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.

Aerial image shows the result of an airborne radioactive survey over an area of 700 square miles in Sweetwater County, Wyoming with the approximate location of three radioactivity anomalies found. Text describes methods used and discusses the anomalies.

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.

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.

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.

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).

"Field and laboratory data are presented for 123 water samples and 749 sediment samples from the Ogden Quadrangle, Utah, and Wyoming. 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."

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.

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.

"Field and laboratory data are presented for 454 water samples 1.279 sediment samples from the Rawlins Quadrangle, Wyoming. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-81(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."

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.

Discussing the study of uranium deposits in the Wind River District in Wyoming, undertaken to determine the relationships between the mineralogy and uranium equilibrium state and the field geology of the deposits.

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."

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.

From Introduction: "The Thermopolis Quadrangle (1º x 2º), Wyoming, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments and formations were evaluated to a depth of 1500 m from surface and subsurface investigations. Areas and environments were categorized as favorable, unfavorable, or unevaluated for uranium deposits."

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

Documentation outlining characteristics of field data samples taken in the Ogden quadrangle.

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

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

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