Reconnaissance geologic map of the Jabal Zain Quadrangle, sheet 20/44A, Kingdom of Saudi Arabia
Maurice R. Brock
1983, Open-File Report 83-639
Late Precambrian rocks of the Jabal Zain quadrangle comprise two distinct terranes separated by a broad cataclastic zone that formed during the latest Precambrian Najd strike-slip faulting. Only minor gold-silver prospects have been located in the quadrangle, and the potential for larger depostts is considered low. North of the Najd fault...
Summaries of technical reports, volume XVII
Muriel L. Jacobson (compiler)
1983, Open-File Report 83-918
The research results described in the following summaries were submitted by the investigators on October 20, 1983 and cover the 6-month period from April 1, 1983 through September 30, 1983. These reports include both work performed under contracts administered by the Geological Survey and work by members of the Geological...
Drainage-area data for Wisconsin streams
E.W. Henrich, D.N. Daniel
1983, Open-File Report 83-933
Drainage areas were determined for more than 7,000 sites in Wisconsin's 11 major river basins, including all named streams draining 5 or more square miles, and all unnamed streams draining 10 or more square miles. Also determined are drainage areas for gaging stations, sewage-treatment plants, dams, major highway crossings, and...
Slides showing aeromagnetic and gravity data for regional mineral exploration in Colorado, New Mexico, and Arizona
Douglas P. Klein
1983, Open-File Report 83-443
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....
Discharge data at water-quality monitoring stations in Arkansas, 1981 water year
R.K. Knott
1983, Open-File Report 83-214
Discharge data were computed for a network of water-quality monitoring stations operated by the Arkansas Department of Pollution Control and Ecology (ADPC and E). All stations in the network were visited by Geological Survey personnel. Discharges on days of sampling were determined for 83 of the sites. A summary table...
A description of aquifer units in western Oregon
W. D. McFarland
1983, Open-File Report 82-165
Hydrogeologic information for western Oregon was compiled to aid the U.S. Environmental Protection Agency in evaluating proposals for underground injection of waste fluid. Geologic formations were grouped into seven aquifer units according to hydraulic and geologic similarities. The bedrock aquifer units in the Klamath Mountains, Coast Range, and Western Cascade...
Submarine canyon and slope processes of the U.S. Atlantic continental margin
B.A. McGregor
1983, Open-File Report 83-735
Two regions on the U.S. Atlantic continental margin were surveyed using single-channel, seismic-reflection profiling techniques: the Mid-Atlantic Continental Slope and Rise seaward of New Jersey in the vicinity of Baltimore Canyon and the Continental Slope and upper Rise just north of Cape Hatteras. Submarine canyons are the dominant morphologic feature...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: December 1983
John B. Townshend, J.E. Papp, E.A. Sauter, P.A. Franklin, L.Y. Torrence
1983, Open-File Report 83-300-L
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
