/2R
Perhaps LinearAQ can help with the maths. This picture may help:
[Linked Image]


The red line represents the energy level of the alpha particle, and the difference between inside and outside is the decay energy, Qα, while the decay shown is for the isotope in question. Long half life = little decay through the Coulomb Barrier = little difference in energy, so Qα is small, like 3 MeV for Bismuth 209 with a half-life of 10^19 years.

And because the decay while tunneling through the Coulomb Barrier is exponential, small variations in Qα are related to large variations in half-lives. Polonium 214 has a Qα of 7.69 MeV and a half-life of 0.000164 seconds.

So the fact remains that alpha decay energy and half-life are inter-related and you cannot change one without affecting the other.

So far, everything I have read shows that Polonium halos only exist in rocks that are infected with uranium inclusions and saturated in Radon, that they have been found in rocks of many different ages, that all such rocks also show Uranium halos, and that halos frequently overlap and follow visible fissures and cracks.

There is also this article
http://www.grisda.org/origins/15032.htm
Quote
Halo identification is achieved through the measurement of the halo diameter. The size of the halo and the half-life of the isotope producing it are related. Assuming that the half-life of the parent isotope has remained constant throughout the formation of the halo, the initial energy of the alpha particles that produced the halos can be determined, and hence the parent radioactive isotope identified. In making this identification, Gentry assumes, as do other scientists, a constancy of radioactive decay rate for polonium. However, Gentry also wants to invoke periods of time that "... may have been accompanied by an increased, nonuniform radioactive decay rate" (p. 134). If there were periods of nonuniform decay rates, identification of any pleochroic halo from its ring diameter would be questionable at best! All available data indicate that halo ring diameter increases with increase in decay rate. Either the rates remain constant or they do not. Evidence from other sources (1) suggests that the decay rates have remained constant for all radioactive isotopes. Several problems arise when one attempts to invoke increased decay rates while at the same time keeping the halo diameters constant! Such inconsistency cannot be considered as a satisfactory argument.
Greater decay rate, shorter half-life, larger diameter halo. Change the decay rate, change the diameter.

Enjoy.

Note: my time is limited, so I only choose threads of particular interest to me and I cannot guarantee a reply to all responses (particularly if they do not discuss the issue/s), and I expect other people to do the same. Thank you for your consideration.

My eyes are not glazed - they are dry, but yes - my brain hurts : ) Math does that to me. So RAZD - do you reject the possibility of God based on evidences that cannot be proven either way?

So I'm sorry if the truth hurts.

As Princess Irulan once said:

Deep in the human unconscious is a pervasive need for a logical universe that makes sense. But the real universe is always one step beyond logic.

Pseudo-evoscience has this obsessive compulsive need to answer every question, many of which only God has access to. This is why they will fail every time, blinded by their mythogical evo-pantheon. But their prayers to false gods fall on deaf ears - because they are imaginary. The bible is real.

Would you care to expound on that at all as far as what you mean by the statement: Rather, as reality IS what was created, science just adds to understanding.

How do you, then, relate God with our world? (If you're sure...if not, what do you think could be the case with what you know about how to put it together? Jury still out would you say?

The problem with proposing added energy is pretty obvious: one runs up against Conservation of energy. The energy of an alpha particle can't increase just because it is released ahead of a schedule set by men.

I hope folks will follow the link to the pdf, so they'll see that the context is different. If the author intended to assert some sort of universal law claiming higher decay rate always results in higher energy, he really should have omitted the chart that immediately follows the quote.

On said chart, directly below the number 96, I see a dot. There are dots surrounding this dot in all directions. Some have slower decay & lower energy. Some have slower decay & higher energy. Some have faster decay & lower energy. Some have faster decay & higher energy. All combinations of higher/lower energy and slower/faster decay are charted. So I conclude the author didn't intend to imply a universal law.

Such a law would naturally require a little more than say-so, before it could be considered scientific. And most such laws have names, if you think about it. I didn't see a name, so I think my interpretation is fairly safe.

Lost our way, have we? It is you who need to decide whether you want constant decay rates & polonium radiohalos stand, or whether you want variable decay rates and evodates fall.

Your attempts to explain away the radiohalos require suspension of decay during migration.

None of the logical fallacies you list are present in my post. I do not claim or imply that your argument is wrong because you are the source. I claimed it is wrong and implied you know it is wrong.

I didn't appeal to popularity to establish that I'm right about the issue. I didn't appeal to it at all, in fact. I should like to appeal to popularity for the purpose of discovering how successful you've been - nothing further. Don't know that'd I'd be keen on sharing the results with you either, if I had them.

As a matter of policy, I don't employ incredulity as an argument. On rare occasions I make special exceptions when I judge them to be warranted for purposes of humour and/or mockery.

Yes, and if you read the article you will see that this is discussed, this is called the Coulomb barrier or the Coulomb wall. The problem for you is that if there is no way to surmount the barrier/wall, that then there is no radiation. Because we do have radiation, we know this assertion is false.

The way the alpha particles get around the barrier/wall is by quantum tunneling, and you can calculate the probability of an alpha particle tunneling through the barrier with standard field equations. Curiously this is what tells you the decay rate of the isotope.

Indeed I hope they do follow the link, as then they can see that all the dots on the line labeled 96 are in line, as are each of the dots on the other lines labeled with different numbers of protons (that's what the "96" represents). The lines are roughly parallel, and thus they show similar changes in alpha particle energy with the different numbers of protons in different isotopes (which is also predicted by the energy calculations). This kind of multi-line graph is commonly used to show the effects of three variables on the interactions, particularly when one variable, proton number, is an integer.

These lines clearly show that for any isotope (any set number of protons) there is a line showing a direct relationship of alpha particle energy to half life, and that if you change the decay rate (half life), you then change the alpha particle energy by an inverse logarithmic relationship.

Seeing as your initial premises, based on misunderstanding of the physics and the graphs, are invalid, this means that any further conclusions you have are irrelevant, and so I don't need to reply to them.

What uranium halos show is that the energy of alpha particles from uranium decay have not changed during the course of the formation of the uranium halos.

Because the alpha particle energy is inversely related to the log of the decay rate half-life, and you cannot change the decay rate without changing the alpha particle energy, this means that the decay rate for uranium has not changed during the formation of the uranium halos.

Because the uranium halos take several hundred million years to form with this decay rate, the earth is at least several hundred million years old -- since the rocks cooled to form the crystals.

Enjoy.

That's not the same thing. First of all, there may or may not be a mechanism which controls the timing of decay. Nobody has yet discovered one. You want to claim "quantum tunneling" is the means of decay? This is an ineffective dodge. You still need to answer the timing issue. What allows one particle to tunnel, while preventing another? Do the atoms poll their neighbors? How do they know when to decay? Who sets their schedule?

Quote

The problem for you is pretty clear. This isn't what I argued. I never said there is no decay. I noted that your migration stories require decay to cease, but I never advocated the position for one instant. If this is a problem for anyone, it's a problem for talkdeceptions, Linear, and yourself.

Quote

Nothing curious at all about it, except that anyone would try to pass it off as a "prediction". That, and the idea that anyone would bother with such a roundabout method of calculating.

Yes, and the chart's been jimmied quite a bit to obtain straight looking lines. Note the numbers on the horizontal and vertical scales, and their spacing. Presenting this chart to an educated audience who understand that the lines are actually curves is one thing. Trying to pass them off as actually straight is another.

Neither the article nor the chart discuss changing decay rates. They discuss some examples of observed decay rates. RAZD extrapolates and asserts a new, unnamed, unrecognized law. I do not imply that he's the first, so the "law", if it ever is recognized, may well bear someone else's name.

What uranium halos show is that the energy of alpha particles from uranium decay have not changed during the course of the formation of the uranium halos.
What polonium halos show is a phenomenon which can only be plausibly explained by confessing "God did it."

Thanks again, CTD for demonstrating the depth of your knowledge.

That's not the same thing. First of all, there may or may not be a mechanism which controls the timing of decay. Nobody has yet discovered one. You want to claim "quantum tunneling" is the means of decay? This is an ineffective dodge. You still need to answer the timing issue. What allows one particle to tunnel, while preventing another? Do the atoms poll their neighbors? How do they know when to decay? Who sets their schedule?
Your lack of knowledge of a mechanism does not mean there isn't one, nor that the process is not well understood by physicists -- the ones measuring the data and making those graphs that show the relationship, and that the experimental results match the calculated decay rates and alpha energies.

Quantum tunneling is based on quantum mechanics, which is calculated with field equations. These are based on probabilities due to the uncertainty principle, the principle that says we can't know which two protons and two neutrons will come together and tunnel out of an atom or even which atom it will tunnel out of ... however, like calculating the probability of flipping coin can predict the overall results while being totally incapable of predicting a single toss, probability calculations can predict the overall effects:

Decay will happen when the appropriate combinations make an isotope radioactive, and energy of the alpha particle will be related to the decay rate.

Quote
The problem for you is pretty clear. This isn't what I argued. I never said there is no decay.
It doesn't matter what you fail to discuss, or how you try to move the goalposts around, as the fact is that without quantum tunneling decay would not exist. When proton and neutron, alpha particles and the nuclei of larger atoms combine they give up energy, and they can't undo that combination without adding that energy back.

