Definitions of components of the Master Water Data Index maintained by the National Water Data Exchange
Robert A. Perry, Charles J. Lewis
1978, Open-File Report 78-183
The Master Water Data Index (MWDI) is a computerized data base developed and maintained by the National Water Data Exchange (NAWDEX). The MWDI contains information about water-data collection sites. This information includes: the identification of sites for which water data are available, the location of these sites, the type of...
Geohydrologic data from twenty-four test holes drilled in the Piceance Basin, Rio Blanco County, Colorado, 1975-76
Frank A. Welder, George J. Saulnier
1978, Open-File Report 78-734
Twenty-four test holes were drilled in the Piceance basin, northwestern Colorado, to obtain geohydrologic data from the Uinta and Green River Formations of Eocene age. Depths of test holes ranged from 640 to 2,800 feet. The maximum quantity of water discharged during the air drilling of individual test holes ranged...
Contact-metasomatic magnetite deposit, Medfra Quadrangle, Alaska
M.L. Throckmorton, William Wallace Patton
1978, Open-File Report 78-26
A small contact-metasomatic magnetite deposit was discovered in the Medfra quadrangle, Alaska, in 1976. It occurs at the contact between a Cretaceous or early Tertiary quartz monzonite stock and Paleozoic limestone and dolomite. The ore is a magnetite-clinohumite-hematite rock that contains up to 60 volume percent magnetite and 76 weight...
Flood-plain delineation for Cub Run basin, Fairfax County, Virginia
Pat LeRoy Soule
1978, Open-File Report 78-17
Flood-plain delineation for Cub Run basin water-surface profiles of the 25-, 50-, and 100-year recurrence interval discharges have been computed for all streams and reaches of channels in Fairfax County, Virginia having a drainage area greater than 1 square mile except for Dogue Creek, Little Hunting Creek, and that part...
Flood-plain delineation for Horsepen Run, Sugarland Run, Nichols Run, Pond Branch, Clarks Branch, and Mine Run Branch basins, Fairfax County, Virginia
Pat LeRoy Soule
1978, Open-File Report 78-1028
Water-surface profiles of the 25-year and 100-year floods and maps on which the 25-, 50-, and 100-year flood boundaries are delineated for streams in the Horsepen Run, Sugarland Run, Nichols Run, and Pond Branch basins are presented in this report.The techniques used in the computation of the flood profiles and...
Chemical quality of water in abandoned zinc mines in northeastern Oklahoma and southeastern Kansas
Stephen J. Playton, Robert Ellis Davis, Roger G. McClaflin
1978, Open-File Report 78-294
Onsite measurements of pH, specific conductance, and water temperature show that water temperatures in seven mine shafts in northeastern Oklahoma and southeastern Kansas is stratified. With increasing sampling depth, specific conductance and water temperature tend to increase, and pH tends to decrease. Concentrations of dissolved solids and chemical constituents in mine-shaft water,...
Notes on the availability of mid-Atlantic multichannel seismic reflection profiles 11 and 12-A, -B, -C, and -D
John Stevens Schlee
1978, Open-File Report 78-474
Available are two multichannel profiles collected by Digicon Geophysical Corporation in 1975 using a 48-channel streamer (3600 m long). and a 27.9 cu. liter air gun array. They were processed in Denver on the Phoenix "I" by William C. Patterson. The processing included demultiplexing and resampling, geometry and common-depth-point definition,...
Mineral resources of the Rock River Canyon Wilderness Study Area, Alger County, Michigan
Jesse William Whitlow, Philip J. Geraci, Peter C. Mory, Elizabeth R. King
1978, Open-File Report 78-527
A mineral resource evaluation of the Rock River Canyon Wilderness Study Area, Alger County, Mich., was completed in 1975 by personnel of the U.S. Geological Survey and the U.S. Bureau of Mines. The area consists of approximately 22 km2 in the Hiawatha National Forest.Rocks exposed in the area include sandstone,...
Scatter diagrams and correlations of uranium in surface water versus discharge, conductivity, and pH at various locations throughout the United States
Jennie L. Ridgley, Karen J. Wenrich-Verbeek
1978, Open-File Report 78-581
A study of the relationship of stream discharge, conductivity, and pH with uranium concentration in surface waters has been made for various locations in the United States utilizing data collected, for the most part, by the U.S. Geological Survey (USGS). The results of the study are portrayed by the scatter...
