Description

From Introduction: "The Pocatello 1º x 2º Quadrangle, Idaho (Fig. 1), was evaluated to identify geologic environments and to delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments were evaluated primarily on the basis of surface investigations, because only limited subsurface data were available."

Notes

Abstract: The Pocatello 1° x 2° Quadrangle, Idaho, was evaluated to identify and delineate areas containing geologic environments favorable for the occurrence of uranium deposits to a depth of 1500 m, using criteria developed for the National Uranium Resource Evaluation program. General surface reconnaissance, radiometric traverses, and geochemical sampling were conducted in all accessible geologic environments within the quadrangle, and subsurface data were evaluated. Aerial radiometric data were evaluated, and anomalies located and investigated. Known uranium occurrences were examined in detail and several new occurrences were identified. Environments considered favorable for uranium deposits are Tertiary lignite-type deposits in the southwestern part of the quadrangle. The Albion Range, including the Conner Creek area and the area south and west of the City of Rocks, was identified as an environment favorable for anatectic and vein-type uranium deposits in metamorphic rocks. The City of Rocks area is favorable for pegmatitic uranium deposits. Several areas where low-grade deposits of uranium may be found were designated unfavorable. These are the aplitic segregations of the Almo Pluton and the Tertiary tuffaceous sedimentary rocks of the Salt Lake and Starlight Formations. The thick deposits of the Salt Lake and Starlight Formations in the deep sedimentary basins, pegmatitic and metamorphic environments in buried intrusives, rhyolitic rocks beneath the basalts of the Snake River Plain, basin and range fault environments, and placer deposits adjacent to the Almo Pluton were unevaluated because of the lack of subsurface data. The area of the Fort Hall Reservation was unevaluated because permission for access was not granted.
