From abstract: The distribution of the known uranium deposits of the Colorado Plateau is being analyzed in order 1) to test for systematic relationships between that pattern and geologic factors, 2) to help guide exploration, and 3) to appraise the potential resources of the region and of each of its component areas.

From abstract: A radioactivity survey of the Black Rock district in southern Yavapai County, Ariz, disclosed anomalous radioactivity in several localities, chiefly at the Abe Lincoln mine in sec. 11, T. 8 N., R. 3 W., about 14 road miles northeast of Wickenburg. The Abe Lincoln vein system occupies a fault zone which strikes N. 500 E. and dips from 780 to 870 NW. Moderate radioactivity is present at the Bracken property and at several other localities in the Black Rock district. The writers recommend re-opening the Abe Lincoln mine to permit a more extensive examination of the vein.

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 nine radioactive mine dumps in the Eureka Gulch area of the Central City District of Gilpin County, Colorado, that were discovered between 1951 and 1953.

Report discussing spectrographic analyses of rocks, ores, mill products, and smelter products. From Abstract: "The analyses are grouped by states and by major raw mineral raw materials. The samples vary widely in character and in kind of material. They were analyzed chiefly by spectrographic methods, the accuracy of which increased during the later stages of the work."

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 report about radioactivity reconnaissance during 1949 in the vicinities of Ketchikan, Goddard Hot Springs, Chichagof, Funter Bay, and Juneau which revealed no significant concentrations of radioactive materials.

Report discussing the results of a 1952 reconnaissance for radioactive deposits that was conducted in selected areas of eastern Alaska.

Report discussing two botanical methods of prospecting for uranium ores on the Colorado Plateau. The first method involves analyzing tree branch tips for uranium content, and the second involves the mapping of indicator plants.

Report presenting the results of one part of an investigation of the regional geology of central Florida.

Report discussing the U.S. Geological Survey's investigation of radioactive material found on Mountain View mining property of the Hyder district in southeastern Alaska. No commercially valuable uranium was found in this investigation.

Report discussing a spectrographic determination of contamination in rock samples that had been pulverized with heavy grinding machinery made of alumina ceramic.

The following report presents a preliminary account of the geology and economic aspects of the uranium deposits in the Eureka Gulch area.

The following report studies samples from radioactive deposits in the Hyder district of southeastern Alaska.
