National Uranium Resource Evaluation: Kingman Quadrangle, Arizona, Nevada, and California

Literature research, surface geologic investigations, and rock sampling were conducted for the Kingman Quadrangle, Arizona, Nevada, and California, to identify geologic environments and delineate areas favorable for uranium deposits. Favorability criteria developed during the National Uranium Resource Evaluation program were used. The studies were augmented by aerial radiometric and hydrogeochemical and stream-sediment surveys. No environments favorable for uranium deposits of at least 100 tons U/sub 3/O/sub 8/ were found. Unfavorable environments include all sedimentary, igneous, and metamorphic rocks of Precambrian to Laramide age; Tertiary volcanic sequences; and Quaternary caliche. Unevaluated environments include the Bird Spring Formation and the intermontane valleys.
