Reports on Investigations of Uranium Anomalies

Description: Introduction: The Hylas Zone, a northeast-trending belt of mylonite and ultramylonite, lies in the eastern Piedmont Province of Virginia and borders the northern end of the Richmond Basin (Fig. I-1). The north-trending Richmond Basin is 58 km long and a maximum of 16 km wide. Early indications of anomalous uranium concentrations in the region came from discussions with Jan Krason, GeoExplorers International, Denver, who had worked in the area. Examination of aerial radiometric data (Geodata International, 1975) and HSSR data (Cook, 1981) indicated anomalous values of uranium in the area northwest of Richmond. During June 1981, a 5-day trip to the Hylas area was undertaken to collect rock and ground-water samples and to identify possible source and host rocks of uranium.

Geologic Study of Kettle Dome, Northeast Washington: Final Report

Description: From abstract: This geologic study of Kettle dome, northeast Washington, encompasses an area of approximately 800 square miles (2048 sq km). The evaluation of uranium occurrences associated with the igneous and metamorphic rocks of the dome and the determination of the relationship between uranium mineralization and stratigraphic, structural, and metamorphic features of the dome are the principal objectives. Evaluation of the validity of a gneiss dome model is a specific objective. The principal sources of data are detailed geologic mapping, surface radiometric surveys, and chemical analyses of rock samples.

Favorability for Uranium in Tertiary Sedimentary Rocks, Southwestern Montana

Description: The objective of the study was to evaluate the favorability for potential uranium resources in Tertiary and related strata. Past studies indicate that the Tertiary basins in southwestern Montana are worthy of further investigation because (1) several basins contain a thick sequence of continental sedimentary rocks, (2) several basins are near possible granitic source rocks that have known uranium occurrences, and (3) some of the Montana basins are geologically similar to basins in Wyoming that are host to important sandstone-type deposits. This study focuses on sedimentary rocks of Tertiary age, but includes some rocks of Late Cretaceous and Pleistocene ages. In some areas only a portion of the total Tertiary sedimentary section could be studied because of poor surface exposures and limited subsurface information.

Uranium Favorability of Southwestern Oklahoma and North-Central Texas

Description: The objective of this project was to identify and delineated units and (or) facies that are favorable for uranium in the Upper Pennsylvanian and Lower Permian strata of north-central Texas and southwestern Oklahoma. Mapping of depositional systems in the subsurface was the main emphasis of the study.

Aerial Radiometric and Magnetic Survey of the Lawton National Topographic Map, NI 14-5, Texas and Oklahoma: Volume 1

Description: From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

Uranium in Granites From the Southwestern United States: Actinide Parent-Daughter Systems, Sites and Mobilization: First Year Report

Description: From summary: In this first annual report for subcontract BFEC 79-384-E (Uranium in Granites of Southwestern North America) we have established the general geological and geochemical background for our investigations. We describe the regional setting and some important geochemical patterns, constituting a major uranium anomaly, of the Precambrian basement in the Colorado Plateau region. Three of our investigated samples were derived from a portion of this region in central and northern Arizona. We describe the tectonic and petrologic setting for a fourth sample, a granite from the young (Cretaceous) Peninsular Ranges Batholith of southern California.

Preliminary Study of the Uranium Potential of the Dan River Triassic Basin System, North Carolina and Virginia

Description: From summary: A preliminary geologic investigation was conducted to determine the uranium potential of the Triassic strata in the Dan River basin system (Dan River, Danville, and Davie County Triassic basins) of North Carolina and Virginia. The pre-Triassic Inner Piedmont basement rocks adjacent to the basins were investigated as potential sources of uranium. Outcrops of Triassic and basement rocks were examined and measured for surface radioactivity by scintillometer. Representative rock and saprolite samples were collected for laboratory analyses.

Uranium Favorability of the San Rafael Swell Area, East-Central Utah

Description: Purpose and scope: The purpose of this study was to delineate new areas favorable for uranium exploration in the San Rafael Swell region of east-central Utah. Emphasis was placed on the sandstone and siltstone members of the lower Chinle Formation (Triassic) and on the Salt Wash and Brushy Basin Members of the Morrison Formation (Jurassic). The White Rim Sandstone (Permian) was also studied, but not extensively. This project began in January 1976 and was completed in March 1977. Field work was conducted during the five-month period from February through June 1976.
