Aerial radiometric and magnetic reconnaissance survey of portions of Arizona, Idaho, Montana, New Mexico, South Dakota and Washington. Volume 2-A. Cut Bank Quadrangle. Final report

Technical Report ·
OSTI ID:6083884

The results of a high-sensitivity, aerial, gamma-ray spectrometer and magnetometer survey ofthe Cut Bank Quandrangle, 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. 78-184L as part of the US Department of Energy National Uranium Resource Evaluation (NURE) Program. Statistical and geological analysis of the radiometric data revealed 40 uranium anomalies worthy of field-checking as possible prospects. Eight anomalies are associated with Precambrian quartzites, argillites, and limestones in the Northern Rockies physiographic province. One anomaly in this province is associated with Cambrian rocks and may be caused by uranium prospects in the Flathead Quartzite. In the Great Plains physiographic province, the presence of possible sandstone-type uranium prospects is indicated by thirty-one anomalies associated with Cretaceous to Quaternary sedimentary rocks. Two major belts of first-priority anomalies are noteworthy. The first is a northwesterly trending zone in the Rockies that may be structurally controlled, and the second is a northwesterly trending belt west of the Sweet Grass Arch that may be stratigraphically controlled.
