Review of the use of magnetic concentrates in geochemical exploration
W.C. Overstreet, G.W. Day
1985, Open-File Report 85-541
Magnetic concentrates recovered readily by hand magnet from alluvial sediments or panned concentrates have been used successfully in exploration as a geochemical sample medium for Cu, Zn, Co, Cr, Mo, Ni, V, Sn, and Be, particularly in arid environments where alluvial sediments may be contaminated by aeolian debris. Opportunity for...
Acoustic-televiewer and acoustic-waveform logs used to characterize deeply buried basalt flows, Hanford site, Benton County, Washington
Frederick L. Paillet
1985, Open-File Report 85-419
Acoustic-waveform and acoustic-televiewer logs were obtained for a 400-meter interval of deeply buried basalt flows in three boreholes, and over shorter intervals in two additional boreholes located on the U.S. Department of Energy 's Hanford site in Benton County, Washington. Borehole-wall breakouts were observed in the unaltered interiors of a...
Use and availability of continuous streamflow records in New Mexico
R.L. Gold, L.P. Denis
1985, Open-File Report 85-572
The use and availability of data collected at streamflow gaging stations in New Mexico is documented as the first phase of a three phase study of the cost-effectiveness of the stream gaging program. Presently, 143 continuous gaging stations are operated. Data collected at most gaging stations have multiple uses. Many...
Selected climatological and hydrologic data, Raton basin, Huerfano and Las Animas Counties, Colorado, and Colfax County, New Mexico
Arthur L. Geldon, P.O. Abbott
1985, Open-File Report 84-138
The hydrology of the coal-bearing Raton Basin of Colorado and New Mexico was investigated by the U.S. Geological Survey. Data in the report were collected from 1977 to 1982, mainly in the watersheds of the Apishapa and Purgatoire Rivers; data from the Cucharas, Canadian, and Vermejo River watersheds are also...
Water-quality data for streams in the Upper North Fork of the Gunnison River, Colorado
J. M. Norris, W.S. Maura
1985, Open-File Report 85-190
The upper reaches of the North Fork of the Gunnison River have been an area of active coal mining for many years. Recently, concerns about impacts of coal mining on surface-water quality have been raised. To answer these concerns, information on existing, or background, water quality must be known. To...
Sedimentation and water quality in the West Branch Shade River basin, Ohio, 1984 water year
C.J. Childress, R.L. Jones
1985, Open-File Report 85-552
Sedimentation in, and flooding of, the West Branch Shade River and its tributaries have been major concerns of residents and State and local officials. The area was extensively surface mined for coal between the mid-1940 's and the early 1960's. Reclamation efforts immediately after mining were unsuccessful. The results have...
