Mineral resource potential map of the James River Face Wilderness, Bedford and Rockbridge counties, Virginia
C. Erwin Brown, Gertrude C. Gazdik
1982, Miscellaneous Field Studies Map 1337-D
The rocks in the James River Face Wilderness are shales and quartzites that overlie a meta-igneous basement. They are folded into a large southwestward-plunging anticline that is cut off on the east and south by an extensive thrust fault that brings old basement rocks over the younger sedimentary rocks. Geochemical...
Generalized altitude and configuration of the water table in parts of Larimer, Logan, Sedgwick, and Weld Counties, Colorado
Ronald G. Borman, Neville G. Gaggiani
1982, Water-Resources Investigations Report 82-4055
The water table in parts of Larimer, Logan, Sedgwick, and Weld Counties, Colorado ranges from about 7,000 feet above the National Geodetic Vertical Datum of 1929 (formerly called mean sea level) in eastern Larimer County to about 3,450 feet in northeastern Sedgwick County. Water is moving to the south and...
A geochemical survey using heavy mineral concentrates in the Mount Belknap caldera vicinity, Utah
R. E. Tucker, W. Roger Miller, J. M. Motooka
1982, Open-File Report 82-602
Geochemical surveys of the rocks, heavy-mineral concentrates, and surface and spring waters in the vicinity of the Mount Belknap caldera, Tushar Mountains, west-central Utah, were conducted during the summers of 1978 and 1979. Anomalous concentrations of mostly lithophile elements, particularly niobium, beryllium, lead, yttrium, tin, zinc, manganese, and molybdenum in...
Annotated report and data inventory for the Mississippi and Minnesota rivers, Minneapolis-St. Paul metropolitan area
T. A. Winterstein
1982, Open-File Report 82-869
This inventory of reports and data concerning the Mississippi and Minnesota Rivers in the Twin Cities metropolitan area was compiled from November 1981 through January 1982 for a planned river-quality assessment to be conducted cooperatively by the U.S. Geological Survey and the Metropolitan Waste Control Commission. There are 260 annotated...
Performance assessments for radioactive waste repositories; the rate of movement of faults
Newell J. Trask
1982, Open-File Report 82-972
Performance assessments of mined repositories for radioactive waste require estimates of the likelihood of fault movements and earthquakes that may affect the repository and its surrounding ground water flow system. Some previous assessments have attempted to estimate the rate of formation of new faults; some have relied heavily on historic...
Selected climatic characteristics of the southeastern Uinta Basin, Utah and Colorado
S. D. Waltemeyer
1982, Open-File Report 82-91
The southeastern Uinta Basin in Utah and Colorado contains large reserves of oil shale, the mining of which could affect the area 's water resources. Climatic characteristics of the area, which were evaluated as one phase of a comprehensive hydrologic study, are presented to help provide the means of evaluating...
Saturated thickness of the High Plains regional aquifer in 1980, northwestern Oklahoma
John S. Havens
1982, Open-File Report 82-760
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
