Geochemical prospecting for Carlin-type gold deposits
Sherman P. Marsh
1976, Open-File Report 76-335
Disseminated, Carlin-type, gold deposits are associated with a volatile suite of elements consisting of Hg, As, Sb, W, and sometimes, but not always, Au. Geochemical exploration for this type of disseminated deposit depends upon recognizing the significance of this volatile suite and interpreting it in light of other geologic and...
Analog-model analysis of effect of wastewater management on the ground-water reservoir in Nassau and Suffolk Counties, New York: Report I: Proposed and current sewerage
Grant E. Kimmel, Arlen W. Harbaugh
1976, Open-File Report 76-441
By 1995, the water table may fall by as much as 5 metres (16 feet) in east-central Nassau County and as much as 1.8 metres (6 feet) in central Suffolk County as a result of proposed sewerage programs. similar, but generally slightly less, change may occur in the potentiometric head...
Water-quality data for the Southern Ute Indian Reservation, southwestern Colorado
E. Carter Hutchinson, Robert E. Brogden
1976, Open-File Report 76-16
Water-quality data from a study by the U.S. Geological Survey on the Southern Ute Indian Reservation in southwestern Colorado are presented in two tables. The data were collected during 1973-76 from 338 ground-water and surface-water samples. All samples were analyzed for major catons and anions, and selenium and arsenic. Data...
Evaluation of hydrologic properties of the Long Island ground-water reservoir using cross-sectional electric-analog models
O.L. Franke, R.T. Getzen
1976, Open-File Report 75-679
Variables necessary for constructing a quantitative model to predict the response of ground-water reservoirs to hydrologic stresses are in four classes: (a) external and internal geometry of the reservoir, (b) nature of the reservoir boundaries, (c) areal distribution of horizontal and vertical hydraulic conductivities, and (d) areal distribution of storage...
Summary appraisals of the nation's ground-water resources – Arkansas-White-Red region
M. S. Bedinger, R. T. Sniegocki
1976, Professional Paper 813-H
The Arkansas-White-Red Region, an area of265,000 square miles (6.86x1011 square metres), is characterized by diversity in geography, climate, and geology and, in turn, by diversity in water resources and water problems. The western semiarid part of the region is water deficient, that is, potential evapotranspiration exceeds precipitation. The eastern, humid part...
Preliminary overview map of volcanic hazards in the 48 conterminous United States
D. R. Mullineaux
1976, Miscellaneous Field Studies Map 786
Volcanic eruptions and related phenomena can be expected to occur in the Western United States, and in some places are potentially hazardous enough to be considered in longe-range land-use planning. But the immediate risk from volcanic hazards is low because eruptions are so infrequent in the conterminous United States that...