We know that decay does occur. Nobody said that you said that it didn't, the point is that quantum tunneling explains how decay does occur. It also explains the energy of the alpha particle and how it is related to the decay rate.

I noted that your migration stories require decay to cease, but I never advocated the position for one instant. If this is a problem for anyone, it's a problem for talkdeceptions, Linear, and yourself.

Not at all, as this is your argument, your straw man, and it is obviously false as well.

The rocks that show polonium halos are infected with uranium inclusions and uranium halos, and they are saturated in radium, a gas that readily dissolves in water as well. These rocks also show fissures, cracks and minute pockets where the radon gas or radon carrying water can easily reach, and along those fissures -- because of the radon being saturated through the rock -- we should see your "migrating tunnel" if your assertion were true, and we don't. Not one. Anywhere. Therefore your claim that a "migration tunnel" would have to form is falsified by the evidence. Simply put, you are wrong (again).

What do we see? We do see tracks with halos like beads along the fissures and cracks, often overlapping, but alway centered on concentrations of deposited polonium.

It is not a conclusion of scientists that this would occur, it is another of the observed pieces of evidence that shows that radon does cause polonium halos along fissures and cracks.

Nothing curious at all about it, except that anyone would try to pass it off as a "prediction". That, and the idea that anyone would bother with such a roundabout method of calculating.
Curious that you contradict your own earlier statement: "You want to claim "quantum tunneling" is the means of decay? This is an ineffective dodge.

Yes you can see how "jimmied" the lines are. The horizontal scale, by the way, is logarithmic, so that exponential (curved) functions show up as straight lines, standard practice in science.

Sadly, for CTD, it looks like he is wrong again.

Failing to make a stupid argument is something I try to do often. It hardly constitutes "moving goalposts".

Straw man? Your own source said that spherical halos indicate post-kinematic formation. Let me spell that out: decaying elements which are moving don't make spheres.

So you contradict your own source, and common sense & invoke magic migration? Fine. I'm willing to leave it at that.

The pics show where the fissures are in relation to the halos. If there were so much all-fired "saturation", there would be halos surrounding these fissures. But hey - have your silly magic.

To make it doubly clear. Migration leaves telltale signs. RAZD says this is false because there are no telltale signs. Science (both creationists and RAZD's source) says no telltale signs = no migration. But RAZD insists there must have been migration, and it somehow left no evidence.

The pictures show what paths are available for migration, and they don't meet the requirements.

Even magic migration wouldn't solve his problem; that's what's even funnier. Unless it's polonium doing the magic migrating. Anything else, any of the "parent" elements, would have to decay at the destination, and guess what! This decay would leave evidence. It would make its own halo. So, just to be fair, I should ask: is it polonium migrating magically?

(Is anyone counting how many ways the migration fantasy is wrong? I don't know if records are kept, but this is pretty impressive.)

Actually my argument remains clear and valid. Your attempt to snip a piece out of context has failed here, in case you didn't notice. There's no contradiction. Try not to bungle your next out-of-context quote. It wouldn't be as funny the second time around.

Strangely that is not what is meant by "postkinematic" in geology.

http://geology.geoscienceworld.org/cgi/content/abstract/21/10/925
Quote
Intrusion of late-stage granitoids into Archean granite-greenstone terranes may be spatially and temporally related to late-orogenic upper-crustal extensional collapse and formation of metamorphic core complexes. The late- to postkinematic granitoid magmas are derived through partial melting of upper mantle and lower crustal sources, and are locally associated with late-stage extensional structures. Thick roots of depleted lithospheric mantle of Archean age (tectosphere) beneath Archean cratons makes melting of the upper mantle difficult. It is proposed that the Archean tectosphere is made of imbricated slabs of buoyant Archean oceanic crust and lithosphere, together with trapped wedges of "fertile" mantle; this would explain several seemingly contradictory phenomena. Decompression from upper crustal extension generates significant amounts of basaltic melts from the trapped wedges of fertile mantle. These basaltic magmas intrude and partially melt the lower crust; becoming more silicic in composition, they migrate upward to solidify in the middle and upper crust, forming the late- to postkinematic granitoid suite. The tectosphere in this model is less dense and colder than surrounding asthenosphere and is consistent with eclogitic xenoliths from subducted oceanic lithosphere found entrained in kimberlites. The direction and magnitude of shear- wave anisotropy in the upper mantle is also explained in this model through the orientation of olivine crystals in the underplated slabs of oceanic lithosphere.
You will notice that they are not talking at all about elements moving along cracks, but about the geological processes of rock formation, how it is deformed and remelted by kinematic processes, and that there are stages in that development that include late-kinematic and post-kinematic formation of the rocks.

When the scientist says that the intrusions that form polonium halos are post-kinematic, he means they came after the rock was formed. After the rocks were created.

Sorry, CTD, I thought you understood that this too is a logarithmic scale, a more obvious one than the other, because it has a 1 instead of a zero point. I grew up using a slide rule, so I know what logarithmic scales look like. It's just math, not science. Exponential functions plotted on log-log graphs will be straight lines.

It isn't unusual for jargon to develop, but that's not the case here.

Geologists mean the same thing as everyone else when they employ the term kinematic.

Actually, they were very much talking about elements moving along cracks, only on a different scale. But even if they weren't, it wouldn't matter. If you want to build a linguistic argument based upon a single sample... Shoot! That might be a fun game to play after all. Anyone up for starting a thread on it?

For those playing along at home, you will recall that radiohalos cannot even form until there's solid rock.

'Post-kinematic' can refer to "after the rocks were created" or it can refer to other things.

How impressive! Thanks for condescending to disclose the logarithmic nature of the graph. I wish that all facts could be pried loose in so few posts. But at any rate, I shan't have to demonstrate this one in the face of unrelenting obfuscation.

Stand by to laugh or cry, depending on your position & disposition.

I think it's time to conclude my participation in the radiohalo discussion - for now at least. I've been researching a little more, and I've found out that I was mistaken to focus on the formation of tubes around the migration paths.

To be sure, they'd form. There's no way around it. But I looked into alpha-recoil tracks and found that they're much more devastating. When alpha decay occurs, the nucleus of the decaying atom recoils in the opposite direction. If it occurs in rocks, this creates clear tracks even if the atom was part of a solution.

But that's not the good part. That's not taz or laughroll material. Well, yes it is. But it gets better. Once again, let's look at one of RAZD's sources.

The suggested decay chain for Polonium is as follows. (I have begun the chain at Radon-222, fifth in the series of alpha particle- emitting daughters of Uranium-238, both for brevity and for another reason which will shortly become clear.)

86 Rn 222 (86 protons, Radon, mass 222) decays in about four days to Polonium-218 with the emission of an alpha particle of 5,486,000 electron volts (5.486 MeV). (Please note this energy value.)

84 Po 218 (84 protons, Polonium, mass 218) decays, through two additional non-alpha-emitting (beta decay) steps involving Lead and Bismuth, over a total of about 45 minutes, to Polonium-214 with the emission of a 6.111 MeV alpha particle.

84 Po 214 (84 protons, Polonium, mass 214, arriving via Lead-214 (27 minutes) and Bismuth 214 (20 minutes)) decays through two additional (and time-consuming) steps taking about 21 years, to Polonium 210, with the emission of a 7.687 MeV alpha particle. This involves the immediate alpha decay (.000164 seconds) of the Po-214 nucleus to Lead 210, which has a half-life of 21 years, then via beta decay to Bismuth 210 with a 5 day half-life, and another beta decay to Po 210. (There is a small chance of the Bismuth 210 appearing in its isomeric form, which has a half-life of three million years.) This Polonium-214 alpha energy is the highest in the Uranium 238 decay chain, and consequently creates the largest, outermost, halo.


84 Po 210 (84 protons, Polonium, mass 210) decays with a half-life of 138 days directly to Lead 206 (stable), emitting an alpha particle of 5,305,000 electron-volts' energy. (Note the close similarity between this energy and that of the decay from Radon 222 to Polonium 218.)

82 Pb 206 (82 protons, Lead, mass 206). End of the line. Stable Lead. No further decay is possible.
[Linked Image]
Figure 1. Polonium and Radon halos. Note the similarity in sizes of the Radon-222 and Polonium-210 halos.

At this point, one of those rare and welcome "Aha!" experiences occurred as I realized that Radon is:
* A gas,
* An inert gas,
* Produced a few atoms at a time in the U-238 decay chain, continuously and steadily over geologic time.

There was therefore no reason to think that Radon manufactured in any nearby Uranium mineral particle (uraninite, betafite, uranophane, etc.) would stay attached to the disintegrating particle; an atom with a filled outer shell would not 'attach' to the biotite crystal's atoms, nor would it be likely to remain attached to the disintegrating Uranium mineral inclusion. Moreover, with about four days to move around as single atoms subject to thermodynamic gas laws, it could wander literally anywhere in the mica permitted by the slightest crack, cavity, lattice discontinuity, or separation between crystal planes, "pushed" along by new Radon atoms forming back 'behind' it in the inclusion.
So once a path is developed, it would be followed by other radon gas atoms, and over time would create the halo.

He even talks about how to test this explanation - by seeing if you can find the double rings.


Note that all migration scenarios presented thus far feature radon or one of its parents. Note that in the decay sequence, Po 218 is an "ancestor" of Po 214. Ready?

