Hydrologic data for Leviathan Mine and vicinity, Alpine County, California, 1981-83
D.P. Hammermeister, S.J. Walmsley
1985, Open-File Report 85-160
The U.S. Geological Survey collected basic hydrologic and water-quality data during 1981-83 to facilitate the geohydrologic evaluation of the Leviathan Mine area and the design of a pollution-abatement project. Surface-water field data included one or more measurements of pH, water temperature, and specific conductance at 45 sites in and adjacent...
Pesticides in the nation's rivers, 1975-1980, and implications for future monitoring
Robert J. Gilliom, Richard B. Alexander, Richard A. Smith
1985, Water Supply Paper 2271
Water samples were taken four times per year and bed-sediment samples two times per year during 1975-80 at 160 to 180 stations on major rivers of the United States. Samples were analyzed for 18 insecticides and 4 herbicides, which together accounted for about one-third of the total amount of all...
Analyses of flood-flow frequency for selected gaging stations in South Dakota
R.D. Benson, E.B. Hoffman, V.J. Wipf
1985, Water-Resources Investigations Report 85-4217
Analyses of flood flow frequency were made for 111 continuous-record gaging stations in South Dakota with 10 or more years of record. The analyses were developed using the log-Pearson Type III procedure recommended by the U.S. Water Resources Council. The procedure characterizes flood occurrence at a single site as a...
Low flows and flow duration of Tennessee streams through 1981
R.H. Bingham
1985, Water-Resources Investigations Report 84-4347
Estimates of low-flow characteristics and flow duration for the period of record at continuous-record streamflow gages are essential in hydrologic studies and water-resources management. This report provides estimates of low flow for 1, 3, 7, 14, 30, 60, and 90 consecutive days for recurrence intervals of 2, 5, 10 ,...
Chemical and isotopic characteristics of brines from three oil- and gas-producing sandstones in eastern Ohio, with applications to the geochemical tracing of brine sources
K. J. Breen, Clifford G. Angelo, Robert W. Masters, Alan C. Sedam
1985, Water-Resources Investigations Report 84-4314
Chemical and isotopic characteristics of selected inorganic constituents are reported for brines from the Berea Sandstone of Mississippian age, the Clinton sandstone, Albion Sandstone of Silurian age, and the Rose Run formation of Cambrian and Ordovician age in 24 counties in eastern Ohio. Ionic concentrations of dissolved constituents in brines...
Bibliography of borehole geophysics as applied to ground-water hydrology
Ticie A. Taylor, Joyce A. Dey
1985, Circular 926
Most of the references on borehole geophysics that are relevant to ground-water hydrology are contained in this bibliography, but it does not include every reference that is available under each subject heading; the literature is much too extensive to compile a complete listing. Some of the references may appear under...
Geochemical survey of the Devil's Den Roadless Area, Rutland and Windsor counties, Vermont
J. F. Slack, P.J. Atelsek, A. E. Grosz
1985, Miscellaneous Field Studies Map 1626-C
The Devils Den Roadless Area comprises 8,830 acres of mountainous terrane in the Green Mountain National Forest, Rutland and Windsor Counties, Vt. (Index Map). Ludlow, the nearest large community, is approximately 7 air miles northeast of the study area. The small villages of Weston and East Wallingford are 3 to...
Low-flow characteristics of streams in the Kishwaukee River basin, Illinois
Howard E. Allen Jr., Ellen A. Cowan
1985, Water-Resources Investigations Report 84-4311
Seven-day, 2-year, and 7-day, 10-year natural low flows are estimated at five continuous-record gaging stations based on streamflow records and records of wastewater effluent furnished by treatment plants. Low flows are also estimated at 22 partial-record stations by relating natural low-flow estimates for long-term stations to discharge measurements at partial-record...
Paleomagnetic investigations at Mahd adh Dhahab, Kingdom of Saudi Arabia
M. E. Gettings
1985, Open-File Report 85-15
Paleomagnetic studies of 25 oriented bedrock specimens from Jabal Mahd adh Dhahab, located 160 km southeast of Al Madinah, Kingdom of Saudi Arabia, have yielded important structural information relating to the geologic history of this base and precious metal deposit. Samples were collected along one traverse away from the mineralized...
Mineral potential of felsic plutonic rocks in the north-central Arabian Shield, Kingdom of Saudi Arabia
W. J. Moore
1985, Open-File Report 85-6
Fourteen plutons of Late Proterozoie age potentially favorable for rare-element mineralization have been identified in a geochemical and petrographic assessment of felsic plutonic rocks in the north-central Arabian Shield (lat 23°00'-25°00' N., long 40°00'-45°00' E.). The plutons are highly fractionated, leucocratic granitoids assigned to a major magmatic pulse that spanned...
