Preliminary report discussing uranium that was found in the basal limestone of the Sundance formation of late Jurassic age on the east flank of the Bighorn Mountains in Johnson County, Wyoming. The report provides information regarding geographic setting, geologic setting, stratigraphy, uranium occurrence localities, and origin of uranium in the Mayoworth area.

A preliminary report, discussing uranium in the Mayoworth Area in Johnson County, Wyoming

Report discussing the uranium deposits located in the Miller Hill area of Carbon County, Wyoming. A stratigraphic description of the area is also given.

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 investigation of the extraction of uranium from subbituminous coal collected from the Red Desert, Wyoming. Information on the samples of coal used, experimental data, and summary and conclusions of findings are included.

Report discussing the investigation of 750 square miles of land in Wyoming aimed at locating uranium deposits. Information regarding the area, uranium deposits, mineralogy, and results of the exploration are included.

From abstract: Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities with abnormally high radioactivity were found; uranium minerals are visible at 121 of these localities.

The following report follows a mineral survey of the Glacier Primitive Area and adjoining area in Wyoming, that was made in 1968 and 1969.

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

From introduction: This report details the investigations of the physical stratigraphy of the Phosphoria Formation in northwestern Wyoming.

From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder River Basin in the general vicinity of the Pumpkin Buttes.

Report discussing the investigation of uranium minerals, which were discovered in the Poison Basin area, Carbon County, Wyoming, on October 15, 1953. Information regarding the geographic setting, geologic setting, stratigraphy of the area, uranium occurrences of the area, origin of the uranium, and significance of the area are included.

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 introduction: Geologic mapping was done in the Pumpkin Buttes area, Johnson and Campbell Counties, Wyoming, during the summer of 1952 on behalf of the Atomic Energy Commission. The objectives of the work were: to find uranium deposits, to study their distribution, habit, and occurrence, and to use such knowledge as guides in outlining areas favorable for mineralization.

Abstract: A reconnaissance was made of a large part of the Powder River Basin, Wyoming, during the summer of 1952 to search for uranium deposits in parts of the basin other than the Pumpkin Buttes area. No uranium deposits of economic interest were found, but some rocks of the Tertiary Fort Union formation and the Cretaceous Inyan Kara group were found to be sufficiently uraniferous to justify further search in rocks of these units. Analyses of samples of sandstones, baked shales, and siltstones taken during the reconnaissance show these rocks are considerably more vanadiferous than the average sandstone, or clay and shale.

A report regarding a preliminary reconnaissance survey for thorium, uranium, and rare-earth oxides in the bear lodge mountains, in Crook County, Wyoming. "The purpose of this reconnaissance was to obtain information on the mode of occurrence, extent, and reserves of these deposits. This work was done on behalf of the Division of Raw Materials of the Atomic Energy Commission."

A report regarding uranium-bearing coal in the Red Desert, Great Divide Basin, Sweetwater County, Wyoming. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Abstract: "This report, designed to make available to field geologists and others information on identification and occurrence of uranium minerals of the Colorado Plateaus, contains physical properties, X-ray data, and in some instances results of chemical and spectrographic analysis of 24 uranium and 17 vanadium minerals. Also included is a table giving the optical properties of uranium minerals and a list of locations of mines from which the minerals have been identified."

From abstract: This report describes Cambrian through Mississippian rocks in the Powder River Basin representing five depositional sequences that reflect both the biological evolution and the tectonic development of western North America.

Report presenting the results of core drilling in Sweetwater county, Wyoming aimed at finding uraniferous coal. Information regarding the locations that were drilled, progress made in drilling, geology of the area, reserves of uraniferous coal, and future plans are included.

A report discussing the results of exploratory core drilling for uranium-bearing coal in the Northern Part of the Red Desert Area, in Sweetwater County, Wyoming.

More than nine-tenths of the Upper Cretaceous rocks in northeastern Wyoming are fine-grained shales, mudstones, and calcareous marls. A comparative study of the mineralogy, chemical and mechanical composition, density and porosity, fissility, and lamination of samples of these rocks discloses several relations that throw light on the geologic history and structural deformation of the region, and perhaps on its oil and gas possibilities.

A report about new geochemical, biogeochemical, and sedimentological data gathered from the depositional basins of the Green River Formation.
