Notes

Abstract: The Kalispell Quadrangle, Montana, was evaluated using criteria developed for the National Uranium Resource Evaluation program for the purpose of identifying and delineating areas containing geologic environments favorable for uranium deposits. Reconnaissance and detailed investigations included the evaluation of reported uranium occurrences, geochemical sampling, and field evaluation of hydrogeochemical and stream-sediment anomalies. Results of the investigations indicated that two areas have potential for uranium deposits in or related to plutonic rocks. Both areas contain peralkaline plutonic rocks and are possibly spatially and genetically related to a larger alkaline-ultramafic complex. The nonradioactive plutonic rocks of the Bobtail stock are possibly related to this larger complex but are considered unfavorable for uranium deposits. Precambrian volcanic and metasedimentary rocks outside areas containing polymetallic vein-type silver-lead-zinc enrichment are also considered unfavorable for uranium deposits. Paleozoic, Mesozoic, and Cenozoic sedimentary rocks and Quaternary deposits are also unfavorable.

National Uranium Resource Evaluation: Kalispell Quadrangle, Montana

From Introduction: "The Kalispell Quadrangle, in northwestern Montana (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Favorable environments, as determined by surface and subsurface investigations, are those that could contain uranium deposits of at least 100 tons U3O8 at an average grade not less than 100 ppm U3O8."
