Uranium and phosphate resources in the Cooper Formation of the Charleston region, South Carolina
Eric R. Force, G. S. Gohn, L.M. Force, B.B. Higgins
1978, Open-File Report 78-586
Phosphate deposits formerly exploited in the Charleston district were formed by weathering and reworking of the Cooper Formation (Eocene and Oliogcene). Previous workers have shown that unusual concentrations of uranium occur in phosphate-rich nodular material formed during subareal weathering. We found that the old mining district is on an erosional...
Tsunami microprocessor tide system
Harold Clark, Gary L. Heckendorn
1978, Open-File Report 78-95
A Tsunami Microprocessor Tide System was developed to replace the Advanced Tsunami Tide System. The use of microprocessor based systems will reduce manpower and hardware costs from $4,000 per advanced system to $400 per microprocessor system. In addition to the cost reduction; the capacity, capability, and flexibility of the microprocessor...
Hot, deep origin of petroleum: shelf and shallow basin evidence and application
Leigh C. Price
1978, Open-File Report 78-1021
Oil and gas pools in shallow basins or on the shallow, stable shelves of deeper sedimentary basins may not be exceptions to the model of a hot deep origin of petroleum. The oil in shallow basins is directly associated with faulting extending out of the deepest parts of the basin....
Dissolved-oxygen depletion and other effects of storing water in Flaming Gorge Reservoir, Wyoming and Utah
E.L. Bolke
1978, Open-File Report 78-92
The circulation of water in Flaming Gorge Reservoir is caused chiefly by insolation, inflow-outflow relationships, and wind, which is significant due to the geographical location of the reservoir. During 1970-75, there was little annual variation in the thickness, dissolved oxygen, and specific conductance of the hypolimnion near Flaming Gorge Dam....
Water resources of No Name Valley, Colville Indian Reservation, Washington
Denzel R. Cline
1978, Open-File Report 78-122
No Name Creek valley is a trough cut in granitic bedrock in north-central Washington. A low topographic divide in the northern third of the valley separates it into the No Name Creek basin on the south and Omak Creek basin on the north. Omak Creek is the larger stream and...
Estimated oil and gas reserves, Gulf of Mexico Outer Continental Shelf, January 1, 1977
Floyd T. Bryan, John H. Knipmeyer, E. Kenneth Schluntz
1978, Open-File Report 78-87
As of January 1, 1977, nearly 35 trillion cubic feet of gas and about 2.7 billion barrels of oil* are estimated to be the remaining reserves in 294 fields in the Gulf of Mexico Outer Continental Shelf off Texas and Louisiana. Twenty-seven additional fields, discovered since January 1, 1976, in...
Comparison of the Wilfley concentration table and hand panning for concentration of heavy minerals prior to geochemical analysis
William R. Greenwood, M.E. Koesterer, Steve Ludington, Donald A. Risoli
1978, Open-File Report 78-712
Chemical analysis of heavy—mineral concentrates of stream sediments is a common geochemical exploration technique used by the U.S. Geological Survey. Generally these concentrates are prepared by hand panning at streamside or in a washtub and then further concentrated using heavy—liquid (bromoform) techniques in a laboratory. Concentration using heavy liquids is...
