Appendices containing data on uranium resources in the Gillette Quadrangle to accompany a report on U.S. uranium resources in Wyoming, South Dakota, and Montana.

From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

The following report is the first in a series of volumes presenting data recorded during the months of August and September, 1978, from a radiometric and magnetic survey taken in four quadrangles between eastern Wyoming, North and South Dakota, and southern Montana (Newcastle, Gillette and Ekalaka).

Data gathered at stream sediment sites in the Edgemont detail area, including applicable water chemistry measurements (e.g., pH, conductivity, alkalinity) and elemental analyses.

Data gathered at well water sites in the Edgemont detail area, including applicable water chemistry measurements (e.g., pH, conductivity, alkalinity), physical measurements (e.g., temperature, well description, scintillometer readings), and elemental analyses.

The following report presents results of the Edgement detailed geochemical survey. Field and laboratory data are presented for 109 groundwater and 419 stream sediment samples.

Documentation outlining characteristics of field data samples taken in the Edgemont detail area.

Uranium resources of the Newcastle 1°x2° Quadrangle, Wyoming and South Dakota were evaluated to a depth of 1,500 m (5000 ft) using available surface and subsurface geologic information. Many of the uranium occurrences reported in the literature and in reports of the U.S. Atomic Energy Commission were located, sampled and described. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, were outlined. Areas favorable for uranium deposits in the subsurface were evaluated using gamma-ray logs. Based on surface and subsurface data, two areas have been delineated which are underlain by rocks deemed favorable as hosts for uranium deposits. One of these is underlain by rocks that contain fluvial arkosic facies in the Wasatch and Fort Union Formations of Tertiary age; the other is underlain by rocks containing fluvial quartzose sandstone facies of the Inyan Kara Group of Early Cretaceous age. Unfavorable environments characterize all rock units of Tertiary age above the Wasatch Formation, all rock units of Cretaceous age above the Inyan Kara Group, and most rock units of Mesozoic and Paleozoic age below the Inyan Kara Group. Unfavorable environments characterize all rock units of Cretaceous age above the Inyan Kara Group, and all rock units of Mesozoic and …
