Mineral resources of the Big Frog Wilderness Study Area, Polk County, Tennessee and Fannin County, Georgia
John F. Slack, Gertrude C. Gazdik, Maynard L. Dunn
1979, Open-File Report 79-1209
The proposed Big Frog Wilderness is comprised of approximately 1820 hectares (18.2 km2) of mountainous terrain in the Cherokee and Chattahoochee National Forests south of the Ocoee River in Polk County, Tennessee, and Fannin County, Georgia. Rocks of the study area are greenschist-facies metasandstone, meta-arkose, metagraywacke, and dark slate of...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Big Delta quadrangle, Alaska
Helen Laura Foster, N. R. D. Albert, Andrew Griscom, T. D. Hessin, W. D. Menzie, D. L. Turner, Frederic H. Wilson
1979, Circular 783
The geology, geochemistry, geophysics, and Landsat imagery of the Big Delta quadrangle, 16,335 km 2 in the Yukon-Tanana Upland of east-central Alaska, were investigated, and maps and reports were prepared by an interdisciplinary research team for the purpose of assessing the mineral potential. The quadrangle is dominantly a complex terrane...
The Alaskan Mineral Resource Assessment Program: Guide to information contained in the folio of geologic and mineral resource maps of the Chandalar quadrangle, Alaska
H. N. Reiser, W. P. Brosge, J. H. DeYoung, S.P. Marsh, T. D. Hamilton, J. W. Cady, N. R. D. Albert
1979, Circular 758
The Chandalar quadrangle in east-central Alaska was investigated by a multidisciplinary research group to assess the mineral resource potential of the quadrangle. This circular serves as a guide to and integrates with a folio of 10 miscellaneous field study (MF) maps and 2 open-file (OF) reports (table 1) concerned with...
A facility designed to monitor the unsaturated zone during infiltration of tertiary-treated sewage, Long Island, New York
Robert C. Prill, Edward T. Oaksford, James E. Potorti
1979, Water-Resources Investigations Report 79-48
A facility consisting of a circular recharge basin 6.10 meters in diameter with a central observation manhole was developed on Long Island, N.Y., to study the role of the unsaturated zone during aquifer recharge with tertiary-treated sewage. The manhole extends through most of the 7.5-meter-thick unsaturated zone, which is composed...
Biological and microbiological assessment of the upper Chattahoochee River basin, Georgia
Bruce W. Lium, J. K. Stamer, T. A. Ehlke, R.E. Faye, R.N. Cherry
1979, Circular 796
Biological and microbiological studies were conducted by the U.S. Geological Survey as a part of the Intensive River-Quality Assessment studies of the upper Chattahoochee River basin, Georgia. Phytoplankton concentrations in cells per milliliter (cells/mL) were generally higher downstream from Atlanta than upstream. The highest concentrations, mostly blue-green algae, occurred in...
Earth fissures and localized differential subsidence
Thomas L. Holzer, Earl Haig Pampeyan
1979, Open-File Report 79-951
Long tension cracks caused by declines of ground-water level at four sites in Arizona, California, and Nevada occur at points of maximum, convex-upward curvature in subsidence profiles based on relevelings of closely-spaced bench marks aligned perpendicular to the cracks. We conclude the cracks are caused by horizontal strains associated with...
System dynamics simulation modeling applied to western coal development environmental impact analysis
R. K. Mark, D. S. Harwood, E. B. Newman, Richard R. Doell
1979, Open-File Report 79-226
This report, which was originally prepared in 1977 as an administrative report, evaluates the Geological Survey's first attempt to use simulation modeling in the environmental impact statement (EIS) process. It discusses the background of the modeling project, evaluates the usefulness of that project to the Northern Powder River Basin regional...
Arsenic, nitrate, iron, and hardness in ground water, Fairbanks area, Alaska
Paula R. Johnson, D.E. Wilcox, W.D. Morgan, Josephine Merto, Ruth McFadden
1979, Open-File Report 78-1034
Well water with concentrations of arsenic and nitrate exceeding U.S. Environmental Protection Agency standards occurs sporadically throughout the hills north of Fairbanks, Alaska. The arsenic contamination has not been correlated with placer or other mining activity. The high levels of nitrate do not generally appear related to septic waste contamination....
Physical, chemical, and biological characteristics of Ross Lake, Snohomish County, Washington
N. P. Dion
1979, Water-Resources Investigations Report 78-44
A study of the physical, chemical, and biological characteristics of Ross Lake in 1975 showed that the lake has no well-defined surface-water inflow and that thermal stratification is well established in summer. The water is of a calcium bicarbonate type, which is typical of lakes in western Washington.Biological productivity in...
Summary report of the sediments, structural framework, petroleum potential, and environmental conditions of the United States Mid-Atlantic continental margin in area of proposed Oil & Gas Lease Sale No. 59
John Stevens Schlee, Robert E. Mattick, Richard B. Powers, James M. Robb, David C. Twichell, Bradford Butman
1979, Open-File Report 79-1351
This report has been compiled to update and summarize the geological information concerning the area of the Atlantic continental margin off the U.S. Mid-Atlantic proposed for Oil and Gas Lease Sale No. 59 (fig. 1). The region of interest lies between 35° and 41° N and 70.5° and 76° W....
Approximate altitude of water levels in wells in the Chicot and Evangeline aquifers in the Houston area, Texas, Spring 1977 and Spring 1978
R.K. Gabrysch
1979, Open-File Report 79-334
The purpose of this report, which was prepared in cooperation with the cities of Houston and Galveston, the Harris-Galveston Coastal Subsidence District, and the Texas Department of Water Resources, is to show the altitudes of water levels in wells in the Chicot and Evangeline aquifers in the Houston, Texas, metropolitan...
