Aerial radiometric and magnetic reconnaissance survey of portions of Arizona, Idaho, Montana, New Mexico, South Dakota and Washington. Volume 2-K. Hot Springs Quadrangle. Final report
The results of a high-sensitivity, aerial, gamma-ray spectrometer and magnetometer survey of the Hot Springs Quadrangle, South Dakota, are presented. Instrumentation and methods are described in Volume 1 of this final report. This work was done by Texas Instruments Incorporated under Bendix Field Engineering Corporation Subcontract No. 78-184-L as part of the US Department of Energy National Uranium Resource Evaluation (NURE) Program. Statistical and geological analysis of the radiometric data revealed 132 uranium anomalies worthy of field-checking as possible prospects. The rocks in this quadrangle register eU/eTh ratios significantly higher than normal rock types. Six anomalies associated with Precambrian rocks of the Black Hills may be indicative of vein-type uranium deposits. Paleozoic rocks ranging in age from Triassic to Mississippian contain 11 anomalies that may indicate uranium prospects in limestones. Most anomalies in this quadrangle are in units that contain bentonite. Six anomalies are associated with the Cretaceous Fall River and Lakota formations, 13 with the Cretaceous Niobrara near th contact with the Pierre Shale, and 38 with the Tertiary White River Group. Sandstone-type uranium deposits may be indicated by three anomalies in Jurassic rocks and eight in the Arikaree Formation. Anomalies related to Quaternary units may indicate the presence of uranium-rich source rocks that could host uranium mineralization.