It turns out that some of the radiohalos are Po 214 radiohalos all by their lonesome! Orphans with no evolutionary tree behind them.

Now we've seen that migration is bogus at least 3 ways (I honestly quit counting & don't care to spend my time reviewing over it). But even if Scotty shows up to smilieteleport radon from point to point, this mode of migration still won't result in orphan Po 214 halos. (Mr. Scott must beam Po 214 - parents won't do.)

Part of understanding evomyth is looking closely at the data they spout. You cannot disprove it until you analyze it carefully. And it is only then that we see a very intricately laid web of lies and deceit suspended before our very eyes. But at the end of the day, they're the real losers (the evorabble, clad in their evogoggles). They can wish the bones tell us something they do not but that doesn't make it a reality.

As Gurney Halleck once said: If wishes were fishes we'd all cast nets.

What these so called "scientists" conveniently ignore time and time again is that the fossils date the rocks and the rock date the fossils. Thus, there's no igneous rock to give a radiometric date for strata above or below a fossil. Paradox alert, folks! If I can't trust the geological column, how can I accept stratigraphic comparisons? The only dates we can get from fossils are relative.

It's also convenient that the scientists of Satan (and here I mean evolutionists - I don't say this to be cruel, simply factual) ignore findings like that of the nephilim while they piece together random human and monkey fossils and give it a name like neanderthal!

Rubbish! I've said it before and I'm saying it now. Evolution equals religion. The holy bible equals reality.

Is your religion real when it costs you nothing and carries no risk? Is your religion real when you fatten upon it? Is your religion real when you commit atrocities in its name? Whence comes your downward degeneration from the original revelation?

That all makes sense. I believe what I do (am an old earth creationist with a twist, I guess you could say.... I only believe human history goes back the 6000 years as stated with Adam and Eve) but that the earth could be much older...) and haven't gotten into the actual scientific issues much. (Haven't felt the need to). But this is intriguing. I have to say, though, Alia, I did not think that was very sensitive to post someone should die.... That really creeped me out.... (The reference to witches).

This is good, though! We need more stuff like this! Can you explain the rock, fossil issue? And the nephilim? I've brought up the giant issue with no response other than some on a religious basis I don't quite get or see.

Equivocating now? Yes, they were talking on the scale of the rocks moving as a whole and as they moved, cracking and carrying the cracks with them. In either case they referred to post-kinematic as the period after the rocks had stopped moving. Curiously the people in the sciences get to determine how to use the terminology used in the science.

For those playing along at home, you will recall that radiohalos cannot even form until there's solid rock.
And then at any time after the rock has solidified. Of interest here is that the rocks have not only solidified, but that they have cooled, cracked, moved and cracked some more, and that after this has occurred the rocks are free to be inundated with radon gas and radon carrying water, along with minerals that then can refill the cracks. See Post 39962 again:

There's more. This article, POLONIUM HALOS AND MYRMEKITE IN PEGMATITE AND GRANITE, by Lorence G. Collins, where he talks about some "Odd Circumstantial Facts":

[quote]When I looked closely into Gentry's Po halo studies, I noted four odd circumstantial facts contrary to his hypothesis. The first oddity is that his Po halos all occurred in granites and granite pegmatites, never in any other rock types, excepting locally near Bancroft.

In that area, the uranium-bearing calcite veins cross-cut the granitic rocks, and Po halos are absent from mafic rocks whether the mafic rocks are older or younger in age than the granites. This is true even when biotite is relatively abundant among the mafic minerals. These Po-halo-free rocks include biotite-bearing gabbros, diorites, and tonalites, as well as their volcanic equivalents. On the basis of field, chemical, and microscopic textural relationships, all of these mafic rocks are crystallized from magmas at high temperatures.

It is odd that Po halos are found only in certain, supposedly primordial, biotite-bearing granites and not in all primordial, biotite-bearing rocks. The Creator was evidently very selective about where he tucked the short-lived Po!

A second oddity I discovered was that all of the granites in which Gentry found Po halos also contain myrmekite. Myrmekite is a replacement mineral intergrowth, a fact that suggests that Po halos may not be present in all granites but only in granites formed by replacement processes. Conversely, perhaps only granites containing myrmekite should exhibit Po halos. In reality these do not always contain Po halos. Again, the Creator was very selective.
In other words, Polonium halos only occurred when the rocks in question were infected with uranium, saturated with radon and had mineral replacement happening along cracks, crevises and fissures, mineral replacement that is not restricted from carrying radon along with it.

In other words, the Polonium halos only occur in rocks where this infusion of radon gas can occur.

To be sure, they'd form. There's no way around it.
There would be decay along the paths, but you have some logical issues with this decay forming tunnels. Consider when a particle decays: it fires off an alpha particle at a random angle in 3D space, and NOT perpendicular to the fissure. The probability of the particle being fired on a perpendicular path is very small, most will be fired ahead or behind and the distance from the crack will be random. Result: no (visible) tunnel.

Conversely any small void or slightly larger space would contain more of the radon carrying water, and thus have increased probability of decay occurring from the same relative position, thus resulting in halos along the fissures, cracks, and crevices -- as observed.

Quote
But I looked into alpha-recoil tracks and found that they're much more devastating. When alpha decay occurs, the nucleus of the decaying atom recoils in the opposite direction. If it occurs in rocks, this creates clear tracks even if the atom was part of a solution.
And this is another red herring.

How impressive! Thanks for condescending to disclose the logarithmic nature of the graph. I wish that all facts could be pried loose in so few posts. But at any rate, I shan't have to demonstrate this one in the face of unrelenting obfuscation.
Sorry CTD, but I can't anticipate what it is that you don't know. You comment as if you know what you are talking about, CTD, yet you demonstrate time and again, not just here on the graph and your "tunnel" formation and in your "quarter"-life calculations, but several other places, that there are things that you just do not understand. We don't know what they are until you make these bogus comments rather than ask for explanation.

That you do not have the math or the science background to enable you to understand these things is not your fault, and lack of understand thus is not "bad", but what I find disturbing is that you seem to prefer pretending not only to understand but that you have some knowledge and authority to comment instead of asking for clarification.

The fact remains: change the decay rate, and you change the alpha particle energy, and this changes the radius of the halo. Uranium halos show no variation in ring size, therefore there was no change in alpha particle energy while they were formed, and as they took several hundred millions of years to form, the earth is old.

Not what he said. Not even close, and the text's right there for everyone to see. His main point is to question the "choices" of "the Creator", and he never mentions radon saturation at all. You even have to put words into your own source's mouth, it seems.

Or maybe Professor Collins didn't know what he was saying until RAZD made his argument for him?

I guess the Po 214 halos are a red herring too, since you have no answer for them either.

Should've just written off all radiohalos as "red herrings" from the start, rather than waste everyone's time with your smokescreens.

But for everyone else's benefit, alpha-recoil traces aren't hard to spot, and they would have to be present if migration took place. And even migration fantasies can't explain away parentless Po 214 halos. Kinda why I figured it was time to stop talking about them. It's just "rubbing it in" at this point. There's no sport left at all (not that there was really much to begin with).

Now you are trying to confuse the issue with "hollow" tunnels versus tubes, when I never said hollow.

Curiously this latest attempt at diversion does nothing to answer the mathematical problem of your tube formation. It still won't form the way you think it will no matter how many times you repeat yourself.

Just for fun, let's look at what you would actually see:

[Linked Image]
http://www.csun.edu/~vcgeo005/lc8-4.html


Note that this picture (taken by Dr Collins) is of a fracture that extends into the rock away from the surface shown, and that the scattering seen is also extending into the rock each side of the fracture.

What you DO see is a scattering of damage along the fracture. Curiously this scattering is precisely what I said would occur, rather than your well defined "tubes" ... and if you look perpendicular to the fracture you (a) would not see the fracture and (b) would not see the scattering as anything different from the background.

The True Origin of Polonium Halos

Biotite and coexisting myrmekite are both formed during replacement processes in a granite. It follows that Po halos in biotite that coexists with myrmekite must also be attributed to replacement processes.

The properties of radon are germane to this understanding. Radon (222Rn) is the radioactive decay product of 226Ra which evolves into 218Po. As an inert gas, it (222Rn) moves freely through cracks in rocks unimpeded by reactions with minerals lining the cracks. Evidence for this ease of radon travel is noticeable in water wells prior to earthquakes. The creeping rock movements associated with seismically-active terranes open avenues for radon-bearing water to move into lower-pressure pore space and to the surface. Therefore, on the basis of this mobility, we would expect radon to move into a shattered and sheared habitat of diorite or gabbro that was in the process of being converted to myrmekite-bearing granite.

As 222Rn is the precursor for 218Po, this polonium isotope is the first one to be formed in the decay process. Although the half life of 218Po is relatively short (3.05 minutes), enormous numbers of 222Rn concentrate as a dissolved element along with silica in hydrous fluids, which then migrate in response to tectonic pressures into porous sites in the mafic crustal rocks.

Two factors favor diorite or gabbro sites for the formation of Po halos in conjunction with myrmekite-bearing granite and pegmatite development.

(1) Biotite (a common mineral in some diorite or gabbro) is cleavable easily on the planar "leaves" of biotite "books." These cleavage surfaces constitute porosity into which hydrous fluids carrying radon gas can move.

