Numerical model of the salt-wedge reach of the Duwamish River estuary, King County, Washington
Edmund A. Prych, W.L. Haushild, J.D. Stoner
1975, Open-File Report 75-13
A numerical model of a salt-wedge estuary developed by Fischer has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentrations, biochemical oxygen demand, and dissolved-oxygen concentrations in the Duwamish River estuary, King County, Wash. With this model, which was calibrated and verified with observed data,...
Water availability of Blount County, Alabama
Robert J. Faust, Joe R. Harkins
1975, Open-File Report 75-453
Ground water is obtained mostly from limestone and dolomite aquifers along the Sequatchie anticline and Murphrees Valley anticline and. from sandstone aquifers in Sand Mountain and Blount Mountain synclinal areas. Wells tapping some limestone and dolomite aquifers produce as much as 1.4 mgd (million gallons per day). Wells completed in...
Heavy-mineral trends in the Beaufort Sea
Gretchen Luepke
1975, Open-File Report 75-667
Sediments of the Beaufort Sea, off the North Slope of Alaska contain a great variety of heavy minerals. These include garnet, chrome spinel, augite, pigeonite, diopside, hornblende, enstatite, hypersthene, epidote, clinozoisite, zoisite, apatite, tourmaline, chloritoid, sphene, zircon, and opaque minerals. Much rarer constituents are glaucophane, lamprobolite, rutile, kyanite, staurolite, and...
Metallogenic provinces of the southeastern Pacific region
George Edward Ericksen
1975, Open-File Report 75-263
Metalliferous mineral deposits of the southeastern Pacific region include: (1) hydrothermal, magmatic, and sedimentary deposits of the Andean region, one of the great mineral belts of the world; 2) Scattered hydrothermal mineral occurrences in the Antarctic Peninsula; and 3) metal-enriched pelagic sediments, ferromanganese nodules, and volcanic rocks(?) in the southeast...
Airborne gamma-radiation survey of the Jabel Ishmas Quadrangle, Kingdom of Saudi Arabia
Vincent J. Flanigan
1975, Open-File Report 75-190
An airborne gamma-radiation survey system, which includes digital recording and automatic data processing procedures developed by the U. S. Geological Survey Saudi Arabian Project, is used to collect spectral gamma-radiation data as an aid to regional geologic mapping of pediment areas on the Arabian Shield. The areal extent of rock...
Sandstone geometry, porosity and permeability distribution, and fluid migration in eolian system reservoirs
Robert Lupe, Thomas S. Ahlbrandt
1975, Open-File Report 75-357
Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
Sediments, structural framework, petroleum potential, environmental conditions, and operational considerations of the United States North Atlantic Outer Continental Shelf
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-353
The area designated for possible oil and gas lease sale as modified from BLM memorandum 3310 #42 (722) and referred to therein as the North Atlantic Outer Continental Shelf (OCS) contains about 58,300 sq km of shelf beneath water depths of less than 200 m and lies chiefly within the...
Hydrocarbon potential, geologic hazards, and the technology, time-frame and infrastructure for exploration and development of the lower Cook Inlet, Alaska; a preliminary assessment
Leslie B. Magoon, M. A. Hampton, E.G. Sable, R. A. Smith, F.B. Chmelik
1975, Open-File Report 75-549
The Lower Cook Inlet Outer Continental Shelf (OCS) contains 5600 km2 of submerged land in less than 200 m of water 150 to 350 km southwest of Anchorage, Alaska. This area could contain from 0.3 to 1.4 billion barrels of oil and from 0.6 to 2.7 trillion cubic feet of...
