Late Paleozoic depositional trends in the central Appalachian Basin
Kenneth J. Englund, Roger E. Thomas
1990, Bulletin 1839-F
Trends in the regional extent, stratigraphical distribution, and character of upper Paleozoic terrestrial rocks in the central Appalachian basin were influenced by depositional events associated with basin evolution. Most of these rocks originated as siliciclastic detritus eroded from tectonic highlands that were elevated by plate collision along the southeastern margin...
Microbanded manganese formations; protoliths in the Franciscan Complex, California
J. Stephen Huebner, Marta J. Flohr
1990, Professional Paper 1502
The Buckeye manganese deposit, 93 km southeast of San Francisco in the California Coast Ranges, preserves a geologic history that provides clues to the origin of numerous lenses of manganese carbonate, oxides, and silicates that occur with interbedded radiolarian chert and metashale of the Franciscan Complex. Compositionally and mineralogically laminated...
Hydrologic data collected in the vicinity of the proposed gamma-ray and neutrino detector site, Hot Spring County, Arkansas, 1988-89
D. J. Fitzpatrick, P.W. Westerfield
1990, Open-File Report 89-623
An abandoned barite mine in Hot Spring County, Arkansas, has been selected as the location for a proposed gamma-ray and neutrino detector site. As part of the hydrologic evaluation of the site, the U.S. Geological Survey in cooperation with the Arkansas Geological Commission collected hydrologic data at selected locations in...
Water-resources programs and hydrologic-information needs, Marion County, Indiana, 1987
R.F. Duwelius
1990, Open-File Report 90-159
Water resources are abundant in Marion County, Indiana, and have been developed for public and industrial supply, energy generation, irrigation, and recreation. The largest water withdrawals are from surface water, and the two largest water uses are public supply and cooling water for electrical-generating plants. Water-resources programs in the county...
Ground-water flow in the Gulf Coast aquifer systems, south central United States — A preliminary analysis
A. K. Williamson, H. F. Grubb, J. S. Weiss
1990, Water-Resources Investigations Report 89-4071
A major objective of the Gulf Coast Regional Aquifer-System Analysis is to use digital models of regional groundwater flow systems to develop better understanding and to improve management of the resource. Modeling is used to synthesize information about the aquifer systems and to test hypotheses about the relative importance of...
Water resources data, Massachusetts and Rhode Island, water year 1988
R. A. Gadoury, R.S. Socolow, R.W. Bell, T.J. Calderini
1990, Water Data Report MA-RI-88-1
Water-resources data for the 1988 water year for Massachusetts and Rhode Island consists of stage, discharge and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 94 gaging stations, month end contents for 20 lakes and reservoirs, water quality for 9...
