Radioactivity And Geology An Account Of The Influence Of Radioactive Energy On Terrestrial History PDF Download

Excerpt from Radioactivity and Geology, an Account of the Influence of Radioactive Energy on Terrestrial History To these laboriously detailed observations upon the rocks the more generalized ones upon the radioactivity of the ocean have to be added. In its waters and its sediments we are presented with the age-long accumulation of materials arising from the denudation of the primary rocks. Thus the oceanic radioactivity testifies to the world-wide presence of uranium in those surface materials which, throughout the whole of geological time, contributed substances to the seas. When, finally, we compare the results on impoverished detrital sediments with those on the igneous rocks, we find their joint evidence in harmony with that yielded by the ocean.