(2) In both biotite and fluorite the crystal lattices contain sites whose negatively charged fluoride ions (F) or hydroxyl ions (OH-1) can be accommodated. These lattice sites are relatively large, and provide space where similar-sized ions can enter and take up lattice positions.

When atoms of 222Rn decay to form in succession 218Po, 214Po, and 210Po, the three polonium isotopes exist as negatively charged ions, Po-2, whose sizes are similar to the fluoride and hydroxyl ions. In this way polonium isotopes are naturally accommodated and concentrated into fluorite (CAF2) and biotite in granitic rock that is subjected to shear stress.

Thus, polonium was deposited in new crystals that grew from voluminous hydrothermal flushing of sheared and fractured, formerly-solid, mafic rock. Quartz and exotic minerals replaced mafic minerals, creating granite and pegmatite in their place. Two receptive mineral structures, (1) biotite cleavability (giving permeability to radon-carrying fluids) and (2) open-lattices in both biotite and fluorite crystals, explain why those minerals become repositories for polonium, and why the tracery of Po halos prove its ephemeral presence. The large volumes of hydrothermal fluids involved in this process are compatible with rapid growth of large pegmatite crystals of fluorite, biotite, and other minerals.

In the wall rocks near such shattered zones, where small primary crystals may be disseminated in the original diorite or gabbro, the stresses can shear them, and thus allow introduced fluids to aid recrystallization, by the annealing of microfractures, and secondary growth that enlarges the crystals. Since the large "books" of biotite in pegmatite and the small crystals of biotite in adjacent granite both develop through replacement processes at temperatures below the mineral melting intervals, these biotites and fluorites, whether growing or recrystallizing, provide ready-made lattice sites for rapid precipitation of polonium ions. Simultaneous growth of this kind of biotite and fluorite along with movement of dissolved 222Rn atoms into the crystals enables rapid accumulation of Po isotopes. These concentrations then decay to produce the Po halos.

The volumes of radon that emerge from deep in the Earth's Crust, dissolved in hydrous emanations, can be tremendous where uranium is abundant. Concentrations of this ambient radon can provide the enormous numbers of atoms needed to produce the Po decay halos. Radon emanating from a uranium source is a continuous chain of disintegration episodes that can provide a constant supply of new gas to a diorite or gabbro body as it is transformed into granite or pegmatite.

From these insights it follows that Po halos in a granite need not have been produced in a short time. Some halos may have formed early, some later. Rapid entry of radon and precipitation of polonium could occur if a gabbro or diorite site were made porous and depressurized by tectonism.

The frequent coexistence of Po halos in biotite with myrmekite in plagioclase and microcline of the same rock fabric gives a clear indication that a progressive replacement process in solid, unmelted rock has taken place. No magma is involved in this process.

Finally, the presence of 218Po, 214Po, and 210Po halos only in granites and pegmatites and the absence of 216Po, 212Po, 212Po, and 211Po halos in these same rocks become understandable. Three rationales attest to this logic.

First, the half lives of radon isotopes for the different Po isotope precursors are diagnostically different. For 222Rn in the 238U series [the source for the observed Po halos], the half life is 3.82 days. By contrast, for 219Rn in the 235U series, the half life is 3.92 seconds, and for 220Rn in the 232Th series, the half life is 54.5 seconds. The 222Rn has about 84,000 or 6,000 times as much time to enter the biotite as does 219Rn or 220Rn!

Second, the 216Po, 215Po, 212Po, and 211Po daughter isotopes have half lives that are measured in fractions of seconds rather than the 140 days for 210Po and 3.05 minutes for 218Po. The 210Po has over three million times the longevity of the sister series equivalents!

Third, the relative abundance of released 222Rn gas is proportionately much greater in most terranes than the abundances of released 219Rn and 220Rn gas.

Therefore, the combination of extremely short half lives of 219Rn and 220Rn gas [and their daughter polonium isotopes] and the relatively small quantities generated make the formation of 216Po, 215Po, 212Po, and 211Po halos impossible. These isotopes of radon and polonium, which could produce the missing Po halos, convert to Pb isotopes so quickly that their radon gas can never travel far from its source before decaying. Polonium from these isotopes can never migrate to and accumulate in distant biotite and fluorite in sufficient quantities to produce any halos.
He goes on to show how he tested his concept that radon was the source of the polonium halos, and then reaches this conclusion:

Quote
Polonium Halos Explained

The formation of granite by replacement of solid rocks means that Gentry's theory is no longer tenable. He can no longer legitimately say that Po-halo-bearing granites must form by supernatural means.

Solid diorite and gabbro rock, which had previously crystallized from magma, has been subjected to repeated cataclasis and recrystallization. This has happened without melting; and the cataclasis provided openings for the introduction of uranium-bearing fluids and for the modification of these rocks to granite by silication and cation deletion.

In uranium ore-fields the extra uranium provides an abundant source of inert radon gas; and it is this gas that diffuses in ambient fluids so that incipient biotite and fluorite crystallization is exposed to it. Radon (222Rn) decays and Po isotopes nucleate in the rapidly growing biotite (and fluorite) crystals whence they are positioned to produce the Po halos.

The whole process of Po halo formation can be accomplished without calling on a Creator to do it. The serendipity that has emerged from these observations implies that Po halos in myrmekite-bearing granite indicate a non-magmatic origin for the granite. The argument comes full circle when it meets Gentry's initial [truthfully made] observation that magmatically-derived granites cannot contain Po halos: the half-lives of the Po isotopes are simply too short.
Now let me repeat my comment that you said was "Not what he said. Not even close, and the text's right there for everyone to see."

Quote
In other words, Polonium halos only occurred when the rocks in question were infected with uranium, saturated with radon and had mineral replacement happening along cracks, crevises and fissures, mineral replacement that is not restricted from carrying radon along with it.

In other words, the Polonium halos only occur in rocks where this infusion of radon gas can occur.
Seems pretty similar to me.

As they say in forensics, we have means, motive and opportunity: we can logically, and with no great strain, conclude that Radon is the source of the Polonium that forms the halos. All the Polonium halo rocks are infested with uranium and saturated with Radon. Geological processes, including recrystalization, after the rocks had stopped moving (post kinematic) provided opportunity for Radon to seep into the nooks and crannies of the granite long after the formation of the granite.

Quote
So how about you renounce evolutionism & call me stupid & save some time? Deal?
Curiously I don't call people stupid. Nor would validation of polonium affect evolution.

Polonium is debunked as evidence of a young earth (once again), and meanwhile you still need to deal with uranium halos and the evidence for an old earth.

Here's another tidbit from Wiens:

Quote
Extinct Radionuclides: The Hourglasses That Ran Out

There is another way to determine the age of the Earth. If we see an hourglass whose sand has run out, we know that it was turned over longer ago than the time interval it measures. Similarly, if we find that a radioactive parent was once abundant but has since run out, we know that it too was set longer ago than the time interval it measures. There are in fact many, many more parent isotopes than those listed in Table 1. However, most of them are no longer found naturally on Earth--they have run out. Their half-lives range down to times shorter than we can measure. Every single element has radioisotopes that no longer exist on Earth!

Now, if we look at which radioisotopes still exist and which do not, we find a very interesting fact. Nearly all isotopes with half-lives shorter than half a billion years are no longer in existence. For example, although most rocks contain significant amounts of Calcium, the isotope Calcium-41 (half-life 130,000 years does not exist just as potassium-38, -42, -43, etc. do not (Fig. 7). Just about the only radioisotopes found naturally are those with very long half-lives of close to a billion years or longer, as illustrated in the time line in Fig. 8. The only isotopes present with shorter half-lives are those that have a source constantly replenishing them.
Just one more in a long string of pieces of evidence that the earth is old.

Note that Polonium falls into the category of being constantly replenished.

The question commonly arises whether the decay constants used in the isotopic dating of geological materials are actually constant, or do they vary in response to some external force?

The answer is that the decay constants used in the dating of geological materials are effectively constant and invariant to external forces.

The behavior of radioactive isotopes has been the focus of international scientific study since they were first recognized by Henri Becquerel in the late Nineteenth Century, and that behavior is now well understood.

The primary isotopes used to date rocks and minerals are given in the following table (Dalrymple, 1991, p. 80; Faure, 1986):

url=http://www.baylor.edu/Geology/index.php?id=26725(see link for table)[/url]

The mechanisms of radioactive decay that are relevant to the dating of geological materials include beta decay, electron capture and alpha decay. The effect of beta decay is that a neutron is converted to a proton within an atom's nucleus, accompanied by the ejection of an electron and an antineutrino from the atom. For a given atom, beta decay leads to an increase in atomic number by 1, and no change in the atomic mass number. Electron capture has the opposite effect, and occurs when an electron from the innermost orbital of an atom is captured by the nucleus, leading to the conversion of a proton into a neutron. For a given atom, electron capture leads to a decrease in atomic number by 1, and no change in the atomic mass number. Heavier radiogenic elements may undergo alpha decay, in which two protons and two neutrons are ejected from the nucleus, reducing the atomic number by 2 and the atomic mass number by 4.

