Description

Thorium and uranium abundances in sedimentary rocks increase at the Archean-Proterozoic boundary, in response to an episodic change in the composition of the upper continental crust. Uranium decreases and Th/U increases during post-Archean time due to significant recycling of sedimentary rocks. (author)
