The Permian Phosphate Deposits of Western United States

Description: From abstract: The Permian marine phosphorite deposits of the western United States were laid down in the Phosphoria formation and its partial stratigraphic equivalents over an area of about 135,000 square miles in Montana, Idaho, Wyoming, Utah, and Nevada. The deposits in the eastern part of the field lie on the western margin of the structurally simple North American craton.

Domestic Phosphate Deposits

Description: From abstract: Incomplete but recently partly revised estimates indicate the presence of about 10 billion tons of phosphate deposits in the Urited States that is minable under present economic conditions. Deposits too lean in quality or thickness to compete with those in the western and southeastern fields probably contain tens of billions of tons.

Uranium-Bearing Copper Deposits in the Coyote District, Mora County, New Mexico

Description: Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Pennsylvanian and Permian age south of Coyote, Mora County, N. Mex. Mapping and sampling of these deposits indicate that they occur in lenticular carbonaceous zones in shales and arkosic sandstones. Samples from these zones contain as much as 0.067 percent uranium and average 3 percent copper. Metatyuyamunite is disseminated in some of the arkosic sandstone beds, and uraninite was identi… more

Radioactivity in Some Oil Fields of Southeastern Kansas

Description: From abstract: Radium-bearing precipitates derived from 'oil-well fluids have been found in more than 60 oil and gas fields in Cowley, Butler, Marion, Sedgwick, and Greenwood Counties of southeastern Kansas. The abnormal radioactivity of these precipitates has been studied through the use of gamma-ray and sample logs; by radiometric, chemical petrographic, and spectrographic analyses of the precipitates and drill samples; and through the use of chemical analyses of brines collected from oil wel… more

Uranium Deposits in the Red Desert of the Great Divide Basin, Sweetwater County, Wyoming

Description: From introduction: The investigations that are the subject of this report were to appraise the uranium resources of the Red Desert area, and to accumulate data concerning the geology of uranium. Knowledge of the genesis of the schroeckingerite is necessary for a clear appraisal of the deposit.

An Occurrence of Rhenium, Associated with Uraninite in Coconino County, Arizona

Description: From introduction: Twenty-nine samples of sedimentary rocks of Triassic age from the Sun Valley uranium mine in northern Arizona were analyzed spectrographically, and 11 of these samples contained 0.005 to 0.1 percent of the rare metallic element, rhenium.

Reconnaissance for Radioactive Minerals in Washington, Idaho, and Western Montana, 1952-1955

Description: From abstract: Approximately fifty radioactive deposits and nearly fifty properties not abnormally radioactive were examined during a geologic reconnaissance for radioactive minerals in Idaho, Washington, and western Montana during the period July 1952 -- June 1955. The most important uranium deposits are in or near granitic to quartz monzonitic intrusions of probable Cretaceous age in central and northern Idaho, westernmost Montana, and northeastern Washington.

Uranium Deposits of the Carlile Quadrangle, Crook County, Wyoming

Description: From abstract: The uranium deposits in the Carlile quadrangle, southwestern Crook County, Wyo., are in relatively flat-lying sandstone beds in the lower part of the Inyan Kara group of Early Cretaceous age. The Carlile mine has the largest deposit in the quadrangle; the ore minerals are carnotite and tyuyamunite associated with carbonaceous material in a sandstone lens.

Uranium Series Disequilibrium in Radioactive Ores

Description: From introduction: The purposes of this paper are to tabulate and discuss the results of a number of complete disequilibrium analyses, to illustrate a proposed classification of disequilibrium patterns, to study these disequilibria as clues to the understanding of the geochemical history of the samples and of the deposits, and to point out some of the difficulties when simply comparing radioactivity and chemical uranium assays for interpreting equilibrium or disequilibrium in samples.

Summary of Investigations of Uranium Deposits in the Pumpkin Buttes Area, Johnson and Campbell Counties, Wyoming

Description: From abstract: Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities with abnormally high radioactivity were found; uranium minerals are visible at 121 of these localities.
