A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Allegheny National Forest, Warren County, Pennsylvania
N. L. Hickling, Stanley P. Schweinfurth, Betty M. Adrian
1983, Open-File Report 83-5
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Warren County, Pennsylvania, was made by members of the U.S. Geological Survey (USGS) to test for indistinct or unexposed mineral deposits that might be recognized by geochemical halos. Analyses using semiquantitative emission spectrography and atomic absorption for...
Water-resources investigations of the U.S. Geological Survey in Kansas; fiscal years 1981 and 1982
J. F. Kenny, L. J. Combs
1983, Open-File Report 83-932
One of the primary missions of the U.S. Geological Survey in Kansas is to investigate the occurrence, quantity, quality, distribution, and movement of surface and groundwater throughout the State. Primary activities include the systematic collection, analysis, and interpretation of hydrologic data, evaluation of water demands, and water-resources research. Hydrologic investigations...
Ground-water data for Georgia, 1982
H.R. Stiles, S.E. Matthews
1983, Open-File Report 83-678
Continuous water level records from 105 wells, and more than 2 ,000 water level measurements made in Georgia during 1982 provided the basic data for this report. Selected wells illustrate the effects that changes in recharge and pumpage have had on the various groundwater resources in the State. Daily mean...
Inventory and analyses of information for flood plain management in North Dakota
D. G. Emerson, J. D. Wald
1983, Open-File Report 84-53
Governmental units that have been identified as having flood hazard areas but do not have detailed base flood information are required to use the "best available data" to regulate new development or expansion of existing development in flood prone areas. Information for flood plain management has been identified for 95...
Laboratory safety handbook
E.L. Skinner, C.A. Watterson, J.C. Chemerys
1983, Open-File Report 83-131
Safety, defined as 'freedom from danger, risk, or injury,' is difficult to achieve in a laboratory environment. Inherent dangers, associated with water analysis and research laboratories where hazardous samples, materials, and equipment are used, must be minimized to protect workers, buildings, and equipment. Managers, supervisors, analysts, and laboratory support personnel...
Streamflow and water-quality data for lake and wetland inflows and outflows in the Twin Cities metropolitan area, Minnesota, 1981-82
Luanne Nelson, R. G. Brown
1983, Open-File Report 83-543
A study of runoff to selected lakes was done in the Twin Cities metropolitan area from July 1981 to December 1982. The purpose of the study was to determine differences in nutrient-loading characteristics for lakes with and without wetlands and settling ponds. The study also quantified nutrient loading to lakes...
In situ geomechanics of crystalline and sedimentary rocks; Part IV, continued field testing of the modified U.S. Geological Survey 3-D borehole stress probe
Thomas C. Nichols
1983, Open-File Report 83-750
Two modified and calibrated U.S. Geological Survey 3-D borehole probes were successfully tested in the field at a site on South Table Mountain, near Golden, Colo. The probes were installed in separate core holes at depths of 84 and 99 cm in the latite cap rock and subsequently stress relieved...
Water quality of Lake Whitney, north-central Texas
Jeffrey L. Strause, Freeman L. Andrews
1983, Open-File Report 82-677
The volume-weighted average concentrations of the major dissolved constituents in Lake Whitney on the Brazos River in north-central Texas usually were less than 1,300 milligrams per liter of dissolved solids, 500 milligrams per liter of chloride, and 300 milligrams per liter of sulfate during the 1970-80 water years. The water...
Hydrologic data for the drainage basins of Chatfield and Cherry Creek Lakes, Denver metropolitan area, Colorado
J. W. Gibbs, L.M. Arnold, R.L. Reed
1983, Open-File Report 83-857
Chatfield and Cherry Creek Lakes are flood control lakes constructed by the U.S. Army Corps of Engineers and leased to the Colorado Division of Parks and Recreation. Both lakes are in the Denver metropolitan area and provide a variety of recreational activities, including boating, camping, fishing, picnicking, and swimming. The...
Middle Tertiary continental rift and evolution of the Red Sea in southwestern Saudi Arabia
Dwight Lyman Schmidt, Donald G. Hadley, Glen F. Brown
1983, Open-File Report 83-641
Middle Tertiary rift volcanism in a continental-rift valley in the Arabian-Nubian Shield was the first surface expression of active mantle convection beneath an axis that was to become the Red Sea. Investigation of the coastal plain of southwestern Saudi Arabia suggests that the rift valley was filled with basaltic and...
The Emma Bell deposit, Siskiyou Co., California: A possible low-grade source of chromite
B. R. Lipin, Nicholas Wetzel, S. M. Heinrich
1983, Open-File Report 83-816
The Emma Bell chromite deposit in Siskiyou County, California contains over 5 million tons of dunite averaging about 4 percent Cr2O3. Chromite is not evenly disseminated throughout the dunite, however. For the most part the deposit consists of many chromite-rich bands in sharp contact with, and separated by, common dunite...
