From Introduction: "The purpose of this investigation was to examine the question of the availability of geothermal energy and in particular the availability of geothermal energy from the Black Hills of South Dakota.

Report issued by the U.S. Bureau of Mines on the study of secondary-recovery methods of oil production in California. The report discusses methods and properties of this type of oil production, focusing on air injection. This report is in two parts, and contains tables and maps.

Technical paper issued by the Bureau of Mines over the underground wastes of oil and gas in drilling fields. As stated in the introduction, "the writers have endeavored to establish the manner and importance of underground waste by citing a few cases and to show the means whereby it can be prevented" (p. 5). This paper includes illustrations.

Technical report issued by the Bureau of Mines over the different uses of gypsum. The sources and uses of gypsum are presented and discussed. This report includes tables, photographs, and illustrations.

From abstract: Airborne radioactivity surveys in the Mojave Desert region, Kern, Riverside, and San Bernardino counties were made in five areas recommended as favorable for the occurrence of radioactive raw materials: (1) Rock Corral area, San Bernardino County. (2) Searles Station area, Kern County. (3) Soledad area, Kern County, (4) White Tank area, Riverside and San Bernardino counties. (5) Harvard Hills area, San Bernardino County. Anomalous radiation was detected in all but the Harvard Hills area.

Purpose and scope: The U.S. Marine Corps conducts training maneuvers in the study area. Lack of a local source of water has severely limited the utilization of the area. In the past, limited quantities of water have been transported to the area by truck or helicopter. The purpose of this study was to determine the feasibility of obtaining a supply of ground water in the area for use when field maneuvers are being conducted. The major effort for this study was concentrated on the part within the Marine Corps base boundary. The study involved the assessment of ground-water quality, ground water in storage, and aquifer characteristics.

This report presents the results of a "multiple-reach method-of-characteristics flow-simulation model" applied to a ten point eight mile portion of the Sacramento River in 1976. It includes a map, graphs, and a table.

From introduction: The purpose of this investigation is to provide the additional geohydologic information needed for Monterey County to develop plans for the optimum utilization of its water resources--particularly in the Prunedale and Aroms areas.

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.

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 abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Santa Cruz 1 x 2 quadrangle. Surface sediment samples were collected at 1270 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Ground water samples were collected at 636 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.

From Introduction: "The Reno Quadrangle, Nevada and California (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Favorable environments are those that could contain at least 100 tons U3O8 at an average grade of at least 0.01% U3O8."
