Interweaving the relative time scale with the atomic time scale poses certain problems because only certain types of rocks, chiefly the igneous variety, can be dated directly by radiometric methods; but these rocks do not ordinarily contain fossils.

Some, like Robert Gentry, have even argued that Radio-halos from rapidly decaying radioactive isotopes in granite seem to indicate that the granites were formed almost instantly.

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

However, on the whole, he thought that these sources were not adequate to account for anything more than a small faction of the heat lost by the Earth.

In other words, the decay rates show annual changes that closely reflect the Earth's distance from the Sun (see illustration).

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.

What is especially telling about this whole story is the conclusion of the absolute truth of the conclusion based on premises that are weak, or at least not adequately demonstrated.
