Identification and Occurrence of Uranium and Vanadium Minerals From the Colorado Plateaus

Description: 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."

Uranium-Bearing Sandstone in the White River Badlands, Pennington County, South Dakota

Description: From abstract: The uranium mineral uranocircite, a barium uranyl phosphate, occurs in a sandstone channel in the Chadron formation of Oligocene age in the White River Badlands, Pennington County, S. Dak. A vertical section of the basal 1-foot of the channel contains 0. 25 percent uranium. There are also small amounts of metatyuyamunite (?) in the upper part of a freshwater lime stone bed in the Chadron formation and carnotite in chalcedony veins in the overlying Brule formation, also of Oligoce… more

Carnotite-Bearing Sandstone in Cedar Canyon, Slim Buttes, Harding County, South Dakota

Description: From abstract: Carnotite-bearing sandstone and claystone have been found in the Chadron formation of the White River group of Oligocene age in the southern part of the Slim Buttes area, Harding County, S. Dak. The carnotite is an efflorescent yellow coating on lenticular silicified sandstone. Locally, the mineralized sandstone contains 0.23 percent uranium. The uranium and vanadium ions are believed to have been derived from the overlying mildly radioactive tuffaceous rocks of the Arikaree form… more

Geology of the High Climb Pegmatite, Custer County, South Dakota

Description: From abstract: The High Climb pegmatite, Custer County. S. Dak., belongs to the series of pegmatitic and granitic rocks that characterize the Harney Peak region of the southern Black Hills. It intrudes pre-CamInbriani metamorphic rocks consisting chiefly of quartz-mica schist. Along part of the pegmatite contact the country rock has been altered to a tourmaline-rich schist.

Uranium Deposits in Fall River County, South Dakota

Description: From abstract: In 1951 uranium deposits containing carnotite were discovered in the southern Black Hills near Edgemont, Fall River County, S. Dak. Many carnotite deposits have since been found in sandstones in the Inyan Kara group of Early Cretaceous age, and uranium-bearing material has been discovered in the Minnelusa sandstone of Pennsylvanian age and the Deadwood formation of Cambrian age in the southern Black Hills. Ore has been produced only from the Inyan Kara group, mostly within an are… more

Geology of the Calamity Peak area, Custer County, South Dakota

Description: A report discussing and area of 2.5 square miles along the southwest border of the pre-Cambrian granitic rocks complex in the pre-Cambrian core of the Harney Peak region, Black Hills, South Dakota that was mapped to determine the relationship between the granite-pegmatite complex and the pegmatites containing beryl and other industrial minerals. This investigation was part of the U.S. Geological Surveys program for the investigation of domestic beryllium resources and was carried out on behalf … more

Laboratory Study of Uranium-Bearing Lignite from Western North Dakota and South Dakota

Description: From abstract: "Laboratory studies of uraniferous coal were started in connection with explorational core drilling in 1951. The cores were described and used for coal analyses, for determinations of uranium and other mineral elements, and for microscopical investigations. Results of microscopical studies are feature in this report."
