From abstract "As part of the Department of Energy (DoE) National Uranium Resource Evaluation Program, LKB Resources, Inc. has performed a rotary-wing reconnaissance high sensitivity radiometric and magnetic survey, encompassing several 1:250,000 quadrangles in southwestern Arizona and southeastern California. The surveyed area consisted of approximately 9300 line miles. The radiometric data was corrected and normalized to 400 feet terrain clearance. The data was identified as to rock type by correlating the data samples with existing geologic maps. Statistics defining the mean and standard deviation of each rock type are presented as listings in Volume I of this report. The departure of the data from its corresponding mean rock type is computed in terms of standard deviation units and is presented graphically as anomaly maps in Volume II and as computer listings in microfiche form in Volume I."

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Phoenix 10 x 2 quadrangle. Surface sediment samples were collected at 1388 sites, at a target sampling density of one site per 15 square kilometers (6 square miles). Ground water samples were collected at 155 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: 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.

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.
