Water quality of Indian Creek-Van Buren watershed, Iowa and Missouri
Larry J. Slack, Mark G. Detroy
1980, Open-File Report 80-677
Generally, the water quality of Indian Creek-Van Buren watershed is suitable as a source of Municipal, industrial and agricultural water supply and for fish and wildlife. This suitability is based upon comparisons of the existing water quality of Indian Creek to Federal and State water quality standards and criteria developed for the protection of water sources...
Chemical character of water in the Red River alluvial aquifer, Louisiana
M.S. Whitfield
1980, Open-File Report 80-1018
The Red River alluvial aquifer of Louisiana underlies approximately 2,000 square miles in the Red River Valley of Louisiana. The aquifer is Pleistocene in age and consists of clay, silt, sand, and gravel deposited by the Red River. Sand and gravel constitute the lower two-thirds of the deposit, the most...
Lemhi Pass drilling project, Montana
Mortimer Hay Staatz
1980, Open-File Report 80-312
The Lemhi Pass district has the largest thorium resources of any vein district in the United States (Staatz and others, 1979, p. 10). Most of the resources occur in veins that have an average grade of between 0.1 and 2.0 percent Th02. More than 200 thorium-bearing veins have been mapped...
Simulated effects of ground-water development on potentiometric surface of the Floridan Aquifer, west-central Florida
William Edward Wilson, James M. Gerhart
1980, Open-File Report 79-1271
A digital model of two-dimensional ground-water flow was used to predict changes in the potentiometric surface of the Floridan aquifer, 1976-2000, in a 5,938-square-mile area of west-central Florida. In 1975, ground water withdrawn from the Floridan aquifer for irrigation, phosphate mines, other industries, and municipal supplies averaged about 649 million...
Summary of data available for Morocco as of June 10, 1977
Glen F. Brown
1980, Open-File Report 80-520
Structurally, Morocco is partly European (Alpine and Hercynian) and partly the northwestern flank of the African platform. It includes a variety of land forms and structural provinces, each strikingly different from adjacent domains....
Chemical analyses of stream deposits in the West Pioneer Mountains, Beaverhead County, Montana
David F. Siems, Eric P. Welsch, Wendy S. Speckman
1980, Open-File Report 80-309
The U.S. Geological Survey commenced a mineral-resource assessment of the West Pioneer Mountains, Montana in 1970. The study consists of coordinated geological, geochemical, and geophysical studies with the objective of evaluating the potential for mineral deposits in the area. The geochemical survey consists of the collection of bulk stream sediments...
Biological premonitors of earthquakes: A validation study
Leon Spelly Otis, W.H. Kautz
1980, Open-File Report 80-1152
For the greatest ultimate usefulness to society, the two most important facets of earthquake prediction are (1) a fundamental scientific understanding of the earthquake-triggering process and (2) the identification of reliable and measurable premonitors. A possible approach to both of these problem areas, and one that has received almost no...
A preliminary appraisal of the effects of agriculture on stream quality in southwest Georgia
Dean B. Radtke, James B. McConnell, William P. Carey
1980, Open-File Report 80-771
Water—quality and suspended—sediment samples were collected in two basins in southwest Georgia to determine whether water—quality problems have resulted from agricultural practices. Samples were collected monthly and during periods of storm runoff from December 1976 through July 1978. Concentrations of chemical constituents relevant to agricultural practices were found to be...
Seismic refraction data for shots recorded in the Coso Range, California, October 1976
A. W. Walter, Craig S. Weaver
1980, Open-File Report 80-186
The Coso Range lies in the southwest corner of the Basin and Range province, east of the Sierra Nevada and north of the Garlock Fault. The range, circular in form, is covered by a thin sequence of late-cenozoic volcanics which overlie highly fractured crystalline basement, similar in composition to the...