The possible effects of changing temperature, pressure, chemical state, and electric or magnetic field strength on the three decay mechanisms relevant to geologic dating have been intensively studied, both theoretically and experimentally. These studies have shown that changing environmental conditions have either no measurable effect or a negligible effect (less than 1%, and that only for 7Be, which decays through electron capture) on the rate at which the decay processes occur (Dalrymple, 1991, p. 86-90). "There is no evidence that decay constants have changed as a function of time during the history of the solar system" (Faure, 1986, p. 41).
In other words, scientists that understand the variables and relations have looked into the question and have found absolutely no evidence that the decay rates have changed. Just like the uranium halo, the evidence shows continued constant decay over billions of years.

Enjoy.

True, the discussion of your attempt to use your version of math to throw doubt into the validity of the radioactive decay dating method is being discussed in that thread. However that is only to show that when you are wrong you can't seem to bring yourself to acknowledge it.
So, if you wish to continue to discuss decay rate mathematics here and show us how the calculation of decay rates is in error, go for it.

For the benefit of those who may not recognize false statements when they're openly presented, and because I have some time to kill, I'll debunk a little more.

Actually this must've been at least a double mistake: saying 'tube' when I meant 'tunnel' but really should've said 'tube' in the first place, which I actually said, but... shiftyeyes How many mistakes was I making after all is said & done?
Now you are trying to confuse the issue with "hollow" tunnels versus tubes, when I never said hollow.

Curiously this latest attempt at diversion does nothing to answer the mathematical problem of your tube formation. It still won't form the way you think it will no matter how many times you repeat yourself.

Just for fun, let's look at what you would actually see:

[Linked Image]
http://www.csun.edu/~vcgeo005/lc8-4.html


Note that this picture (taken by Dr Collins) is of a fracture that extends into the rock away from the surface shown, and that the scattering seen is also extending into the rock each side of the fracture.
Note that the picture clearly shows a tube forming from the right side toward the center. It's just RAZD presenting evidence that he's wrong, hoping you'll assume nobody would ever do such a thing so it must support him somehow, even though it doesn't look like it.

But anyone who can see the picture can see that it conforms to what I said. Trust your own eys - not RAZD's words.
Quote
What you DO see is a scattering of damage along the fracture. Curiously this scattering is precisely what I said would occur, rather than your well defined "tubes"
What a joke. The fracture dictates the shape of the surrounding field of discolouration. And any discolouration at all is evidence that migrating radon can't pass through the rock without leaving telltale marks. Now look at the pics of radiohalos and see if there's evidence of radon traveling through the regions around them. If there was, it would indicate migration.

The alpha-trace method is even better, since the trace marks show right up individually, rather than gradually building up discolouration fields.

Not what he said. Not even close, and the text's right there for everyone to see. His main point is to question the "choices" of "the Creator", and he never mentions radon saturation at all. You even have to put words into your own source's mouth, it seems.
Curiously all this shows is that you did not read the article.
What this shows is that RAZD cannot even be trusted to copy & paste the portion of the article he talks about. This is particularly deceptive, as RAZD presented the quotation, and then proceeded to misrepresent it. His remarks started "In other words..."

If this were an honest mistake, he was free to acknowledge it. He chose to pretend it was all in order. Anyone who doubts can scroll up and see. And enemies of truth will no doubt claim I'm making this up. Again, I'm thankful for scroll bars & no edit policies.

Polonium Halos Explained

The formation of granite by replacement of solid rocks means that Gentry's theory is no longer tenable. He can no longer legitimately say that Po-halo-bearing granites must form by supernatural means.

Solid diorite and gabbro rock, which had previously crystallized from magma, has been subjected to repeated cataclasis and recrystallization. This has happened without melting; and the cataclasis provided openings for the introduction of uranium-bearing fluids and for the modification of these rocks to granite by silication and cation deletion.

In uranium ore-fields the extra uranium provides an abundant source of inert radon gas; and it is this gas that diffuses in ambient fluids so that incipient biotite and fluorite crystallization is exposed to it. Radon (222Rn) decays and Po isotopes nucleate in the rapidly growing biotite (and fluorite) crystals whence they are positioned to produce the Po halos.

The whole process of Po halo formation can be accomplished without calling on a Creator to do it. The serendipity that has emerged from these observations implies that Po halos in myrmekite-bearing granite indicate a non-magmatic origin for the granite. The argument comes full circle when it meets Gentry's initial [truthfully made] observation that magmatically-derived granites cannot contain Po halos: the half-lives of the Po isotopes are simply too short.
See? Not test at all.

Dr. Gentry has challenged anyone to produce polonium halos by any means, and nobody can do it. Radon and the granites are in no short supply. If the grand fantasy were true, one could just find some fractured sample and pump a little radon through it. Of course this won't even come close to working, and everyone who knows the first thing about decay knows it.

Now let me repeat my comment that you said was "Not what he said. Not even close, and the text's right there for everyone to see."

So how about you renounce evolutionism & call me stupid & save some time? Deal?
Curiously I don't call people stupid. Nor would validation of polonium affect evolution.
Maybe not with words, but such affronts to intelligence amount to the same thing.

You even include one in this comment. You have more than once claimed polonium radiohalos are used to support a young age of the earth, even after I corrected you. Were this true, they'd certainly have quite an impact on all forms of evolutionism, without exception.*

Quote
Polonium is debunked as evidence of a young earth (once again), and meanwhile you still need to deal with uranium halos and the evidence for an old earth.
See? There you go again. Of course contradicting yourself in such a short span, that's not the same as calling everyone "stupid" is it?

Presenting evidence, time and time again, that directly and obviously demonstrates your claims cannot be true, that's not "calling people stupid"? Putting false words in others' mouths, when we all have scroll bars?

Let me help, if I can. You don't have to post every thought that comes into your head. You can evaluate them.

* Allow me to mock in advance this response, and thereby deter you from typing it, or an equivalent. "Um, duh, whun I said 'evolution' I was just talkin' 'bout change. Normal, everyday change. The kind that has nuthin' to do with the debate. This just shows that yur ignorant 'bout what 'evolution' means."

Well, in the context of a debate forum, using a term that's identical to one of the terms which is subject to debate while intending it to mean something that isn't subject to debate is deceptive. Also deceptive, is claiming one meaning for a term, and later substituting another. If you mean 'change', you should say "change". Assuming you want to be honest (and I must admit this assumption runs counter to many an observation.)

This is something that could go in a few different threads. I'm guessing this one's best in the long run.

...and it's funny.

Wiki gets edited left & right these days, with indecisive evolutionists running the show. Here's what the link currently says. (My focus here is on the tail)
Quote
Robert V. Gentry studied these halos and concluded that the rock must have formed within three minutes if the halo was formed by Po-218. This is taken by some creationists as evidence that the earth was formed instantaneously. Other creationists, including some fellow Seventh Day Adventists, have disparaged his work, and have "accused him of willfully ignoring pertinent evidence and of inconsistently and arbitrarily assuming nonuniform decay rates for all radioactive isotopes except polonium."[14]

Critics of Gentry from within the scientific community have pointed out that Po-218 is a decay product of radon, which as a gas can be given off by a grain of uranium in one part of the rock and collected in another part of the rock to form a uraniumless halo. Gentry's examples rely on a radon ring that is close to the Po-210 ring and it is a bit difficult to tell them apart, and it is not certain whether the rings can be positively associated with polonium.[15]

Gentry's work has been continued and expanded by the creationist R.A.T.E. project that was operating between 1997 and 2005. Radiohalos were studied as part of the R.A.T.E. project by creationists such as Andrew Snelling of Answers in Genesis, Russell Humphreys, John Baumgardner and Steven A. Austin at the Institute of Creation Research as well as others at the Creation Research Society.[citation needed] However, Lorence G. Collins, J. Richard Wakefield and others have repeatedly and soundly rebutted the radiohalo evidence for a young earth in peer-reviewed publications.[citation needed]


We've taken a look at Professor Collins' "sound rebuttal", but I was curious about this J. Richard Wakefield.

Found his article at NCSE. . Ready for the funny part?
Quote
About the Author(s):
J. Richard Wakefield is a professional firefighter for the city of Scarborough, Ontario, Canada, and an amateur geologist. He studied zoology at the University of Toronto and has been studying creationism since 1983.

I won't bore you with shredding the article in detail. Most of his argument is not in dispute. We already know that evolutionism has different conclusions about the age of the earth and the "layers" found on the surface. That Genty does not agree with "the mainstream" isn't surprising and it isn't news. What the author needed to demonstrate was that Gentry's ideas are flawed as a "young" earth interpretation.

If one takes all the "old earth" interpretations of evidence as correct, one will disagree with Gentry's conclusions. The author demonstrates this pretty convincingly.

He throws in some junk about Gentry misidentifying rocks. At least some of the time he agrees with the identifications, and I haven't taken the time to sort through his accusations. I know others have found the same kind of radiohalos in granite.

He also tries to use "appearance of age", an argument so flawed that if arguments were living things it would've been stillborn.

His logic is obviously bad in one place.

This deposit has some features characteristic of the metasomatic replacement deposits in marble, of the hydrothermal calcite-apatite-fluorite vein deposits, and of intrusive carbonate deposits. Its mode of origin is in dispute.

