Bouguer gravity map of Alaska
David F. Barnes
1976, Open-File Report 76-70
The Bouguer gravity map of Alaska has been compiled from about 30,000 Alaska land gravity measurements plus approximately 40,000 km of surface-ship gravimeter traverses over the bordering continental shelves. The compilation thus represents nearly three times as much land data and ten times as much marine data as were available...
Uranium in the Cochetopa District, Colorado, in relation to the Oligocene erosion surface
Jerry Chipman Olson
1976, Open-File Report 76-222
In the Cochetopa district, Colorado, the sequence of Mesozoic and Cenozoic events is as follows: development of a relatively smooth, planar erosion surface in Jurassic time; deposition, on this surface, of the Junction Creek Sandstone and Morrison Formation of Jurassic age, followed by deposition of the Dakota Sandstone and Mancos...
Geological Survey and selected U.S. Bureau of Mines and Alaska Division of Geological and Geophysical Surveys reports and maps on Alaska released during 1975, indexed by quadrangle
Edward Huntington Cobb
1976, Open-File Report 76-332
All Geological Survey reports and maps on Alaska published or released to open files during 1975 are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 3). Also listed are U.S. Bureau of Mines reports on the geology and mineral resources of Alaska,...
Low-flow study of the Pike River Basin, Racine and Kenosha counties, Wisconsin
Stephen J. Field
1976, Open-File Report 75-653
The low-flow characteristics of the Pike River basin, Racine and Kenosha Counties were studied to determine the feasibility of Public Law 566 watershed-protection practices. Two seepage runs, one in October 1973, and the other in September 1974, showed that most of the low flow is combined treated-sewage and industrial cooling-water...
Integration of geological remote-sensing techniques in subsurface analysis
James V. Taranik, Charles M. Trautwein
1976, Open-File Report 76-402
Geological remote sensing is defined as the study of the Earth utilizing electromagnetic radiation which is either reflected or emitted from its surface in wavelengths ranging from 0.3 micrometre to 3 metres. The natural surface of the Earth is composed of a diversified combination of surface cover types, and geologists...
Preliminary investigation of the elemental variation and diagenesis of a tabular uranium deposit, La Sal Mine, San Juan County, Utah
Robert A. Brooks, John A. Campbell
1976, Open-File Report 76-287
Ore in the La Sal mine, San Juan County, Utah, occurs as a typical tabular-type uranium deposit of the-Colorado Plateau. Uranium-vanadium occurs in the Salt Wash Member of the Jurassic Morrison Formation. Chemical and petrographic analyses were used to determine elemental variation and diagenetic aspects across the orebody. Vanadium is...
A summary of petroleum potential, environmental geology, and the technology, time frame, and infrastructure for exploration and development of the western Gulf of Alaska
Roland E. von Huene, Arnold H. Bouma, George Moore, Monty A. Hampton, Rodney Smith, Gordon Dolton
1976, Open-File Report 76-325
This summary of the regional geology, petroleum potential, geologic hazards and time frame for exploration of the western Gulf of Alaska has been written to aid the Bureau of Land Management in preparing the Draft Environmental Impact Statement. A preliminary version was written in Sept., 1975.(von Huene and others, 1975)...
