From abstract: Uranium minerals and radioactivity anomalies occur in many silver lead veins and chalcedony veins and vein zones in the Boulder batholith of southwestern Montana.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Boise, Hailey, Idaho Falls, and Elk City quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

Results of reconnaissance surveys of the Lewistown quadrangle to determine the likelihood of uranium deposits of the area, and additional information about the location and classification of any deposits.

From introduction: This preliminary report details the geology and mineral deposits of the northern Elkhorn Mountains, Montana.

From introduction: The purpose of the study is to evaluate the economic possibilities of radioactive lignites and to determine the geologic factors controlling the accumulation of uranium in lignite.

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 purpose and scope: The purpose of this report is (1) to describe the flow system within the Kootenai Formation, which is the principal aquifer, and (2) to describe the interaction between the Kootenai and overlying and underlying Mesozoic aquifers.

This report provides and analysis of the Paid Leave Analysis grants awarded in 2014 to Massachusetts, Montana, Rhode Island and the District of Columbia. Additionally it identifies general lessons learned about what t takes to study, develop, and implement a state-level paid family and medical leave program.

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.
