Petroleum geology of Kodiak Shelf, Alaska.
Michael A. Fisher
1980, American Association of Petroleum Geologists Bulletin (64) 1140-1157
Organic geochemical data show that Cenozoic rocks on Kodiak Island, in Albatross basin, and under the continental slope generally contain less than 0.5 wt. % organic carbon. Moreover, kerogen from all rocks analyzed is predominantly (60 to 100%) herbaceous; woody and coaly kerogens are present in secondary (20 to 40%)...

Origin of gasoline-range hydrocarbons and their migration by solution in carbon dioxide in Norton basin, Alaska.
Keith A. Kvenvolden, George E. Claypool
1980, American Association of Petroleum Geologists Bulletin (64) 1078-1086
Carbon dioxide from a submarine seep in Norton Sound, Alaska, carries a minor component of gas- and gasoline-range hydrocarbons. The molecular and isotopic compositions of the hydrocarbon gases and the presence of gasoline-range hydrocarbons indicate that these molecules are derived from thermal alteration of marine and/or nonmarine organic matter buried...
Holocene Pacific–North American plate interaction in southern Alaska: Implications for the Yakataga seismic gap
J.C. Lahr, George Plafker
1980, Geology (8) 483-486
The St. Elias, Alaska, earthquake (magnitude 7.1 Ms) on February 28, 1979, occurred along the complex Pacific–North American plate boundary between Yakutat Bay and Prince William Sound, rupturing only a fraction of the seismic gap identified in that region. To aid in evaluating the...

R. Van Der Voo, M. Jones, C. S. Grommé, G.D. Eberlein, M. Churkin Jr.
1980, Journal of Geophysical Research Solid Earth (85) 5281-5296
Paleozoic limestone, graywacke, sandstone, milestone, red beds and volcanic rocks of the Alexander terrane, southeastern Alaska, have yielded six paleomagnetic pole positions after thermal and alternating-field demagnetization. These poles are from sample groups of late Middle Ordovician, Late Ordovician, Devonian, Late Devonian, and early and late Carboniferous age. To test...

1980, Report
This report is a digest of information furnished by Federal agencies conducting sedimentation investigations on work in progress or planned, important findings, new methods, new publications, laboratory and other research activities, and other pertinent information. The material has been organized by major drainage regions in the conterminous United States,Alaska, Hawaii,...
Viral erythrocytic necrosis: Some physiological consequences of infection in chum salmon (Oncorhynchus keta)
John R. MacMillan, Daniel M. Mulcahy, Marsha L. Landolt
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 799-804
Erythroid cells in chum salmon (Oncorhynchus keta) susceptible to infection with erythrocytic necrosis virus (ENV) were examined by light and electron microscopy. Cells of stages II, III, IV, V, and VI contained complete eyrthrocytic necrosis virions in the cytoplasm. Viruses closely resembling ENV were also detected in the nuclei of...
United States Geological Survey Yearbook, fiscal year 1978
Water Resources Division, U.S. Geological Survey
1979, Report
Fiscal year 1978 saw the U.S. Geological Survey continuing to perform its basic historical missions of collecting, analyzing, and disseminating information about the Earth, its processes, and its water and mineral resources. Classifying Federal lands and supervising lessee mineral extraction operations on those lands were also major Survey concerns during...
Environmental aspects of engineering geological mapping in the United States
Dorothy H. Radbruch-Hall
1979, Bulletin of the International Association of Engineering Geology (19) 351-358
Many engineering geological maps at different scales have been prepared for various engineering and environmental purposes in regions of diverse geological conditions in the United States. They include maps of individual geological hazards and maps showing the effect of land development on the environment. An approach to assessing the environmental...
Volcanic ash in surficial sediments of the Kodiak shelf - An indicator of sediment dispersal patterns
M. A. Hampton, A.H. Bouma, T. P. Frost, I.P. Colburn
1979, Marine Geology (29) 347-356
Surficial sediments of the Kodiak shelf, Gulf of Alaska, contain various amounts of volcanic ash whose physical properties indicate that it originated from the 1912 Katmai eruption. The distribution of ash is related to the shelf physiography and represents redistribution by oceanic circulation rather than the original depositional pattern from...
Geology and tectonic development of the continental margin north of Alaska
Arthur Grantz, Stephen Eittreim, David A. Dinter
1979, Tectonophysics (59) 263-291
The continental margin north of Alaska, as interpreted from seismic reflection profiles, is of the Atlantic type and consists of three sectors of contrasting structure and stratigraphy. The Chukchi sector, on the west, is characterized by the deep late Mesozoic and Tertiary North Chukchi basin and the Chukchi Continental Borderland....
CDP seismic sections of the western Beaufort continental margin
Stephen Eittreim, Arthur Grantz
1979, Tectonophysics (59) 251-262
The continental rise, slope, and shelf in the Beaufort Sea off northern Alaska were surveyed with 5600 km of common-depth-point (CDP) seismic data by the U.S. Geological Survey in 1977. The lower continental rise consists of a wedge of at least 4.5 km of low-velocity, generally flat-lying, parallel-bedded sediments. Slump-related...
Clay mineralogy, fine-grained sediment dispersal, and inferred current patterns, lower Cook Inlet and Kodiak shelf, Alaska
James R. Hein, Arnold H. Bouma, Monty A. Hampton, Ross C. Robin
1979, Sedimentary Geology (24) 291-306
Because lower Cook Inlet and Kodiak shelf are being explored and developed for their petroleum resources, it is essential for environmental reasons to understand the sediment dispersal routes and current patterns. The Susitna River flows into upper Cook Inlet and is the source of clay minerals in Holocene deposits found...

Cretaceous sandstones in the Umiat Anticline contain the largest volume of oil discovered to date in the National Petroleum Reserve in Alaska. Umiat test well 11, although dry and abandoned, penetrated the most complete sequence of Cretaceous rocks in the Umiat area. Cretaceous formations cored (oldest to youngest) were the...
Occurrence of uranium in rocks of the intrusive complex at Ekiek Creek, western Alaska
Alan R. Wallace
1979, Open-File Report 79-1653
Uranium in the Ekiek Creek Complex of western Alaska is related to a niobium-rich pyrochlore in the nepheline syenite of the complex. The complex consists of an aegirine-phlogopite pyroxenite that has been intruded and partly replaced by nepheline syenite. The contact zone between the two igneous units varies from a...

1979, Circular 783
The geology, geochemistry, geophysics, and Landsat imagery of the Big Delta quadrangle, 16,335 km 2 in the Yukon-Tanana Upland of east-central Alaska, were investigated, and maps and reports were prepared by an interdisciplinary research team for the purpose of assessing the mineral potential.
