Report documenting the suitability of North Dakota and South Dakota for plant locations to produce synthetic liquid fuels, based on raw materials, water sources, and local interest...add details/adjust

From introduction: This report describes briefly the deposits of uranium ore discovered in June 1951 near Edgemont, Fall River County, South Dakota. It is a preliminary report, based upon rapid reconnaissance of a small area around the original discovery. It is intended for those who may be interested in further prospecting a large potential area and in developing and mining the deposits.

Report issued by the U.S. Bureau of Mines on the beryl deposits in the northern Black Hills of South Dakota. The properties and quantity of the beryl samples were evaluated. Maps, illustrations, and tables are included in the report.

From introduction: This report presents, in tabular form, the results of radiometric and geologic reconnaissance made in the Craven and Coal Canyon areas during the period November 27 to December 7, 1951, in accordance with plans outlined in Trace Elements Memorandum Report 152, "The carnotite prospects of the Craven Canyon area, Fall River County, South Dakota." Assay data from the claims examined by L. R. Page and J. A. Redden are not included in this report. This work was done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing the descriptive geology of three new formations of metamorphic rocks and details of about 420 pegmatites in the Fourmile area of Custer County, South Dakota.

From introduction: This report details the reconnaissance for uraniferous lignites in North Dakota, South Dakota, Montana, and Wyoming during 1948 and 1949.

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."

Purpose: The main objective of the Dakota core drilling program was to determine reserves of uraniferous lignite based on chemical uranium and spectrographic determinations from unweathered samples, particularly from those areas where surface sampling of the beds during the previous field season indicated that significant deposits of uranium-bearing lignite might be present. A secondary objective was to obtain fresh samples and to measure the radioactivity of the overlying Oligocene White River and Miocene Arikaree formations from which the uranium in lignite is believed to have been derived.

Report discussing studies regarding uraniferous lignite from the Mendenhall strip mine in Harding County. The geochemical and mineralogical properties of lignite was analyzed and discussed.

From abstract: In July 1952 an occurrence of autunite was found in the northern part of the Black Hills, South Dakota, during a reconnaissance for radioactive deposits.

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 the geology of the High Climb Pegmatite located in Custer County, South Dakota. The main focus of this report is the zones of this area that contain "widely varied mineral assemblages."

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.

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

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

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 Oligocene age.

Report discussing the results of core drilling in the Mendenhall Area of Harding County, South Dakota. This drilling was aimed at collecting data regarding uranium-bearing lignite. The report provides information regarding drilling operations, stratigraphy of the area, structure, and lignite deposits.

A report regarding the results of core drilling for uranium-bearing lignite, Mendenhall area, Harding County, South Dakota. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing the geology of the Calamity Peak area of Custer County, South Dakota. This area "was mapped to determine the relationship between the granite-pegmatite complex and the pegmatites containing beryl and other industrial minerals."

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.
