Report describing a high-sensitivity aerial gamma-ray spectrometer and magnetometer survey conducted in the lower Yukon River and Kuskokwim River areas of southwestern Alaska (covering fifteen quadrangles) and in the middle Yukon River valley in Interior Alaska (covering eight quadrangles) as part of the National Uranium Resource Evaluation (NURE) Program of the United States Energy Research and Development Administration (ERDA). This program provides information on reconnaissance radioelement distribution to assist in assessing the uraniferous material potential in the United States. The analysis includes medium values of eU, eTh, and K (equivalent uranium, thorium, and potassium) contents of geological units.

Appendix computer data listings to accompany a report on aerial radiometric and magnetic survey of the Bethel and Yukon areas in Alaska.

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.

Five structure maps showing favorable areas for vein uranium deposits Badger Flats - Elkhorn Thrust project area created for a geologic and geochemical study of the Precambrian igneous and metamorohic rock zones in the project area.

Two maps showing the geologic features of the Western Snake River Basin, Idaho and locations of sample sites, wells, and cross-section locations. Four additional plates illustrate lithologic logs for the 17 petroleum test wells and 2 deep water wells selected for use in the study. The water wells were selected on the basis of total depth, quality of lithologic log, and location with respect to the lines of section. The sections A-A', B-B', C-C', and D-D' are shown on Plates 3 through 6, respectively. (p. 11 of report)

This report presents results of studies made on cenozoic sedimentary rocks in the western Snake River basin of Idaho to determine their favorability for uranium resources.

This report follows the geologic and geochemical study of the Precambrian igneous and metamorohic rock zones in Badger Flats - Elkhorn Thrust area of Park and Teller counties, Colorado.

This report follows the cooperative drilling project between the U.S. Energy Research and Development Administration (ERDA) and the U.S. Geological Survey (USGS) for the coring of granite in the Pedro Mountains of Carbon County, Wyoming.

Plates accompanying report on the Pedro Mountain Drilling Project: a chart illustrating the core lithology of Pedro Mountain No. 1 drill hole; an illustration of the directional survey created by the Seismographic Service Corporation's Birdwell Division; a compiled graph of the caliper, gross gamma, neutron-neutron, and magnetic susceptibility logs created by Bendix Field Engineering Corporation (BEFC) Advanced Technology Division; and an illustration of the BFEC spectral gamma (KUT) log, showing potassium (in PCT) and uranium and thorium (in PPM).

Geophysical logs, created by the Seismographic Service Corporation's Birdwell Division, accompanying report on the Pedro Mountain Drilling Project showing gammy-ray neutron, density, temperature, three-dimensional velocity, electric, and caliper (see pages 10-11 of report). Each represents data collected from the core hole drilled in granite in Carbon County, Wyoming in May 1976.

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.
