COBRA Program - RC Transformation in Wyoming

Report issued by the Bureau of Mines over studies conducted on vanadium deposits in Lincoln County. As noted in the introduction, "the following report covers the history of the district, outlines the physical features and communications, mentions the property, and notes the ownership. The deposits and ore are described, and work performed by the Bureau of Mines is explained in detail" (p. 1). This report includes tables, and maps.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Gillette quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

Abstract: On July 16, 1953, a diamond core-drilling program was begun in the Pumpkin Buttes area to secure geologic information.

Abstract: A program of airborne radiometric reconnaissance for uranium was conducted in eastern Fremont and western Natrona Counties, in central Wyoming, during the summer and fall of 1954, by the U.S. Atomic Energy Commission.

From introduction: This study is a comprehensive investigation of altered sandstone associated with uranium deposits near Pumpkin Buttes in the Powder River Basin of Wyoming, and the detection of such alteration using remote sensing technology. The purpose of this study is two-fold: 1) to develop video image processing techniques that will preferentially enhance areas of alteration associated with uranium deposits and enable mapping of these areas, and 2) to investigate the spectral, geochemical, and mineralogical characteristics of altered areas which make them detectable on remote sensor data. Once these video processing techniques have been defined, they may be applied as exploration tools to new areas with similar surface and geological environments. In this way, remote sensing can serve as a valuable tool for uranium exploration.

This report discusses upland erosion control, revegetation activities, and long-term maintenance plans for the Ruby Pipeline Project, a pipeline that extends from Wyoming to Oregon.

Report of uranium and thorium findings from a reconnaissance of the Casper NTMS quadrangle through water and sediment samples analyzed for uranium elements by delayed neutron counting and fluorometry, thorium, and 41 additional elements by neutron activation analysis, x-ray fluorescence, and arc-source emission spectroscopy.

From abstract: Uranium deposits and radioactivity anomalies have been found in the eastern half of the area underlain by the Browns Park formation in northwestern Colorado, south-central Wyoming, and northeastern Utah. The deposits are in eolian, lacustrine, and fluvial sandstones, tuffaceous sandstones, and limestones all of which were deposited on two converging pediments during Miocene time. At least one eastern and one western facies of lacustrine and fluvial sedimentary rocks are separated by a belt of eolian sandstones. The faces may be distinguished in the field and by petrographic and heavy-mineral studies in the laboratory.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Data collected as part of the hydrogeochemical and stream sediment reconnaissance for Preston quadrangle, Wyoming including laboratory data on waters and sediments as well as field data.

The following report discusses the results from studies made during a program of geological mapping and exploratory core drilling that was carried out from 1951 to 1953 by the U.S. Geological Survey on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission to determine the areal distribution, thickness, and uranium content of coal in the eastern part of the Red Desert area, Sweetwater County, Wyoming.

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

Report discussing a reconnaissance for uranium-bearing carbonaceous rocks during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. From Abstract: "Uranium in small amounts occurs in several of the areas examined, but no deposits were found that might have commercial possibilities."

Appendices containing data on uranium availability in the Thermopolis Quadrangle to accompany a report on U.S. uranium resources in Wyoming.

Appendices containing data on uranium occurrences in the Rawlins Quadrangle in addition to emission spectroscopy results, electric and gamma-ray logs, lithologic logs and petrology reports to accompany a report on U.S. uranium resources in Wyoming and Colorado.

Report describing the analysis of water and sediment samples taken from the Cheyenne quadrangle in Wyoming to determine if they contained uranium. Several areas were identified for further study, based on initial analyses.

From abstract: This report is intended to supplement the brief interpretation of geochemical data presented in the "Hydrogeochemical and Stream Sediment Detailed Geochemical Survey for the Edgemont South Dakota; Wyoming" report (Butz, et al, 1980).

From Introduction: "The Rawlins Quadrangle (2º) is in south-central Wyoming and extreme northwest Colorado (Fig. 1). Evaluation of the quadrangle was conducted to identify and delineate areas that contain environments exhibiting characteristics common to known uranium-bearing environments."

Abstract: Field and laboratory data are presented for 410 water samples and 702 sediment samples from the Preston Quadrangle, Wyoming; Idaho. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-70(78). The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee.

From introduction: Reported herein are uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Newcastle National Topographic Map Series (NTMS) quadrangle, Wyoming, by the Los Alamos Scientific Laboratory (LASL).

The following report studies uranium ore deposits discovered in the Browns Park Formation, south-central Wyoming and northwest Colorado.

A report regarding uranium-bearing coal in the eastern part of the great divide basin, in sweetwater county, Wyoming. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A generalized geologic map shows the locations of the uranium mines and some of the many occurrences and prospects in the Gas Hills district. Included also are recently-mapped structural features and results of analyses of uranium in water.
