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...
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,...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in five quadrangles in West-Central Alaska (Hughes, Kotzebue, Melozitna, Selawik, Shungnak)
Edward Huntington Cobb
1975, Open-File Report 75-627
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in 5 quadrangles in west-central Alaska. All references to published and open-filed reports of the Geological Survey, to most published and open-filed reports of the U.S....
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...
Map showing foundation conditions in the Fairbanks D-2 NW Quadrangle, Alaska
Troy L. Pewe, John W. Bell
1975, Miscellaneous Field Studies Map 668-D
In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then...
Map showing construction materials in the Fairbanks D-2 NW Quadrangle, Alaska
Troy L. Pewe, John W. Bell
1975, Miscellaneous Field Studies Map 668-C
This map is based on data presented on the Geologic map of the Fairbanks D-2 quadrangle (Map I-907, Pewe and others, 1975), the Map showing distribution of permafrost in the Fairbanks D-2 quadrangle (Map MF-668A, Pewe and Bell, 1975a), the map showing ground-water conditions in the Fairbanks D-2 quadrangle (Map...
Surface current observations--Beaufort Sea, 1972
Peter Barnes, Richard Garlow
1975, Open-File Report 75-619
Sediment transport via water and ice in the Beaufort Sea off northern Alaska is related to the movement of the surficial waters. As development proceeds along the north slope of alaska, a knowledge of the potential drift trajectories of water, ice, sediment and pollutants will be needed. In an attempt...
Age and tectonic significance of volcanic rocks on St. Matthew Island, Bering Sea, Alaska
William Wallace Patton Jr., Marvin A. Lanphere, Thomas P. Miller, Richard A. Scott
1975, Open-File Report 75-150
Reconnaissance investigations of the heretofore little known volcanic assemblage on St. Matthew Island provide significant information on the tectonic history of the Bering Sea shelf. St. Matthew Island is made up of approximately 500 m of subaerial calc-alkaline volcanic rocks ranging in composition from high-alumina basalt to rhyolite. Four K-Ar...
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...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in Northern Alaska
Edward Huntington Cobb
1975, Open-File Report 75-628
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in 11 quadrangles in northern Alaska. All references to published and open-filed reports of the Geological Survey, to most published and open-filed reports of the U.S....
Gravity map of the Nabesna Quadrangle, Alaska
David F. Barnes, Robert L. Morin
1975, Miscellaneous Field Studies Map 655-I
The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of...
Map showing construction materials in the Fairbanks D-1 SW Quadrangle, Alaska
1975, Miscellaneous Field Studies Map 671-C
This map is based on data presented on the Geologic map of the Fairbanks D-1 SW quadrangle (Map I-949, Pewe and others, in press), the Map showing distribution of permafrost in the Fairbanks D-1 SW quadrangle (Map MF-671A, Pewe and Bell, 1975a), the map showing ground-water conditions in the Fairbanks...
Radiometric dates from Alaska: A 1975 compilation
D. L. Turner, Donald Grybeck, Frederic H. Wilson
1975, Alaska Division of Geological & Geophysical Surveys Special Report DGGS SR 10
The following table of radiometric dates from Alaska includes published material through 1972 as well as some selected later data. The table includes 726 mineral and whole-rock dates determined by the K-Ar, Rb-Sr, fission-track U-Pb, and Pb-alpha techniques.The data are organized in alphabetical order of the 1:250,000 scale quadrangles in...
Radiometric age map of southeast Alaska
Frederic H. Wilson, D. L. Turner
1975, Report
This map includes published, thesis, and open-file radiometric data available to us as of June, 1975. Some dates are not plotted because of inadequate location data in the original references.The map is divided into five sections, based on 1:1,000,000 scale enlargements of the National Atlas maps of Alaska. Within each...
