Report describing the results of geochemical and stream sediment reconnaissance sampling in the Kingman Quadrangle, to look for uranium and trace elements, and to take other measurements.

Report describing the results of geochemical and stream sediment reconnaissance sampling in the Las Vegas Quadrangle, to look for uranium and trace elements, and to take other measurements.

From introduction: "The Bakersfield sheet of the Geologic Map of California (California Division of Mines and Geology, 1978) was used as a basis for the interpretation of the geophysical data. The formation descriptions in Appendix C are derived from this map."

From introduction: The Fresno sheet of the Geologic Map of California (California) Division of Mines and Geology, 1978) was used as a basis for the interpretation of the geophysical data. The formation descriptions in Appendix C are derived from this map. Parts of three physiographic provinces are present in the Fresno quadrangle (Albers, 1966)...

From objectives: In the Salton Sea Quadrangle, reported uranium occurrences were evaluated, and geologic environments thought to be favorable were examined. This report includes the field data collected during that work and a summary of the quadrangle geology and uranium favorability. This is the final report to be prepared on this quadrangle under the NURE program.

This is a airborne reconnaissance report of the Williams Quadrangle in Arizona.

From purpose and scope: The purpose of this project was to determine the uranium favorability of Mesozoic intrusive rocks and Tertiary volcanic and sedimentary rocks in the central Mojave Desert. The project was conducted by Bendix Field Engineering Corporation (BFEC) under the auspices of the Grand Junction Office of the U.S. Energy Research and Development Administration (ERDA). The scope of the project included determination of the uranium content of different rock types, determination of the nature and extent of rock characteristics favorable for the formation of uranium deposits, and examination of known uranium deposits.

From operational program: This final report includes a general geologic description of the area, including descriptions of the various geologic units and correlates the airborne data to the geologic units as provided by the geologic maps. Also included is a frequency distribution study of the data as a function of the geologic units encountered over the NTMS area including the tie line data. This report also consists of a discussion of the area surveyed and includes all single record reduced data and averaged record data listings on microfiche.

From abstract: This data report presents results of ground water and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Death Valley 1 x 2 quadrangle.

From introduction: The objective of this survey is to develop a geochemical data base for use by the private sector to locate regions of anomalous uranium content. Prior to wide area coverage, several pilot studies are being undertaken to develop and evaluate sampling and analytical techniques. The first of these studies was conducted in the Walker River Basin.

From abstract: This abbreviated data report presents results of ground water and surface sediment reconnaissance in the National Topographic Map Series (NTMS) Salton Sea 10 x 2 quadrangle. Surface sediment samples were collected at 997 sites. Ground water samples were collected at 76 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.

Introduction: The geologic map of the Mariposa quadrangle, which was used as a basis for the interpretation, was supplied by Bendix Field Engineering Corporation. The Formation descriptions in Appendix C are derived from this map supplemented with information from California Division of Mines and Geology (1967).

This is an airborne reconnaissance report on several quadrangles in Arizona, California, and Nevada.

From introduction: Our particular interest in the uranium potential of the Proterozoic quartz-pebble and quartzite-pebble conglomerates of the Kingston Peak Formation has been based upon: 1. Known uranium occurrences of low to intermediate grade in a peliticarkosic sulfide-bearing unit near the base of the formation; the "Favorable Submember" of this report. 2. Uranium occurrences and widespread anomalies in underlying Proterozoic granitic-metamorphic rocks, including the World Beater Complex, within and bordering the basin in which the conglomerates were deposited. 3. Reported minor shows of uranium associated with extensive anomalous radioactivity in the conglomerates themselves.
