Aerial radiometric and magnetic reconnaissance survey of portions of Arizona, Idaho, Montana, New Mexico, South Dakota and Washington. Volume 2-G. Butte Quadrangle. Final report
The results of a high-sensitivity, aerial, gamma-ray spectrometer and magnetometer survey of the Butte Quadrangle, Montana, 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 74 anomalies worthy of field checking as possible prospects. Thirty-nine anomalies are associated with Precambrian quartzites and argillites that may contain uranium-rich veins. Other vein-type uranium prospects may be the causes of 20 preferred anomalies related to Cretaceous and Tertiary igneous rocks, particularly the eight anomalies associated with the Boulder batholith. Sandstone-type deposits may be indicated by 18 preferred anomalies in Cretaceous and Tertiary sedimentary rocks and 18 in Quaternary units. Many of those in the Quaternary may be caused by uranium-rich source rocks. Anomalies that may reflect the presence of deposits similar to the Blind River and Rand may be associated with Cambrian quartzites. Several preferred anomalies in the Butte Quadrangle may be caused by this type of deposit. One anomaly may indicate the presence of a phosphate deposit with possible by-product uranium.
