National Uranium Resource Evaluation: Kalispell Quadrangle, Montana

Description: 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."

National Uranium Resource Evaluation: White Sulphur Spring Quadrangle, Montana

Description: From Purpose: "The White Sulphur Springs Quadrangle, in west-central Montana between latitude 46º and 47ºN. and longitude 110º and 112ºW. (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 not less than 100 ppm U3O8."

Reconnaissance for Trace Elements in North Dakota and Eastern Montana

Description: From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken … more
