Radioactivity in Some Oil Fields of Southeastern Kansas (open access)

Radioactivity in Some Oil Fields of Southeastern Kansas

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 wells in the areas of high radioactivity.

Uranium Series Disequilibrium in Radioactive Ores

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.

Uranium-Bearing Sandstone in the White River Badlands, Pennington County, South Dakota (open access)

Uranium-Bearing Sandstone in the White River Badlands, Pennington 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.

Geology of the Raint Day Uranium Mine Garfield County, Utah (open access)

Geology of the Raint Day Uranium Mine Garfield County, Utah

From abstract: The Rainy Day mine in the Circle Cliffs area, Utah, is developed Dn a long slender pod of uranium ore. Ore is localized in siltstone of the Moenkopi formation of Triassic age, on the south edge of a channel about 3,300 feet wide by 40 feet deep that is filled with sandstone of the Shinarump member of the Chinle formation of Triassic age. Shale of the Chinle rests directly on siltstone of the Moenkopi on either side of the channel.

Results of Reconnaissance for Radioactivity in Parts of the Alma District, Park County, Colorado (open access)

Results of Reconnaissance for Radioactivity in Parts of the Alma District, Park County, Colorado

Abstract: Pitchblende was discovered in July 1951 in the Alma mining district, Park County, Colo0 , by the U0 S. Geological Survey acting on behalf of the U. So Atomic Energy Commission. The pitchblende is associated with Tertiary veins of three different geologic environments: 1) veins in pre-Cambrian rocks, 2) the London vein system the footwall block of the London fault, and 3) veins in a mineralized area east of the Cooper Gulch fault. Pitchblende is probably not associated with silver-lead replacement deposits in dolomite. Secondary uranium minerals, as yet undetermined, are associated with pitchblende on two London vein system mine dumps, and occur in oxidized vein material.Lfrom dumps of mines in the other environments. Although none of the known occurrences are of commercial importance, the Alma district is considered a moderately favorable area in which to prospect for uranium ore, because twenty-four of the forty-three localities examined show anomalous radioactivity; samples from anomalously radioactive localities, which include mine dumps and some underground workings, have uranium contents ranging from 0.001 to l.66 percent.

Engineering Geology Bearing on Harbor Site Selection Along the Northwest Coast of Alaska from Nome to Point Barrow (open access)

Engineering Geology Bearing on Harbor Site Selection Along the Northwest Coast of Alaska from Nome to Point Barrow

From abstract: This report describes geologic and oceanographic factors relevant to the selection of a site in northwestern Alaska, at which an experimental harbor can be created by the explosion of a nuclear device. Part I describes the results of a preliminary survey of the entire coastal and offshore region between Nome and Point Barrow: Part II consists of a more detailed evaluation of the Cape Thompson-Cape Seppings area; and Part III is a theoretical consideration of the effect of the ocean upon the temperature and distribution of permafrost. The report is based entirely upon the study of published and unpublished reports, field notes, and maps, interviews with the few geologists who have visited the region, and the interpretation of aerial photographs.
