Leaching study of oil shale in Kentucky: With a section on hydrologic reconnaissance of the oil shale outcrop in Kentucky
Samuel S. Leung, D.W. Leist, R. W. Davis, Steven Cordiviola
1984, Water-Resources Investigations Report 84-4073
Oil shales in Kentucky are rocks of predominantly Devonian age. The most prominant are the Ohio, Chattanooga, and New Albany Shales. A leaching study was done on six fresh oil shale samples and one retorted oil shale sample. Leaching reagents were distilled water, 0.0005 N sulfuric acid, and 0.05 N...
Effects of storm-water runoff on water quality of the Edwards Aquifer near Austin, Texas
Freeman L. Andrews, Terry L. Schertz, Raymond M. Slade Jr., Jack Rawson
1984, Water-Resources Investigations Report 84-4124
Analyses of samples collected from Barton Springs at approximately weekly Intervals and from Barton Creek and five wells in the Austin area during selected storm-runoff periods generally show that recharge during storm runoff resulted in significant temporal and area! variations in the quality of ground water in the recharge zone...
The Alaskan Mineral Resource Assessment Program: Guide to information contained in the folio of geologic and mineral-resource maps of the Medfra quadrangle, Alaska
William Wallace Patton, E. J. Moll, Harley D. King
1984, Circular 928
The Medfra quadrangle in west-central Alaska was investigated by a multidisciplinary team of geoscientists to assess its mineral resources. This Circular is intended to serve as a guide to a folio of 13 separate Open-File Reports covering various aspects of these investigations, including geology, bedrock and stream-sediment geochemistry, potassium-argon dating,...
The Conterminous United States Mineral Appraisal Program; background information to accompany folio of geologic, geochemical, geophysical, and mineral resources maps of the Walker Lake 1 degree x 2 degrees Quadrangle, California and Nevada
John Harris Stewart, M.A. Chaffee, J. C. Dohrenwend, D. A. John, R. W. Kistler, F. J. Kleinhampl, W. D. Menzie, Donald Plouff, L. C. Rowan, Norman J. Silberling
1984, Circular 927
The Walker Lake 1? by 2? quadrangle in eastern California and western Nevada was studied by an interdisciplinary research team to appraise its mineral resources. The appraisal is based on geological, geochemical, and geophysical field and laboratory investigations, the results of which are published as a folio of maps, figures,...
Map showing outcrops of granitic rocks, Basin and Range Province, Nevada
K. A. Sargent, Kurt Roggensack
1984, Water-Resources Investigations Report 83-4119-D
This map report is one of a series of geologic and hydrologic maps covering all or parts of States within the Basin and Range province of the western United States. The map reports contain information on subjects that characterize the geohydrology of the province, including the ground-water hydrology, ground-water quality,...
Maps showing geomorphic and geologic evidence for Late Quaternary displacement along the Surprise Valley and associated faults, Modoc County, California
Charles W. Hedel
1984, Miscellaneous Field Studies Map 1429
The maps in this report are designed to show the location, nature, and age of fault traces and lineaments that are interpreted to be the result of late Quaternary movement along the Surprise Valley and associated faults. These characteristics are important to scientists and engineers who study the surface faulting...
Habitat Suitability Index Models: Walleye
Thomas E. McMahon, James W. Terrell, Patrick C. Nelson
1984, FWS/OBS 82/10.56
The wall eye is native to freshwater ri vers and 1akes of Canada and the United States, with rare occurrences in brackish water (Scott and Crossman 1973). In the United States, its native range occurs primarily in drainages east of the Rocky Mountains and west of the Appalachians; however, it...