The coarse pegmatite crystallization of the calcite, black mica, hornblend, and albite suggest crystallization from a fluid medium, rich in volatiles. . . . The wall-rock alteration, involving addition of fluorine, carbon dioxide, and soda into the surrounding wall-rock, favours crystallization of the [calcite vein dike] body from a fluid state, such as a carbonate intrusive or hydrothermal solution. . . .

. . . The irregular replacement of the wall-rock gneiss and the long relic bands of biotite amphibolite in the [calcite vein dike] indicate metasomatic replacement of the wall-rock gneiss by [carbonatite].

The author believes that the [calcite vein dike] has originally been largely derived from marble but that it has been assimilated or desolved and recrystallized from hot solutions rich in fluorine and soda. This would account for the extensive wall-rock alteration and the metasomatic type of replacement of wall-rock gneiss, without disturbance of relic mafic gneiss bands. Such relict bands are incompatible with an origin of the [calcite vein dike] body involving tectonic movement of a marble bed in a plastic state. The author feels that the deposit is therefore best classed as a special variety of the hydrothermal deposit in which the solutions have carried out extensive metasomatic replacement of the wall-rocks.
From this we learn that the calcite vein dikes are intrusive into and thus formed later than the country rock that makes up the formation. They have also altered the country rock.

No. We learn one interpretation of the evidence. We learn that at least one more interpretation exists, and that the matter wasn't settled at the time the report was written.

Pretty bad when they have to cherry-pick which evolutionist interpretations to employ to try to make Gentry look bad, huh?

And the author's conclusion is not that the radiohalos have been explained away.
Quote
Still, we must give Gentry his due. Nothing in geology fully explains the apparent occurrence of the polonium halos as described by Gentry. They do remain a minor mystery in the field of physics. But this does not mean that no explanations are possible or that it is time to throw in the towel and invoke the "god of the gaps."

Funny. He never asks why the radiohalos can't be produced naturally, or even by man, without leaving marks. The reason's pretty simple. The task involves suspending decay, getting the radioactives to gather into a place, and re-activating decay. That's all. As soon as a man figures out how to do these things, he'll know how to make them. As soon as he figures out a just-so story to get them to happen without manipulation, evolutionism will be undebunkable on the basis of simple radiohalo existence. Until then... well, some of us are content to follow the evidence.

Oh, and I'm sure a few creationists would be happy to acknowledge the capacity of nature to turn on and shut off radioactive decay, if it should be clearly demonstrated. It is the religion of evolutionism that insists that sort of thing must not ever be investigated.

That's about enough for now. We could probably discuss a few more things here, if folks are actually interested.

Another copy of the same article can be found. This copy omits the "about the author" part, and includes additional propaganda on other topics.

Ever work a job with a timeclock? Say your shift starts at 8:00, and you punch in at 7:58. What happens? It depends on the policy. Some places want you to punch in at 8:00 on the nose, no matter what. Places with large numbers of workers, and not many timeclocks tend to allow some leeway. 75 people physically cannot clock in on the same clock within a minute, right?

Okay, if you understand that, you understand what a margin-of-error is. The same simple concept applies to all sorts of measurements. A speedometer may be accurate to within 2 M.P.H. A voltmeter may be accurate to with half a volt. Stuff like that.

Why'd I explain that? Because evolutionists don't want you to understand it. If you know what a margin-of-error is, you'll understand that one of their most sacred lies is a lie.

This PDF file contains the information I'll be referencing.

Quote
... For these reasons, the half-life of 92Sr has been measured to solve a recently observed inconsistency with the quoted value in the nuclear data libraries: T1/2 = 2.71 ± 0.01 h. In this work, a new value is proposed: T1/2 = 2.594 ± 0.005 h. A better accuracy is achieved compared to previous evaluations. It also shows a good agreement with the most recent studies: T1/2 = 2.627 ± 0.009 h.

They're trying to determine the half-life of 92Sr. If the new measurement fell within the stated margin of error of the old measurement, one could claim they were simply refining what was already known. They don't. The new measurements are in conflict with the others. If you read the link, they make it pretty clear.

By the standards employed by the authors, and generally by anyone who knows what term 'margin-of-error' means, values with non-overlapping margins-of-error (or 'error bars') are in conflict. You'll see what I mean if you check out the text on the third page, below table four.

Quote
A weighted average from the three values was determined
for each fuel pin. Nevertheless, as the discrepancies were
sometimes beyond their reported uncertainties, the associated
uncertainty is calculated from the standard deviation between
the three values, with a multiplication factor tp(?) = 1.32 [15]
that arose from the low degree of freedom of the sample.

('Uncertainties' is another term for margins-of-error.)

Due to the failure of the margins-or-error to overlap, their conclusion cannot be honestly interpreted as "merely a refinement". It is unquestionably in disagreement with the other values.

Perhaps a different individual wrote the final sentence than wrote the earlier part. One hopes so, because the "good agreement" is actually a clear and unambiguous disagreement..

Also, a 90Sr discussion says
Quote
A recent paper has reviewed methods for the evaluation of discrepant sets of data and demonstrated the results of applying these methods to the published half-life data of 90Sr and 137Cs [MacMahon, T.D., Pearce, A., Harris, P., 2004. Convergence of techniques for the evaluation of discrepant data. Appl. Radiat. Isot. 60, 275-281]. The half-life data for 3H has been subject to a comprehensive review and critical evaluation by Lucas and Unterweger [2000. Comprehensive review and critical evaluation of the half-life of tritium. J. Res. Natl. Inst. Stand. Technol. 105, 541-549].
Bold is mine, above and below.

Later on it says
Quote
...resulting in a recommended half-life of 4497(4) days. MacMahon et al. [Convergence of techniques for the evaluation of discrepant data. Appl. Radiat. Isot. 60, 275-281] highlighted problems in the evaluation of the discrepant half-life data of 90Sr, in particular the worrying upward trend in the data, where the weighted mean of all the measurements increases, on average, by 35 days each time a new measurement result is added.

Is the term "worrying" justified? I believe it is. Fortunately, in the case of 90Sr, nuclear reactor safety issues are involved, so there is a conflict-of-interest vs. evolutionism. How many of these people would be willing to jeopardize the lives of health of strangers for the religion? In spite of intense conditioning, I think eyes may be opening. Prejudice isn't always an effective barrier for holding back truth.

Now what don't we see here? We see reports of different values at different times. We see attempts to analyze the data sets differently. We do not see anyone much asking "what if all the measurements are correct?" The assumption that the rate is constant appears to be preventing this question. What if the assumption is false and the rate is actually changing from measurement to measurement? Who will tell us? The best interpretation of the evidence here is clear and straightforward : the values change. In order to interpret it differently, they'd have to be misstating the margins-of-error.

You'll notice that both of these links are about identifying decay rates with more precision. In 1907, Professor B. B. Boltwood, radiochemist of Yale University, published a list of geologic ages based on radioactivity. Although Boltwood's ages have since been revised, they did show correctly that the duration of geologic time would be measured in terms of hundreds-to-thousands of millions of years. This continues to be the case. In order for the YEC scenario to be true, scientists must be mistaken about decay rates by factors of 100 or more. That's substantially more error than you seem to have been hoping to identify from your links. What's more, those two strontium isotopes are not used in radiometric dating of rocks because their half-lives are very short; these are toxic products of nuclear reactors (SR90 was a product of the Chernobyl disaster).

According to that first study on SR92, it has a spread of 5% between values, and with a half-life of under three hours. That isotope is 1) rare and 2) REALLY HOT to handle. Errors in decay rate measurement for things like carbon-14 will be smaller. Decay rates for isotopes with longer half lives, i.e. those used to date rocks, are known to within a few percent or better. One of the several reasons that U-Pb concordia-discordia dating is so often used is that the decay rate of uranium is known to much better than a percent. Bombs and reactors tend to attract lots of research money.

Some further info courtesy of "JonF", a scientist who talks at EvC:

from Begemann, F., Ludwig, K. R., Lugmair, G. W., Min, K., Nyquist, L. E., Patchett, P. J., Renne, P. R. Shih, C.- Y., Villa, I. M. and Walker, R. J. (2001). Call for an improved set of decay constants for geochronological use. Geochim. Cosmochim. Acta 65, 111--21:
Quote
The decay of 238U and 235U to 206Pb and 207Pb, respectively, forms the basis for one of the oldest methods of geochronology. While the earliest studies focused on uraninite (an uncommon mineral in igneous rocks), there has been intensive and continuous effort over the past three decades in U-Pb dating of more-commonly occurring trace minerals. Zircon in particular has been the focus of thousands of geochronological studies, because of its ubiquity in felsic igneous rocks and its extreme resistance to isotopic resetting.
No decay constant of any radionuclide used for geochronology has been (or, arguably, can be) more-precisely measured than those of 238U and 235U, a consequence of the mode of decay (alpha), favorably short half-lives, and the availability of large quantities of isotopically pure parent nuclides.


Now adding to this, as has been shown in the Geologic Column thread, scientists regularly use more than one dating method in order to verify the accuracy of the dates for the rock samples. The consilience of dates obtained with multiple methods (including U-Pb) using different isotopes with different decay modes is powerful evidence that scientists' dates are correct within a small margin of error.

Let's not forget human corruption.

We live in very corrupt times, and the promotion of evolution by the modern-day crusaders (Rockefeller, Kissinger, etc.) is key to the implementation of the new global socialism (evolution is the basis for socialism). So corruption is a viable explanation for these rock dating anomalies.

