A summary report of the regional geology, environmental geology, OCS resource appraisal, petroleum potential, and operational considerations in the area of proposed lease sale 73, offshore California
David S. McCulloch
1980, Open-File Report 80-2007
This report reviews geological, geophysical and technological data pertinent to proposed Lease Sale 73. Under consideration is the entire continental margin of California that is bounded on the west by the 2500 meter isobath. This area encompasses the whole of the southern California Borderland, the continental shelves of central and...
Catalog of earthquakes in southern Alaska, January-March 1980
C.D. Stephens, K.A. Fogleman, J.C. Lahr, S.M. Helton, R.S. Cancilla, Roy Tam, J.A. Freiberg
1980, Open-File Report 80-1253
The National Center for Earthquake Research of the U.S. Geological Survey (USGS) began a program of telemetered seismic recording in south-central Alaska in 1971. The principal objectives of this program have been to use data recorded by this network to precisely locate earthquakes in the active seismic zones of southern...
A summary of environmental geologic studies in the Georges Bank area, United States northeastern Atlantic Outer Continental Shelf, 1975-1977
John M. Aaron
1980, Open-File Report 80-241
The growing need for the United States to find and develop new energy resources has led to interest in the petroleum potential of frontier areas of the Atlantic Outer Continental Shelf (OCS) seaward of the eastern seaboard state boundaries. These submerged lands are under federal jurisdiction. The authority to lease...
Floods in the Raccoon River basin, Iowa
Albert J. Heinitz
1980, Open-File Report 80-162
Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains requires information on floods. This report provides information on flood stages and discharges, flood magnitude and frequency, bench mark data, and flood profiles for the Raccoon River and some of its tributaries. It covers...
Notes on the geology of Tibet and adjacent areas; report of the American plate tectonics delegation to the People's Republic of China
A.W. Bally, Clarence R. Allen, R.B. Geyer, W.B. Hamilton, C.A. Hopson, P.H. Molnar, J.E. Oliver, N.D. Opdyke, George Plafker, F.T. Wu
1980, Open-File Report 80-501
Mean water levels in wells across Georgia were from 3.03 feet higher to 11.67 feet lower in 1979 than in 1978, and in some areas were the lowest on record. Water levels in the principal artesian aquifer underwent a long-term decline during the period 1970-79. In some areas water levels...
Water resources of the Cook Inlet Basin, Alaska
Geoffrey W. Freethey, David R. Scully
1980, Hydrologic Atlas 620
Ground-water and surface-water systems of Cook Inlet basin, Alaska, are analyzed. Geologic and topographic features that control the movement and regional availability of ground water are explained and illustrated. Five aquifer systems beneath the most populous areas are described. Estimates of ground-water yield were determined for the region by using...
Potentiometric map of the Meridian-Upper Wilcox Aquifer in Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-590
The potentiometric map of the Meridian-upper Wilcox aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources, Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area...
Rubidium-strontium geochronology and plate-tectonic evolution of the southern part of the Arabian Shield
Robert J. Fleck, W.R. Greenwood, D.G. Hadley, R.E. Anderson, D. L. Schmidt
1980, Professional Paper 1131
Rubidium-strontium studies of Precambrian volcanic and plutonic rocks of the Arabian Shield document an early development of the Arabian craton between 900 and 680 m.y. (million years) ago. Geologic studies indicate an island-arc environment characterized by andesitic (dioritic) magmas, volcaniclastic sedimentation, rapid deposition, and contemporaneous deformation along north or northwest-trending...
