The geological parameters affecting in-situ leaching of uranium deposits
Robert A. Brooks
1979, Open-File Report 79-1238
This report contains material presented at the Uranium Leach Conference, which was held in Vail, Colo., August 25-27, 1976. The purpose of the presentation was to summarize some important geological concepts to a largely nongeological audience involved in the in situ extraction of uranium from buried uranium ore deposits. The...
Terrain corrections for borehole and tower gravity measurements
Larry A. Beyer
1979, Open-File Report 79-721
Many investigators have computed terrain corrections for gravity measurements made in vertical mine shafts (e.g., Rogers, 1952; Domzalski, 1954; Rische, 1957; Vaschilov, 1964) and on structures above ground (e.g., Hammer, 1938; Kumagai et al., 1960; Kuo et al., 1969; Fajklewicz, 1976). The need for a rapid method for calculating terrain...
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....
Surface water environment in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah
Mark William Busby
1979, Open-File Report 79-1499
Streamflows in the lowland areas of the San Juan Basin are highly variable, responding to short-duration, high-intensity thunderstorms occurring in the late spring and summer. The thunderstorms can cause floods of large magnitude, but of localized extent. Most streams of the lowlands are ephemeral or intermittent. Streams of the high...
Grain size, mineralogy, carbon/carbonate content, and age of Miocene and Pliocene samples from dredge hauls, DSDP holes 184B and 185, and the Sandy River Well, southern Bering Sea continental margin and Alaska Peninsula
Michael B. Underwood, T.L. Vallier, J.V. Gardner, J.A. Barron
1979, Open-File Report 79-450
A jointly supported program between the Bureau of Land Management and the U. S. Geological Survey, Pacific-Arctic Branch of Marine Geology was undertaken in the Southern Bering Sea with funds managed by the Outer Continental Shelf Environmental Assessment Program (OCSEAP) Office. This report provides data from analyses that were performed...
Active waste-injection systems in Florida, 1976
John Vecchioli, D.J. McKenzie, C.A. Pascale, W.E. Wilson
1979, Open-File Report 79-1296
As of the end of 1976, seven systems were injecting liquid wastes into Florida's subsurface environment at a combined average rate of 15 million gallons per day. This report presents for each of these systems information on the kind and amount of waste injected and type of pretreatment, construction characteristics...
Chemical analyses of coal from the Tongue River Member of the Fort Union Formation, Moorhead and southeastern part of the northward extension of the Sheridan coal fields, Powder River and Big Horn counties, Montana
Ronald H. Affolter, Joseph R. Hatch, William Craven Culbertson
1979, Open-File Report 79-538
As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 83 samples were collected from 23 core holes in the Paleocene Tongue River Member of the Fort Union Formation in Big Horn and Powder River counties, Montana. These holes...
Geochemical analyses of rock, soil, and stream sediment samples from the Citico Creek Wilderness Study Area, Monroe County, Tennessee
R.T. Hopkins, C. A. Curtis, J. D. Sharkey, J. F. Slack
1979, Open-File Report 79-577
Semiquantitative spectrographic analyses for 31 elements and atomic absorption analyses for gold and zinc on 119 stream sediments, 14 panned concentrates, 128 soils, and 192 rock samples from the Citico Creek Wilderness Study Area and vicinity, Monroe County, Tennessee, are reported here in detail. Locations for all 453 samples are...
A preliminary annotated bibliography on siliceous algal cysts and scales
David P. Adam, Albert D. Mahood
1979, Open-File Report 79-1215
As part of an investigation of the stratigraphic and environmental distributions of siliceous algal resting cysts, we have assembled this bibliography. The emphasis is on papers that illustrate these cysts, and our annotation concentrates on the nature of the illustrations. In some cases, we have also listed taxonomic names of...
Depositional environments of the uranium-bearing Cutler Formations, Lisbon Valley, Utah
John A. Campbell, Brenda A. Steele-Mallory
1979, Open-File Report 79-994
The Cutler Formation in Lisbon Valley, San Juan County, Utah, is composed predominantly of fluvial arkosic sandstones, siltstones, shales, and mudstones that were deposited by meandering streams that flowed across a flood plain and tidal flat close to sea level. Two types of channel deposits are recognized from their sedimentary...
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...
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....
