Of course there seem to me to be fairly reasonable explanations for this observation which may allow for more slowly forming granitic rocks.

For instance, polonium radiohalos are sometimes associated with polonium bands generated by the polonium being transported by hydrothermal fluids along fractures.

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.

As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.

In short, the assumption that decay rates are immune to outside influences isn't as solid as it once appeared to be.

However, if one does assume a constant decay rate, and if one starts with an originally pure sample of “parent element,” then the proportion of parent to daughter tells us the number of half-lives, which has been used to find the supposed age of igneous rocks. The conclusions of Renne and his team read as follows: Ar can be identified in volcanic sanidine, and while perhaps negligible in pre-Holocene rocks, it has important consequences for sample at the limit of the method’s applicability.

Chamberlain (1899) pointed out that Kelvin's calculations were only as good as the assumptions on which they were based.

"The fascinating impressiveness of rigorous mathematical analyses, with its atmosphere of precision and elegance, should not blind us to the defects of the premises that condition the whole process.

Of course, later scientists, like John Perry and T. After this came to light, Kelvin admitted that he might just as well have set his original upper limit on the age of the Earth at 4,000 Ma instead of 400 Ma.

Of course, this was a close as Kelvin ever came to publicly recanting his position.

Of course, the detected variation is no more than 0.2% of the published rates, but this paper is still quite interesting since such a correlation was never suspected before.

If magnetic fluxuations or other influencing forces are strong enough, *radiometric* decay rates could be much more significantly effected.

Later, after radioactivity had been proven to be a significant source of the Earth's internal heat, he did privately admit that he might have been in error.
