The final report regarding the National Logging Program for the National Uranium Resource Evaluation.

This report summarizes and interprets the data dro about 500 stream sediment samples, 500 stream water samples, and 500 ground water samples, each analyzed for 40 to 50 elements.

The following report describes the study of sediment in South Park, Colorado, the study taking 464 water samples to test for uranium in the Rocky Mountains.

This report explains the development of data enhancement and display techniques for geochemical data in the Hydrochemical and Stream Sediment Reconnaissance (HSSR) surveys taken in the Winston-Salem quadrangle in North Carolina, Virginia, and Tennessee.

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) San Bernardino 10 x 2 quadrangle. Surface sediment samples were collected at 1539 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Surface water samples were collected at 39 of these sites. Ground water samples were collected at 392 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.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Okanogan and Sandpoint quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

The following report gives detailed results of the geochemical survey taken in Buffalo-Lignite, South Dakota. Field and laboratory data are presented for 163 groundwater and 660 stream sediment samples collected within the Custer and Slim Buttes project areas.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

Report documenting the results of chemical analysis for 1583 water and 503 sediment samples in the Dalhart quadrangle of northeastern New Mexico, northwestern Texas, and western Oklahoma. It includes an overview of the area, methods, data analysis, and evaluation.

From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer-controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.
