Notes

Abstract: The Lemmon Quadrangle was evaluated to identify and delineate geologic environments favorable for the occurrence of uranium deposits using criteria developed for the National uranium Resource Evaluation program. Surface studies included investigation of uranium occurrences, general surface reconnaissance, and detailed rock sampling in selected areas. In addition, followup studies were conducted on carbone spectrometric, aerial radiometric, and hydrogeochemical and stream-sediment surveys. Subsurface investigations included examination of geophysical well logs and ground-water geochemical data. These investigations indicate environments favorable for sandstone-type uranium deposits in the Upper Cretaceous strata and lignite-type deposits in the Paleocene strata. Environments unfavorable for uranium deposits include Tertiary sandstones and Jurassic and Cretaceous strata, exclusive of the Upper Cretaceous sandstone.

Includes microfiche (9).
