Assay for uranium and determination of disequilibrium by means of in situ high resolution gamma-ray spectrometry
Allan B. Tanner, Robert M. Moxham, F. E. Senftle
1977, Open-File Report 77-571
Two sealed sondes, using germanium gamma-ray detectors cooled by melting propane, have been field tested to depths of 79 m in water-filled boreholes at the Pawnee Uranium Mine in Bee Co., Texas. When, used as total-count devices, the sondes are comparable in logging speed and counting rate with conventional scintillation...
Simulated changes in ground-water levels resulting from proposed phosphate mining, west-central Florida; preliminary results
William Edward Wilson
1977, Open-File Report 77-882
A digital model of two-dimensional ground-water flow was used to simulate projected changes in the Floridan aquifer potentiometric surface in 1985 and 2000, resulting from proposed ground-water developments by the phosphate mining industry in west-central Florida. The .model was calibrated under steady-state conditions to simulate the September 1975 potentiometric surface....
Chemical data and variation diagrams of igneous rocks from the Timber Mountain-Oasis Valley Caldera Complex, southern Nevada
W. D. Quinlivan, F. M. Byers
1977, Open-File Report 77-724
Silica variation diagrams presented here are based on 162 chemical analyses of tuffs, lavas, and intrusives, representative of volcanic centers of the Timber Mountain-Oasis Valley caldera complex and cogenetic rocks of the Silent Canyon ca1dera. Most of the volcanic units sampled are shown on the U.S. Geological Survey geologic map...
Streamflow characteristics of the Joplin area, Missouri
John Skelton
1977, Open-File Report 77-605
Low-flow and peak-flow frequency data and flow-duration-data, based on records from 21 gaging stations in the Joplin area of southwestern Missouri, are presented. Generalized equations and graphs based on gaging-station records are-shown so that estimates of frequency data and the effects of urbanization on peak flows can be made at...
Ground-water resources of the North Beach Peninsula, Pacific County, Washington
James V. Tracy
1977, Open-File Report 77-647
The anticipated water demand of 425 million gallons per year for the North Beach Peninsula, Pacific County, Wash., can be met by properly developing the ground-water supplies of the area's water-table aquifer. Of the approximately 77 inches of precipitation on the peninsula, an estimated 23 inches is lost to evapotranspiration,...
Effect of channel material on width-discharge relations for perennial streams, with emphasis on streams in Kansas -- a progress report
W. R. Osterkamp
1977, Open-File Report 77-38
Using consistent procedures for width measurement at established streamflow-gaging stations, data were compiled to develop a power-function relation between width and mean discharge for high-gradient perennial streams. High-gradient channels, which generally exhibit low variability for most factors influencing the width-discharge relation, were selected to define a standard exponent in the...
Quantity and quality of drainage from the Argo Tunnel and other sources related to metal mining in Gilpin, Clear Creek and Park Counties, Colorado
Dennis A. Wentz
1977, Open-File Report 77-734
Eighteen metal-mine drainage sources have been located in that part of Gilpin, Clear Creek, and Park Counties, Colo., lying within the Missouri River basin. At least 13 of these sources are known to contain high acidity and (or) trace-element concentrations or to contribute water to adversely affected streams. From January...
National coal resource investigations of the United States Geological Survey
1977, Open-File Report 77-763
The objective of this report is to provide a record of some of the goals and accomplishments of the coal resource investigations of the U. S. Geological Survey for 1977. Successful completion of these goals will aid the Nation in the years ahead because proper usage of coal resource data...
Seismicity of the Pahute Mesa area, Nevada Test Site: 8 October 1975 to 30 June 1976
A. M. Rogers, Geraldine M. Wuollet, P. A. Covington
1977, Open-File Report 77-826
A total of 1,075 earthquakes occurred in the Pahute Mesa area with 2.5≤ML≤4.9 during the period October 28, 1975, to June 28, 1976. The majority of these earthquakes are aftershocks of the nuclear events, Kasseri, Inlet, Muenster, Fontina, Cheshire, Estuary, Colby, and Pool (5.8≤ML≤6.3). Smaller nuclear events (ML≤5.5) on Rainier...