I know that you are resistant to the idea of corrupt scientists, but I believe you are becoming in the minority because the evidence shows otherwise.

In these days, it's important that we escape our naivety and realize that very corrupt people have seized the governments of most counties of the world, just as Biblical prophecy demonstrates.

Good point, Russ. Evodates are the only type of "Lab testing" that is never done "blind". The labs are always told what results are desired. The very set-up reeks of dishonesty.

And the excuse isn't even close to plausible. "The equipment is so super-sensitive and expensive it might get broken if we didn't know what results to expect". Total bunk! Other labs have super sensitive equipment which is very expensive, yet they operate honestly in this respect.

What's more, they're saying, in effect, that they're risking the equipment on a regular basis: a simple typo on a submission form, or misplacement of a decimal point would destroy it, right? And humans do make such mistakes all the time. There are lots of other errors involved "in collecting samples" which lead to "erroneous results", and they also happen all the time. How many evodate-generating machines have been destroyed over the years?

Evodates amount to evolutionists saying "trust us". We've seen their integrity fail enough times that there is no basis whatsoever upon which to build such faith. The most appropriate response to such a request is an healthy guffaw.

'About' is a subjective assessment. Objectively, both links report changes in decay rates, something evolutionists claim is impossible.

The rest of your post does not address this fact. Either you miss the point, or you desire to divert attention.

You want folks to think the half-lives used to generate evodates have been investigated more thoroughly. If this be the case, someone has some screwed-up priorities indeed! Disputing Genesis is more important than nuclear reactor safety? I cannot argue that people who think that way don't exist - I've seen too much quackery, pride and selfishness. One hopes they're few in number.

Obviously "identifying decay rates with more precision" is not the same as "saying decay rates have changed." And yet scientists have identified the decay rates used in radiometric dating of rocks to a few percent or less. Unfortunately for you, the enormous error rate required by the YEC scenario is not a reality.

Sorry but wrong. "Blind" tests are in reality rarely done because a) a good scientist will have some idea of the provenance of the rock sample and b) it costs a lot of money to keep trying different dating methods, hence a). But that isn't to say that you couldn't go on a blind date if you wanted to. If you were really interested in finding the age of a sample with no prior information, you do it with several methods and you do them on individual minerals separated from the rocks. Then if the methods agree you almost certainly have a good date.

In the real world, of course, you essentially always do have prior information.

The K-Ar method (and almost all radiometric methods) boils down to measuring a quantity of stuff. (The best methods actually measure the ratio between the quantities of two different stuffs, and then use other information about the quantity of one to calculate the quantity of the other.) When a rock is old, there's a lot of stuff to measure. When the rock is young, there's not much stuff to measure. A K-Ar lab will start by cleaning as much previous sample material and argon from the equipment as is feasible. (If you tell them you think your sample is relatively young, they will take extra care in the cleaning process. And charge more.) Then they will measure your sample and the readouts will tell them there's Y amount of argon.

Every few runs they will run the equipment with nothing in the sample holder. The readouts will say there's a non-zero amount of argon, call it X, which they can calculate as being equivalent to an age of Z years.

If the amount they measure in your sample, X, is pretty much equal to Y, then they will report the age as Z years or less. If X is greater than Y they will report an age older than Z with appropriate error bars. If X is less than Y they will try to figure out what's going on. Add to this the fact that the K-Ar method is simply unsuitable for very young rocks. In essence, if you submitted a sample of young rock for K-Ar dating, you would get a result back that says something like <100,000 years, in which case you try a different method more suitable for young rocks.

I find myself having to repeat the same thing as always: don't criticise things you don't understand. Don't you think that's a sensible rule of thumb? Like, cherry-picking articles from scientific journals on nuclear physics for words like "inaccurate" and "discrepancy", when the people who wrote those articles and those who reviewed them for the journals know a little more about the topic than you?

That's not a word game at all. There is a big difference between subjective and objective matters. Your assessment was a subjective red herring.

(Now for those who are exclusively emotional, the objective may seem invisible. I grant you that much.)

These reports also demonstrate the reluctance of real-world scientists to challenge evolutionism's sacred cows. This is another issue that will allegedly win a Nobel Prize for anyone who can demonstrate it. Decay rates change. Why aren't these folks proclaiming the news for all its worth and campaigning for their rewards? We're told there's nothing they'd love more than to overturn the dogmatically-held beliefs, so why aren't they doing it? Guess that's just one more piece of patently false propaganda...

Decay rates change. That's reality. Now either close your eyes and go on like you never found out, or start dealing with the truth. What'll it be?

Blind tests are done as standard procedure in ALL FIELDS of REAL SCIENCE. This is because that's SO obviously the most scientific and honest approach. Scientists in other fields aren't all idiots; they know what they're expecting in most cases, and many of their tests have costs as well.

This practice is unprecedented and inexcusable. It doesn't take a genius to figure out why it's done the way it is; on the contrary, it takes a willfully naive victim to believe it has any merit at all.

I think I see now -- you're claiming that scientists have to re-define decay rates because you think decay rates change.

I've got a lot of information to share with you as to why this is not the case. Should I start now, or would you like to present any information yourself first? All the two studies you linked to show is that decay rates are being defined with more precision. Maybe you can start by explaining how exactly you think decay rates changed in the past or are changing now. I'll warn you that you'll have to be prepared to deal with some science.

Did I say that it's never done in radiometric dating? I even explained to you how you could go do it.

You seem to be deeply mistaken here. While there are some exceptions, generally you can use any kind of method that works for the age of the rock and perform it as many times as you want, using different laboratories if you like, since that can work as a good control. (You really didn't look at any of those links I posted did you.) You can also date individual minerals in the rocks. What's more, lava can also contain xenoliths, which are impurities that did not fully melt and whose isotopic clocks have not been reset. You have to remove these or you will get a false old age for the rock. Creationists trying to "prove" that radiometric dating gives dates which are way too old, such as Steve Austin, have been known not to separate the xenoliths from their samples -- a "mistake" no honest geologist would make. It's quite easy to date a xenolith and a pure sample separately.

Both my links show clear and undeniable changes in the rates of decay. One shows changes in the decay rate of 90Sr, and the other shows changes in the decay of 92Sr. Can you read or not?

By your requirement for honesty, a scientist who wants the sizes of trees in a forest shouldn't tell the people doing the measuring what is to be measured because they would then have some idea what size it is.

And the excuse isn't even close to plausible. "The equipment is so super-sensitive and expensive it might get broken if we didn't know what results to expect". Total bunk! Other labs have super sensitive equipment which is very expensive, yet they operate honestly in this respect.
Can you provide an example of a lab that performs measurements on something without having some idea of the scale of the measurement to be encountered?

Quote
What's more, they're saying, in effect, that they're risking the equipment on a regular basis: a simple typo on a submission form, or misplacement of a decimal point would destroy it, right?
Who claims they are risking equipment?

I can read and neither paper claims that the decay rate changed. Both claim that it was imprecise measurements or failure to account for all variables that caused the previously posted rates to be incorrect. Why do you agree with the scientist's measurements yet disagree with their conclusions especially since the new measurements are the result of accounting for the variables that they claim caused the incorrect measurements?

At least that is what I understood from the papers you presented. Perhaps you could quote places in the paper that show my understanding of them to be incorrect.

Baloney! The most you'll generally see is two kinds of tests, perhaps three on any sample. The rock has to contain the Ar or the U or whatever other chemical you're looking for. Many don't contain any of them.

I missed the comments about lab equipment that Linear picked up. Talk about coming from left field. There's always a small residue left on the equipment when it has been used for radiometric dating. It's simply very expensive and time-consuming to give it a thorough clean before each new test. You can pay for this if you have, using the example I gave, a relatively young sample for K-Ar dating. Or, much more typically, if your sample for this method is likely to be older, the error introduced by the residue on the equipment is going to be small. This is because there's going to be a lot more argon in an old sample so the argon contamination on the equipment won't make much difference to the result. This has got nothing to do with equipment being fragile or whatever else you claimed.

Another question is why you're so insistent that a blind study be done in radiometric dating. This isn't like medical studies where the double-blind procedure is suitable. Like I explained to you, if you take a rock sample and the method you've used gives you a result that is less than or greater than the age range that the method can date, you try other methods. Date your sample several times; use other suitable methods and different labs. If you get a consilience of dates then you can be reasonably certain that you know how old your rock is. How do you think that this process, which is time-consuming and expensive, would be any more revealing than dating a rock you have more information about? Scientists still date samples several times, use other suitable methods and different labs.

Quote

And if there is consilience between those dates, you can be reasonably certain that you know the age of your rock. Just how many tests would you personally want to see done before you were convinced? Ten? A hundred? I'll hazard a guess: even an infinite number would still be dismissed by you because you don't want to consider the possibility that the earth is old.

Quote
You can't run a test for chemicals that aren't in the sample.


Okaaaay . . . so the dates that you see from the application of methods such as K-Ar or U-Pb mean that those elements were in the samples. Problem with this?

Quote
'Routinely' to the rest of us means most of the time - not 5 or 6 per cent.


