Report discussing a reconnaissance search for uranium in shale during August 1953 in western Nebraska and southern South Dakota. The reconnaissance was part of the U.S. Geological Survey's search for uranium in carbonaceous materials.

Report discussing the investigation of radioactivity in coal beds and associated rocks from the Pottsville, Allegheny, and Conemaugh formations in Beaver, Clearfield, and Jefferson counties, Pennsylvania. The report provides information regarding the procedures used, descriptive geology of the areas, radioactivity data, factors affecting the occurrence of radioactivity, and a summary.

Report discussing a study on the radioactivity of red and green phase Conway granite from Redstone, New Hampshire. Information regarding the collection and measurement methods are included as well as experimental data and calculations.

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.

A report about a peerless pegmatite which has been a large source of scrap mica and beryl. Feldspar, amblygonite, tantalite-columbite, and cassiterite also have been recovered.

Report discussing the geology of an occurrence of minor amounts of uranium-bearing pitchblende discovered in 1949 by the East Branch of the Huron River, which was subsequently diamond drilled and explored at shallow depths.

From scope of report: "The fluorite district in the western part of the Thomas Range, Juab County, Utah, is one f the newest mining districts in western United States; since 1950 it has been the largest producer of fluorite west of the Mississippi River. The present report covers the geology of the entire fluorite producing area, and supplements an earlier report...on the individual mining properties."

A report regarding the geology of the Thomas Range Fluorite District, in Juab County, Utah. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing an investigation of radioactivity occurrences, mostly caused by thorium in thorite and monazite, in various parts of southeastern Alaska. The geology and structural qualities of these radioactive areas are discussed.

A report regarding a reconnaissance for radioactive deposits in southeastern Alaska, 1952. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Abstract: Several radioactive deposits were found as a result of reconnaissance in the Gold Hill mining area, Boulder County, Colo. The ore deposits of the area have been worked chiefly for gold. All ore shipped has come from fissure veins, most of which are gold telluride veins. There are, however, some important sulfide veins which show a vague zonal distribution of pyritic gold ores and silverlead ores. The results of this reconnaissance suggest a possible relationship of the radioactive deposits to this indistinct sulfide zoning; however, the zoning is so obscure that its practical application to prospecting for uranium is of doubtful value at the present time. Pitchblende, torbernite, metatorbernite, and schroeckingerite have been identified in specimens from the area; however, no uranium minerals have yet been identified from most of the radioactive deposits, and the uraniferous material present is probably in disseminated small particles. Although selected samples from several localities assay 0.10 percent uranium or more, the known deposits are small and probably are not of immediate economic importance
