National uranium resource evaluation: Billings Quadrangle, Montana
Five environments in the Billings Quadrangle are favorable for the occurrence of uranium deposits that could contain at least 100 tons U/sub 3/O/sub 8/ in rocks that have an average grade of not less than 100 ppM U/sub 3/O/sup 8/. The Mississippian Madison Limestone of the Pryor Mountains, a favorable environment for limestone-type deposits, contains a small mining district that has produced over 110,000 pounds of U/sub 3/O/sub 8/. The Cambrian Flathead Sandstone along the eastern flanks of the Beartooth Mountains is favorable for unconformity-related deposits; the area contains several uranium occurrences. The Pennsylvanian Tensleep Sandstone along the southern flanks of the Pryor Mountains is a favorable environment for Texas roll-type deposits because of lithology, structure, depositional environment, and proximity to a potential source area. The Cretaceous Lakota and Virgelle Sandstones exhibit the lithology, permeability, and volume to host sandstone-type uranium deposits. All other environments in the quadrangle are unfavorable or unevaluated.