Well I can't help the fact that you're not a practising scientist and that you won't look at the relevant literature. Yes, scientists actually are interested in getting accurate results and will put controls in place to make sure they do, which often means doing multiple tests. There are many studies on the internet that a simple Google will find for you. I've provided you with some summaries of their results in this thread.

Quote
What makes you think I haven't?


Let's see . . . maybe it's the rest of this comment that says "looking up hype." You're taking the same tack as Russ: dismissing a summary of dozens of radiometric studies published in peer-reviewed journals. I linked you to two of these. This one is for moon rocks. Each sample was dated by at least two methods. Most samples have been repeatedly dated in separate studies years apart by different scientists, using the same or different methods. Note also that though the samples were taken from different areas (depending on which mission collected the samples), the whole list of ages is in close agreement. This suggests that the lava which formed the mare areas on the moon was a large, more or less concordant event that happened quite a long time ago.

We'll perhaps leave your "you don't understand creation science" oxymoron for another thread. I understand it enough to realise that it's wrong about the age of the earth. It seems to be struggling at the moment to provide evidence for a global flood as well. You've had quite a lot of time now to post your masses of evidence here but you seem to instead spend most of your time saying that evolutionists lie. You are not to blame though because this is what creationists generally have to do to cover the fact that in reality their only source of "evidence" is the Bible. They have no dating methods of their own do they?

You're funny. I told you not long ago that scientists had begun studying radioactive decay more than a century ago (heard of the Curies?). By your own reasoning, because the estimates then or at other times in the past are not the same as the estimates today using modern equipment, the decay rates have changed by the difference between the estimates. This is about as logical as saying "When I measured this grain of sand with a ruler, I estimated that it was so big; now that I'm looking at it in a microscope, I get a different estimate. OMG, the sand grain changed its size!!!"

Now there are a number of reasons why we can be reasonably sure that radioactive decay rates have not changed. You have said you don't like to have to deal with lots of evidence all at once, so I will start with one piece of information from astronomy, which happens to be one of my favourite branches of science.

SN1987a was a supernova that exploded in the Large Magellanic Cloud, a satellite galaxy of the Milky Way -- right next door by cosmic standards. Its distance from the Earth can be measured by trigonometry. Theory predicts that such a supernova would create about 0.1 solar masses of nickel-56, which is radioactive. Nickel-56 decays with a half-life of 6.1 days into cobalt-56, which in turn decays with a half-life of 77.1 days. Both kinds of decay give off very distinctive gamma rays. Analysis of the gamma rays from SN1987a showed mostly cobalt-56, exactly as predicted. And, the amount of those gamma rays died away with exactly the half-life of cobalt-56. For more details, read Radioactive Decay Lines from Asymmetric Supernova Explosions; or a more general read for the layperson, Variable Stars.

Since SN1987a was 170,000 light years away we were seeing light generated 170,000 years ago. This means that radioactive decay ran at the same speed 170,000 years ago as it does now. Simple and elegant, no?

I'm reporting this outright lie to Bex and Russ.

Either you misrepresent yourself as one who read the information, or you misrepresent the measurements as being old. In any case, you have grossly misrepresented my position.

The measurements in those studies are all modern, using state-of-the-art equipment and methods. The margins-of-error are duly noted.

Because you don't want to admit the truth (or even simply shut up) this is what we get. You clearly demonstrate that you do not intend to participate honestly. No doubt whatsoever - none - zero exists in my mind. If your goal is to disgust people, congratulations.

They report changes in measured rates. This is data. It's simple and easy to understand.

No they don't.

Why do you agree with the scientist's measurements yet disagree with their conclusions
The measurements are measurements - what's to disagree with? The conclusions are reached by assuming the rates cannot change. There's no other way to reach that conclusion.

Quote
especially since the new measurements are the result of accounting for the variables that they claim caused the incorrect measurements?
Simply untrue. They took fresh, new measurements.

I'm reporting you as well. I missed your posts before, but apparently someone's following your lead.

The margins-of-error are reported, and are right there for everyone to see. Saying it's a matter of imprecise equipment doesn't cut it, and you'd know that if you actually read the pdf.

Quote
At least that is what I understood from the papers you presented. Perhaps you could quote places in the paper that show my understanding of them to be incorrect.
At least that's what you think you can bluff the readership into believing. I've about had it with the blatant dishonesty game.

The reports clearly state that different results were obtained at different times, using modern equipment and techniques. The discrepancies are larger than the margins-of-error. There is no reasonable interpretation other than to admit the rates were different. None whatsoever. Evolutionists would like to pretend the margins-of-error overlap. Then you could say it's a matter of equipment or technique. The margins don't overlap. It's simple, clear observation.

I'm closing this thread for now. You're as transparent as the other one.

Okay, the problem has been resolved; LindaLou and LinearAq are no longer allowed to post in this area.

Myself, I'm going to take another stab at explaining margins-of-error. If folks are still having trouble understanding things, there's a good chance it's because of the '±' sign involved in the notation. It's not very big on my screen, so here it is again '±'. It just means "plus or minus". Sometimes it's written '+/-'. So 63 +/- 1.5 means a value which must be between 61.5 and 64.5, and could be any value withing that range, get it? It's how they say "give or take", and communicate how much one is permitted to give or take when employing a given piece of equipment in a given manner.

Why has it come about? We don't have tools which will allow us to measure physical things perfectly, with infinite precision. The very lines on a ruler do themselves have a length. You might measure something and say something is 1 cm long, but can you say with scientific certainty it isn't 0.0001 cm shorter or longer? Not with a typical ruler, even using a magnifying glass.

Scientists acknowledge the imperfections of their measurements. One of the most common acknowledgements of inaccuracy is found in advertisements for watches and clocks. Ever seen claims like "accurate to within 3 seconds per year"? Well, that translates, at the end of a year to 1 year ± 3 seconds; after 2 years it'd be ± 6 seconds.

A good deal of effort goes into establishing margins-of-error. They're pretty important. They're certainly not "pulled out of thin air". Let's try it out on, oh say a number like 292.6441 ± 0.0012. What's that mean? It means a measurement was made, and the actual value could be anywhere from 292.6429 to 292.6453. See how that works?

Now if a second measurement of the same thing comes in at 292.6449, the two measurements agree because the second value falls within the range permitted by the first. Even when the centers of the ranges disagree, if there's any overlap, the measurements are considered to be in agreement. "12 ± 2" agrees with 16 ± 2" because both overlap at 14. Of course 27 ± 3 is not in agreement with either of those, because the lowest value it permits is 24 and 24 is outside of the range of the other measurements.

Now different methods of taking measurements will have different margins-of-error. When a method is improved, and becomes more accurate, the margin-of-error shrinks. The notion that this invalidates the old measurements isn't found in science. The old measurements are still considered accurate within their larger margins-of-error.

This is just common sense. Take track records in racing for example. Are old records thrown out every time a new timing device is introduced? Does anyone consider them invalid? Certainly not. If the record on a track is 4 minutes and 17.22 seconds, set in 1971, that's the record everyone still has to beat even if the new timing equipment is accurate to 1/100,000 seconds.

Now nowhere in either of my links was it suggested that the margins-of-error involved in the previous measurements were too small. Nowhere was it suggested that those who took the measurements made mistakes. A refinement in one technique was discussed, which resulted in improved accuracy. Know what? This improved accuracy shows right up, just the way any scientist or thinking person would expect it to show up: the margin-of-error is smaller.

So much for tossing aside the inconvenient earlier measurements - it's not scientific; and it's not advocated in either report.

Every bit as inexcusable, for anyone who claims to have read the report, is the false idea that the "new" measurements somehow match. (The "old" measurements were from 1971 - not "more than a century ago (heard of the Curies?)")

The authors of the 92Sr pdf report obtaining fresh new results of decay time measurements which do not match up. Table four lists the measurements, and right beneath table four, it says
Quote
A weighted average from the three values was determined for each fuel pin. Nevertheless, as the discrepancies were sometimes beyond their reported uncertainties, the associated uncertainty is calculated from the standard deviation between
the three values, with a multiplication factor tp(?) = 1.32 [15] that arose from the low degree of freedom of the sample.
"Discrepancies were sometimes beyond their reported uncertainties" means they took measurements of values, and the measurements did not match, even allowing for the inaccuracy of the method. Plain as can be. It doesn't get any simpler than that.

Now as to the question of what to make of it, there are two approaches. One can look and see here's a measurement, and here's another measurement; since they disagree I conclude a change took place.

Or one can assume change is impossible, and misinterpret things based upon that assumption. Likewise one can assume any wrong idea one prefers, and misinterpret things 'til doomsday. "Racial" supremacy, heliocentric universe, and flat earth can all be "proven" by stubborn, steadfast assumption and refusal to properly address evidence. A technique which can potentially prove anything true, even that which isn't, is irreconcilably opposed to all scientific endeavour.

Add to this technique a willingness to make false claims about the content of links and the very nature of the evidence being discussed, and you get... goodbyed.

Those who would take a better approach are always welcome to participate here. I know evolutionists exist who don't routinely misrepresent arguments and evidence, and I'd like very much to have more positive evidence of their existence to present to my fellow creationists. ...And to the run-of-the-mill evolutionists, for that matter.

A correlation has now been established between seasons and the sun, and at least some of the observed fluctuations in rates of decay.

Makes the fluctuations much more difficult to dismiss, don't you think?
