A.M. Sturrock, B.A. Hanson, J.L. Scarborough, T. C. Winter
1987, Open-File Report 87-216
Research on the hydrology of the Cottonwood Lake area, Stutsman County, North Dakota, includes study of evaporation. Climatic data needed for energy-budget and mass-transfer evaporation studies that were collected during 1983 include water-surface temperature, sediment temperature, dry-bulb and wet-bulb air temperature, vapor pressure at and above the water surface, wind...
Analytical results and sample locality map of stream-sediment, heavy mineral-concentrate, rock, and water samples from the Skedaddle (CA-020- 612) and Dry Valley Rim (CA-020-615) Wilderness Study Areas, Lassen County, California, and Washoe County, Nevada
B. M. Adrian, J. G. Frisken, L. A. Bradley, Cliff D. Taylor, J. B. McHugh
1987, Open-File Report 87-494
In the summer of 1985, the U.S. Geological Survey conducted a reconnaissance geochemical survey of the Skedaddle (CA-020-612) and Dry Valley Rim (CA-020-615) Wilderness Study Areas in Lassen County, California, and Washoe County, Nevada.Skedaddle and Dry Valley Rim are contiguous wilderness study areas (WSA) located in the eastern part of...
Hydrogeologic data from a study of the freshwater zone/salinewater zone interface in the Edwards Aquifer, San Antonio region, Texas
Dianne Pavlicek, Ted A. Small, Paul L. Rettman
1987, Open-File Report 87-389
The highly productive freshwater zone of the Edwards aquifer in the San Antonio region (fig. 1) is the sole-source water supply for more than 1 million people. A transitional interface exists between the freshwater zone and the downdip, salinewater zone. A 1,000 mg/L (milligrams per liter) dissolved solids-concentration contour defines...
White mica geochemistry of the Catheart Mountain porphyry copper deposit, Maine
Robert A. Ayuso
1987, Bulletin 1803
White micas from hydrothermally altered and mineralized zones in the Catheart Mountain Cu-Mo porphyry deposit have regular compositional variations that are generally related to the contents of copper, total iron, and sulfur in the whole rock. Micas in unmineralized rocks exhibit no such relationship. White mica compositions reflect primarily the...
