Fossil succession and the geologic time scale are constrained by the observed order of the stratigraphy -- basically geometry -- not by evolutionary theory.

The number of dates that disagree with the expected ages is not insignificant. It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for "young Earth" theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.

He believed this even though he did admit that some heat might be generated by the tidal forces or by chemical action.

One way is to find yearly layers that are produced over longer periods of time than tree rings. Because there was great diversity among the rates assumed, the range of estimates was also large—from a high of 2.

Geological Association of Canada, Special Paper 39, p. It demonstrates how consistent radiometric data can be when the rocks are more suitable for dating.

Techniques for radioactive dating have been tested and fine-tuned on an ongoing basis since the s. Specifically, he proposes an age of Some of these are taken from John Woodmoreappe's article on the subject, but only when I have reason to believe the statements are also generally believed.

Some of these events do exist. Some gave virtually zero ages, although the geologic evidence suggested that devitrification took place shortly after the formation of a deposit.

We are told that these methods are accurate to a few percent, and that there are many different methods.

Nonradiometric dating

Henke further states in his reply to me, Dickinp. The geological time scale and the techniques used to define it are not circular.

A Geologic Time Scale, Radiometric dating example problems. Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records. TL dating and its related techniques have been cross calibrated with samples of known historical age and with radiocarbon and thorium dating.

However, note that because of the " principle of cross-cutting relationships"careful examination of the contact between the cave infill and the surrounding rock will reveal the true relative age relationships, as will the "principle of inclusion" if fragments of the surrounding rock are found within the infill.

In general, the dates that are obtained by radiometric methods are in the hundreds of millions of years range. Boltwood focused on the end products of decay series.

Especially the gaseous radioactive decay byproducts such as argon, radon, and helium are mobile in rock. For more on this subject, see the video Bones in Stones.

There are situations where it potentially fails -- for example, in cave deposits. Potassium volatilizes easily, is easily leached by water, and can migrate through the rocks under certain conditions. Lubenow's work is fairly unique in characterising the normal scientific process of refining a difficult date as an arbitrary and inappropriate "game", and documenting the history of the process in some detail, as if such problems were typical.

The data do not support such an interpretation.
