This report presents data maps and tables as a result of geophysical and radioactive mineral studies made in the Jordan quadrangle, Montana.

This report presents data maps and tables as a result of geophysical and radioactive mineral studies made in the Glendive quadrangle, Montana.

From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

From Introduction: "The Butte Quadrangle, Montana (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Each environment was categorized as favorable, unfavorable, or evaluated according to criteria established in Mickle and Mathews (eds., 1978)."

From Introduction: "The Elk City Quadrangle (1º by 2º), Idaho and Montana, was evaluated to identify and delineate geologic environments that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Sheridan NTMS 1º by 2º Quadrangle (Fig. 1) in north-central Wyoming was evaluated to identify geologic environments that have characteristics favorable for uranium deposition. Only environments to a depth of 1500 m have been evaluated for this project."

From Introduction: "The Sandpoint Quadrangle (Fig. 1) was evaluated to define areas with geologic environments favorable for uranium deposits. Environments were evaluated on the basis of surface investigations because few subsurface data were available."

From Purpose and Scope: "The Billings Quadrangle (2º), Montana and Wyoming, was evaluated to identify geologic units and to delineate areas that exhibit characteristics favorable for uranium deposits that could contain at least 100 tons U3O8 in rocks with an average grade of not less than 100 ppm U3O8. Surface and subsurface data were used to evaluate all geologic environments to a depth of 1500 m (5,000 ft)."

From Introduction: "The Bozeman Quadrangle is south-central Montana was evaluated for geologic environments capable of containing uranium deposits to a depth of 1500 m (5,000 ft.). Most rock types and geographic areas were investigated by surface traverse, and hydrgeochemical data were collected from available well sites."

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."

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."

Text summarizing the features of the 10 type localities and 30 anomalous areas for mineral occurrences in the project area, the Dillon, Butte, Hamilton, and Elk City 1º x 2º NTMS Quadrangles. Each report includes date, chemical symbols for major/minor metals, location data, geochemical features, radiometric features, geophysical features, structural features, and host rocks.

"This project was conducted to integrate National Uranium Resource Evaluation (NURE) geochemical and geophysical data from butte, Dillon, Elk City, and Hamilton NTMS Quadrangles."

Reports summarizing the features of the 24 mineralized localities in the project area, the Wallace and Choteau NTMS Quadrangles, Montana and Idaho. Each report includes date, chemical symbols for major/minor metals, location data, geochemical features, radiometric features, geophysical features, structural features, and host rocks.

This report follows the study to recognize, characterize, and delineate mineralized environments in the Wallace and Choteau quadrangles of Idaho and Montana.

From Purpose and Scope: "The Dubois Quadrangle, Idaho and Montana (Fig. 1), was studied to identify geologic environments and delineate areas favorable for uranium deposits. These reports summarized field observations and contained preliminary evaluations of geologic environments for uranium deposition. The identification of environments favorable for uranium deposition involved collection and interpretation of radiometric, geochemical, and geologic data."

From abstract: All geologic conditions in the Dillon Quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins.
