A report regarding the results of core drilling for uranium-bearing lignites in the Bar H Area, Slim Buttes, Harding County, South Dakota. This report is done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission

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 of the Atomic Energy Commission.

This report summarizes the information on the substation in South Dakota like locations,elevations,exposures,instrumentation from the date state was established through 1955.

A report about carnotite-bearing sandstone and clay which has 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. Dakota. The mineralized sandstone contains as much as 0.23 percent uranium.

The following report covers studies and investigations of uranium deposits in the Black Hills of South Dakota and Wyoming. The ore minerals include carnotite, tyuyamunite, metatyuyamunite, corvusite, rauvite, uraninite, and coffinite, as well as minor amounts of other uranium and vanadium minerals.

Report discussing a study on four beds of uranium-bearing lignite from the Slim Buttes area of Harding County, South Dakota.

A report about the uranium content of the Sharon Springs member of the Pierre shale in South Dakota and northeastern Nebraska.

Report discussing uranium deposits containing carnotite in the southern Black Hills near Edgemont, Fall River County, South Dakota.

The following report covers the Petrographic study of Early Cretaceous age sandstone beds in the Fall River formation and the Fuson-Lakota formations, as well as Late Jurassic age beds in the underlying Unkpapa and Morrison formations along the western side of the Black Hills.

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."

Report discussing a geological study performed to find uraniferous lignites in North Dakota, Eastern Montana, north-central Wyoming, and northwestern South Dakota. "Deposits of uraniferous lignites were discovered at Blue Buttes, eastern Montana; and at North Cave Hills, South Cave Hills, and at Slim Buttes in northwestern South Dakota."
