Mineral deposits and occurrences in the McCarthy Quadrangle, Alaska
E.M. MacKevett Jr.
1976, Miscellaneous Field Studies Map 773-B
The McCarthy quadrangle contains numerous and diverse mineral deposits in various geologic settings. Copper is the dominant mineral commodity, both historically and in terms of potential future production. Gold and silver are the only other metals that have been produced. The metalliferous deposits are concentrated in a northwest-trending belt along...

Flood-Plain Delineation for Cameron Run Basin Water-surface profiles of the 25-, 50-, and 100-year recurrence interval discharges have been computed for all streams and reaches of channels in Fairfax County, Virginia, having a drainage area greater than 1 square mile except for Dogue Creek, Little Hunting Creek, and that part...
Preliminary maps showing ground-water resources in the Lower Colorado River region, Arizona, Nevada, New Mexico, and Utah
S. G. Brown
1976, Hydrologic Atlas 542
This atlas was prepared to meet the need for information on the areal distribution, quantity, and availability of ground water in the lower Colorado River region, an area of about 140,000 square miles in parts of Arizona, Nevada, New Mexico, and Utah. The maps are necessarily generalized in places owing...

Reconnaissance water sampling for radium-226 in central and northern Florida, December 1974-March 1976
G. A. Irwin, C. B. Hutchinson
1976, Water-Resources Investigations Report 76-103
Analyses of 115 water samples collected from December 1974 through March 1976 in eight Florida Counties indicated that 22 samples (19 percent) had radium-226 activities equal to or in excess of 3 piC/liter (picocuries per liter), the concentration limit recommended for drinking water by the U.S. Public Health Service. The...

Regional appraisal of the Wilcox Group in Texas for subsurface storage of fluid wastes: Part 1: Geology
Paul Hastings Jones, P. R. Stevens, J. B. Wasselman, R. H. Wallace Jr.
1976, Open-File Report 76-394
Sandy beds of the Wilcox Group in Texas are underlain and overlain by clays of the Midway and Claiborne Groups. The Wilcox is divided by a persistent shale wedge. Contrasting delta systems described as high-constructive and high-destructive exist in the divisions. Merged high constructive deltas characterize the lower, while the...

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...
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...
