A study of uranium favorability of Cenozoic sedimentary rocks, Basin and Range Province, Arizona: Part I. General geology and chronology of pre-late Miocene Cenozoic sedimentary rocks

Abstract

This study focuses attention on Cenozoic sedimentary rocks in the Basin and Range Province of Arizona. The known occurrences of uranium and anomalous radioactivity in these rocks are associated with sediments that accumulated in a low energy environment characterized by fine-grained elastics, including important tuffaceous materials, and carbonate rocks. Most uranium occurrences in these rocks appear to be stratabound.
