Geologic maps and structure sections of the Johnson Creek Quadrangle in Caribou County, Idaho. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report about the Lemhi Pass area in the Beaverhead Mountains, Lemhi County, Idaho, and Beaverhead County, Montana, which was undertaken to determine the area as a potential source of thorium.

From introduction: This report describes the general geologic setting, the occurrences of uranium or radioactivity in the Fall Creek, Idaho area and adjacent areas, the probable nature of the mineralization and origin of the deposits, and the estimated reserves of uranium-bearing rock.

Report discussing the geology and uraniferous carbonaceous rocks found in the Bear River of the Fall Creek area of Bonneville County, Idaho. The report provides information regarding the geology of the area, uranium occurrences, distribution of uranium and other elements in carbonaceous materials, origin of uranium occurrences, core drilling results, and inferred reserves.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.

Report describing the phosphorite deposits of the western United States with the objective of outlining features that are common to both the Kara Tau phosphorite deposits of Russia and the western United States deposits in an effort to define their origin.

Report discussing an investigation of the Centennial Range of Montana and Idaho, and the phosphate deposits of this area. Information on the geology of the area and deposits are given as well as information regarding the quality and location of phosphate deposits.

A preliminary report on the geology of the phosphate deposits located in the Centennial Range in Montana and Idaho.

From abstract: Uranium-bearing carbonaceous shale and lignite beds are exposed in the Goose Creek district of southern Cassia County, Idaho. The district includes about 150 square miles in Tps. 14 to 16 So, Rs, 20 to 22 E., Boise meridian.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Report discussing a reconnaissance for uranium-bearing carbonaceous rocks during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. From Abstract: "Uranium in small amounts occurs in several of the areas examined, but no deposits were found that might have commercial possibilities."

From abstract: Approximately fifty radioactive deposits and nearly fifty properties not abnormally radioactive were examined during a geologic reconnaissance for radioactive minerals in Idaho, Washington, and western Montana during the period July 1952 -- June 1955. The most important uranium deposits are in or near granitic to quartz monzonitic intrusions of probable Cretaceous age in central and northern Idaho, westernmost Montana, and northeastern Washington.

Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.

Report discussing investigations seeking uranium in deposits of black shale around the geographical areas of the Western States

Abstract: A radiometric reconnaissance, using a portable beta-gamma survey meter, of some geologic formations ranging in age from Cambrian to Cretaceous, and springs in southeastern Idaho, western Wyoming, and northern Utah, has shown that none of them are sufficiently radioactive to warrant further examination of them in the area.

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

Report discussing investigation of the relation of uranium and phosphate in the Phosphoria formation and its close stratigraphic equivalents.

Report discussing a program of core drilling to explore the underground extent and grade of uranium-bearing carbonaceous shale and lignite beds in the Goose Creek district during August and September 1953.

Discussing the results of core drilling for uranium-bearing carbonaceous shale and lignite in the Goose Creek District, in Cassia County, Idaho

Report discussing a study aimed at mapping out stratigraphic sections of the Permian Phosphoria formation in order to locate phosphate beds.

Report containing abstracts of some stratigraphic sections of the Phosphoria formation in southeastern Idaho.

Report discussing the U.S. Geological Survey's investigation of stratigraphy of parts of the Phosphoria formation in Idaho. Abstracts of stratigraphic sections and analytical data are included for several locations in the area.
