It was moderated by water permeating a deposit of uranium.

It needs to be stressed that the RATE group recognises that there is physical evidence in the rocks that massive amounts of radioactive decay have occurred through the earth's history, and that there is a systematic trend in the radioisotopic 'ages' of the rocks in the geologic record from oldest at the bottom to youngest at the top.

However, there are many anomalies and there is much evidence of radioisotopic inheritance and mixing because of global tectonic processes having stirred the mantle and added magmas to the crust, which has likewise been stirred by the crustal rock cycle.

Interestingly, using these sorts of ratios, one piece of moon rock dated as being 8.2 billion years old, to the amazement of the dating laboratory involved.

As far as stars are concerned, the Th/Nd ratio has been shown to be unchanged no matter what the age of the star is, which leads one to two conclusions.

It is through this mechanism that the radiometric age of the universe is usually calculated as being on the order of ten billion years.

Professor Fowler did exactly this and has maintained his calculated radiometric age for the universe at about 10 billion years, with which I am basically in agreement.This then suggests that the majority of the elements were formed at the beginning rather than through a series of supernovae explosions.Given that point, it seems that the stars must be basically the same age.As the reaction would proceed, the water would heat up and vaporize, thereby depriving the neutrons of the moderating influence of liquid water, and the reaction would slow down.As the water vapor condensed and reformed, the reaction would pick up the pace again.This didn't last very long on a geological time scale, but the reaction results are very informative.
