Gazetteer of coastal and offshore features of the Bering Sea and Aleutian Arc
Marybeth Gerin
1979, Open-File Report 79-1219
This gazetteer presents the names of seafloor and coastal features of the Bering Sea and Aleutian Arc. It is the second of three gazetteers that cover the offshore and coastal features of Alaska. Alaska was divided into three major regions - the Gulf of Alaska (Gerin and Molnia, 1978), the...
Gazetteer of coastal and offshore features of the Chukchi and Beaufort seas
Marybeth Gerin, Tau Rho Alpha
1979, Open-File Report 79-1563
This gazetteer presents the names of seafloor and coastal features of the Alaskan Arctic Coast. It includes the named features of the Chukchi and Beaufort Seas south of 74°N latitude and the Alaskan coast from the Bering Strait to Demarcation Point. The gazetteer of the Chukchi and Beaufort Seas is...
Catalog of earthquakes in southern Alaska: January-March 1978
C.D. Stephens, J.C. Lahr, K.A. Fogleman, M.A. Allan, S.M. Helton
1979, Open-File Report 79-718
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...
Quaternary stratigraphic sections with radiocarbon dates, Chandalar Quadrangle, Alaska
Thomas D. Hamilton
1979, Open-File Report 79-751
Surficial geologic mapping of the Chandalar quadrangle was carried out during 1975 and 1976 as part of the Arctic Environmental Program of the U.S. Geological Survey. Ten organic samples were collected at that time for radiocarbon dating. Six samples have been dated by Stephen W. Robinson at the U.S. Geological...
Notes on the acquisition of high resolution seismic reflection profiles, side-scanning sonar records, and sediment samples from lower Cook Inlet and Kodiak Shelf, R/V Sea Sounder Cruise S8-78-WG, August 1978
Monty A. Hampton, Arnold H. Bouma
1979, Open-File Report 79-1311
The third U.S. Geological Survey geo-environmental cruise in lower Cook Inlet and on the Kodiak shelf and adjacent continental slope, Gulf of Alaska, was conducted aboard the R/V SEA SOUNDER from 2 August to 22 August, 1978 (Fig. 1, 2, and 3). The objectives of the cruise were to study...
Calc-alkaline plutonism along the Pacific rim of southern Alaska
Travis Hudson
1979, Open-File Report 79-953
Field, petrology, and age data on southern Alaska plutonic rocks now enable the delineation of eight calc-alkaline plutonic belts. These belts of plutons or batholithic complexes are curvilinear to linear and trend parallel or subparallel to the continental margin. The belts represent the principal loci of emplacement for plutons of...
Availability of palynomorph and foraminifera microscope slides from test wells of National Petroleum Reserve in Alaska; group 1
Roger J. Witmer
1979, Open-File Report 80-193
The first group of palynomorph (pollen, spores, dinoflagellates, acritarchs) and Foraminifera microscope slides prepared from test wells drilled during the National Petroleum Reserve in Alaska (N.P.R.A.) program and the earlier Naval Petroleum Reserve No. 4 (N.P.R.-4) program are now being made available for examination. Jurisdiction of N.P.R.-4 was transferred from...
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...
Knik Glacier, Alaska, May 1979 monument and glacier survey
Dennis C. Trabant, L.R. Mayo
1979, Open-File Report 80-48
From 1915, or earlier, to 1966, with the exception of 1963, Knik Glacier annually formed and released Lake George, the largest glacier-dammed lake in Alaska. Eleven geodetically controlled survey stations were defined in the basin, and 22 glacier surface altitudes were measured. This is the first effort in a continuing...
Reconnaissance snow surveys of the National Petroleum Reserve in Alaska, April 1977 and April-May 1978
Charles E. Sloan, Dennis Trabant, William Glude
1979, Open-File Report 79-1342
Reconnaissance snow surveys of the NPRA (National Petroleum Reserve in Alaska) were made in April 1977 and April-May 1978 to ascertain general snow characteristics and distribution patterns. Thirty-nine sites in 1977 and forty-one sites in 1978 were sampled to determine snow depth, density, structure, and snow-soil interface temperature. In addition,...
Mesozoic stratigraphy: the key to tectonic analysis of southern and central Alaska
David Lawrence Jones, Norman J. Silberling
1979, Open-File Report 79-1200
Southern and central Alaska constitutes an enormous tectonic mosaic composed of separate structural blocks and fragments that accreted to North America during Mesozoic and early Cenozoic time. Some of these blocks are far traveled, as shown by paleomagnetic and paleontologic studies. More than 25 discrete tectonostratigraphic terranes now are known,...
Petroleum source potential of rocks dredged from the continental slope in the eastern Gulf of Alaska
George Plafker, George Edwin Claypool
1979, Open-File Report 79-295
A bedrock dredging program by the R/V Sea Sounder in 1977 and 1978 along the continental slope in the eastern Gulf of Alaska revealed a previously unknown Eocene sedimentary sequence that includes argillaceous rocks with favorable petroleum source rock characteristics. Seven of 36 dredge hauls that sampled outcrop contain argillaceous...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Mount Hayes Quadrangle, Alaska
Edward Huntington Cobb
1979, Open-File Report 79-238
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 the Mount Hayes quadrangle, Alaska. References to most reports of the Geological Survey, the U.S. Bureau of Mines, and the State of Alaska Division of...
Observations on the geology and petroleum potential of the Cold Bay-False Pass area, Alaska Peninsula
Hugh James McLean
1979, Open-File Report 79-1605
Upper Jurassic strata in the Black Hills area consist mainly of fossiliferous, tightly cemented, gently folded sandstone deposited in a shallow marine environment. Upper Cretaceous strata on Sanak Island are strongly deformed and show structural features of broken formations similar to those observed in the Franciscan assemblage of California. Rocks...
