United States Geological Survey Alaska Program, 1975
M. E. Yount, editor(s)
1975, Circular 722
This report on the Alaskan activities of the U.S. Geological Survey contains up-to-date accounts of recent results and summaries of plans for the summer of 1975. It is organized in six parts: (1} responsibilities and services of the Geological Survey; (2} organization of the U.S. Geological Survey; (3) U.S. Geological...
The Alaskan mineral resource assessment program; background information to accompany folio of geologic and mineral resource maps of the Nabesna Quadrangle, Alaska
Donald H. Richter, N. R. D. Albert, D.F. Barnes, Andrew Griscom, S.P. Marsh, D.A. Singer
1975, Circular 718
The Nabesna quadrangle in south-central Alaska is the first of the l:250,000-scale Alaskan quadrangles to be investigated by an interdisciplinary research team in order to furnish a mineral resource assessment of the State. The assessment of the 17,600-km 2 16,800-mi21 quadrangle is based on field and laboratory investigations of the...
Preliminary report on the reconnaissance engineering geology of the Yakutat area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Lynn A. Yehle
1975, Open-File Report 75-529
Yakutat, situated about 225 miles northwest of Juneau, Alaska, near the shores of the Gulf of Alaska, has a setting that calls for superlatives. Within the Yakutat region are some of the tallest mountains, some of the heaviest snowfalls, and the largest glacier in North America. Between the abrupt mountain...
U, Th, and K analyses of selected plutonic rocks from west-central Alaska
Thomas P. Miller, Carl M. Bunker
1975, Open-File Report 75-216
Numerous samples of plutonic rocks collected during reconnaissance mapping in western Alaska have been analyzed for K, U, and Th. The U and Th content of the plutonic rocks from the southeastern Seward Peninsula have been discussed in a separate report (Miller and Bunker, 1975); because of the current interest...
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...
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...
Experimental results of atomic absorption analyses for indium and thallium in 803 nonmagnetic concentrates from Alaska
William C. Overstreet, George L. Crenshaw, Arthur E. Hubert, Sam Rosenblum, Ricke J. Smith
1975, Open-File Report 75-253
The development in the U.S. Geological Survey of rapid methods for the determination by atomic absorption spectrophotometry of indium and thallium at limits of detection as low as 0.2 ppm each in geologic materials affords great advantages over spectrographic methods in studies concerned with values at or near the crustal...
Geological Survey and selected U.S. Bureau of Mines and Alaska Division of Geological and Geophysical Surveys reports and maps on Alaska released during 1974, indexed by quadrangle
Edward Huntington Cobb
1975, Open-File Report 75-128
All Geological Survey reports and maps on Alaska published or released to open files during 1974 are listed by the quadrangle (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). Also listed are U.S. Bureau of Mines reports on the geology and mineral resources of Alaska,...
Interim report on petroleum resource potential and geologic hazards in the outer continental shelf of the Gulf of Alaska Tertiary province
George Plafker, Terry R. Bruns, Robert A. Page
1975, Open-File Report 75-592
The potential for discovering large accumulations of petroleum on the Outer Continental Shelf of the Gulf of Alaska Tertiary Province cannot be evaluated with much confidence at present because of the inadequacies of the available offshore geological and geophysical data. The 22 deep test wells that have been drilled since...
Hydrology for land-use planning: The Hillside area, Anchorage, Alaska
Larry L. Dearborn, William W. Barnwell
1975, Open-File Report 75-105
Rapid residential growth of the Hillside area, Anchorage, Alaska, may cause depletion of aquifers and a change in quality of water resources as a result of extensive development of small-lot tracts. Ground-water yields are low and may be locally inadequate for single family requirements where wells produce from bedrock in...
Petrography of University of Washington dredge samples for the central Chukchi Sea
Jeremy B. Platt
1975, Open-File Report 75-269
Twenty thin sections of rocks dredged from the central Chukchi Sea have been examined petrographically and compared with some onshore rocks in northern Alaska. Of these, 16 are sandstones, three are highly CaCO3-rich silts and carbonate rocks, and one is an olivine-magnetite-rich basalt. Eight of the sandstones have been point-counted...
Reconnaissance engineering geology of the Ketchikan area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard W. Lemke
1975, Open-File Report 75-250
The Alaska earthquake of March 27, 1964, dramatically emphasized the need for engineering geologic studies of urban areas in seismically active regions. A reconnaissance study of the Ketchikan area in southeastern Alaska is part of a program to evaluate earthquake and other geologic hazards in most of the larger Alaska...
Geologic framework of the Alaskan Continental Terrace in the Chukchi and Beaufort seas
Arthur Grantz, Mark L. Holmes, B. A. Kososki
1975, Open-File Report 75-124
Seismic, magnetic and gravity data indicate that the Chukchi and Beaufort epicontinental seas off northern Alaska overlie three sedimentary basins, or provinces, separated by structural highs of regional extent. The basins trend west to northwest and become increasingly marine from south to north. The Chukchi-Beaufort continental margin is similar to...
