Surface subsidence and collapse in relation to extraction of salt and other soluble evaporites
John R. Ege
1979, Open-File Report 79-1666
Extraction of soluble minerals, whether by natural or man-induced processes, can result in localized land-surface subsidence and more rarely sinkhole formation. One process cited by many investigators is that uncontrolled dissolving of salt or other soluble evaporites can create or enlarge underground cavities, thereby increasing the span of the unsupported...
Possible uranium mineralization, Mineral Mountains, Utah
W. Roger Miller, John B. McHugh, Walter H. Ficklin
1979, Open-File Report 79-1354
The Mineral Mountains block in west-central Utah is a horst whose core stands structurally high relative to all nearby basin-and-range fault blocks. Rocks of the Mineral Mountains range from Precambrian to Quaternary in age, but mostly consist of Tertiary granitic rocks. The range lies with the Wah Wah-Tusher mineral belt....
Coal geology of the Northeast Circle area, McCone and Dawson counties, Montana
Herbert Wincentsen
1979, Open-File Report 79-1052
The Northeast Circle area is in central McCone and northern Dawson Counties, northeastern Montana. The area encompasses about 940 square miles and has a maximum relief of greater than 1,000 feet. The lowest point (altitude of less than 2,200 feet) is in the Redwater River Valley in the northern part...
Description of dredge samples from the Bering Sea continental margin
Michael S. Marlow, Alan K. Cooper, David W. Scholl, Tracy L. Vallier, Hugh McLean
1979, Open-File Report 79-1139
During 1978 twenty dredge sites were occupied and successfully dredged from the R.V. S.P. LEE along the eastern Bering Sea continental margin (Fig. 1). A total of several tons of rock were collected using a chain-bag dredge. Samples were recovered in water depths ranging from 750 to 2,750 meters from...
An economic analysis of selected strategies for dissolved oxygen management: Chattahoochee River, Georgia
John E. Schefter, Robert M. Hirsch
1979, Open-File Report 79-412
Using the Chattahoochee River as an example, a method for evaluating the cost-effectiveness of alternative strategies for dissolved oxygen (DO) management is demonstrated. The conceptual framework for the analysis is suggested by the economic theory of production. The minimum flow of the River and the percentage of the total waste...
Marine seismic sources, receivers, and recording with reference to the S. P. Lee
Robert Brune, Terry Kelley, Paul Kolling, Al Long, Don Tompkins
1979, Open-File Report 79-1462
During 1975, the Pacific-Arctic Branch of the Office of Marine Geology installed a seismic system onboard the USGS vessel S.P. Lee. The major components of the system include a Bolt 5 air gun array, a 2400 meter SEI streamer, and a GUS high density recording system. Various high resolution/single channel...
