Hydrologic reconnaissance of the eastern North Slope, Alaska, 1975
Joseph M. Childers, C. E. Sloan, J.P. Meckel, J. W. Nauman
1977, Open-File Report 77-492
The part of the Arctic coast of Alaska between the Colville River and the Canadian boundary was visited in April, August, and November 1975. The study area is characterized by its cold climate and is largely uninhabited, but oil and gas discoveries have spurred development of parts of the area....
Bathymetric and shoreline changes, northwestern Prudhoe Bay, Alaska
Peter W. Barnes, Erk Reimnitz, Greg Smith, John Melchior
1977, Open-File Report 77-161
The coastal environment in the vicinity of Prudhoe Bay, Alaska (Fig. 1) is presently being vigorously utilized by petroleum activities. In particular, barges moving freight onshore over the past 8 years, have used the Prudhoe Bay entrance channel almost exclusively. To further facilitate the offloading of supply barges, Atlantic Richfield...
Geologic framework of lower Cook Inlet, Alaska
Michael A. Fisher, Leslie B. Magoon
1977, Open-File Report 77-136
Lower Cook Inlet is located in south-central Alaska between lat 58°45' and 60°30' N. and between long 151° and 154° W. (fig. 1). Geographic features on the perimeter of the area are the Aleutian Range on the northwest, Kalgin Island on the northeast, the Kenai Peninsula on the east, the...
Bibliography of reports by members of the U.S. Geological Survey on the water resources of Alaska: 1870 through 1976
Alvin John Feulner, Katherine M. Reed
1977, Open-File Report 77-687
This bibliography lists publications prepared by members of the U.S. Geological Survey and published either by the Survey or by the other agencies and organizations between 1870 and the end of December 1976. The titles included are those whose primary topic is hydrology, water resources, or other aspects of water...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Tanana Quadrangle, Alaska
Edward Huntington Cobb
1977, Open-File Report 77-432
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 Tanana quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Eagle Quadrangle, Alaska
Edward Huntington Cobb
1977, Open-File Report 77-845
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 Eagle quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports...
The Triassic Chitistone Limestone, Wrangell Mountains, Alaska: stressing detailed descriptions of sabkha facies and other rocks in lower parts of the Chitistone and their relations to Kennecott-type copper deposits
Augustus K. Armstrong, E. M. MacKevett
1977, Open-File Report 77-217
Recent investigations show that sabkha deposits were important in the genesis of Kennecott-type copper ore. Massive chalcocite-rich lodes at Kennecott and nearby deposits formed in the lower 110 meters of the Upper Triassic Chitistone Limestone. The Chitistone and superimposed Upper Triassic and Jurassic sedimentary rocks formed in a marine basin...
Selected Geological Survey, U.S. Bureau of Mines, and Alaska Division of Geological and Geophysical Surveys reports and maps on Alaska released during 1976, indexed by quadrangle
Edward Huntington Cobb
1977, Open-File Report 77-177
This open-file report lists all Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys reports and maps on the geology, geophysics, and mineral and water resources of Alaska published or released to open files in 1976. They are listed by the quadrangles (scale...
Epithermal beryllium deposits in water-laid tuff, western Utah
David A. Lindsey
1977, Economic Geology (72) 219-232
Epithermal beryllium deposits in western Utah have distinctive geological and geochemical associations that provide guides to exploration for new resources of beryllium and associated metals. Beryllium deposits at Spor Mountain and the Honeycomb Hills are uniquely associated with topaz-bearing rhyolite of Late Tertiary age and are restricted to porous water-laid...
Spectacular mobility of ash flows around Aniakchak and Fisher calderas, Alaska
T. P. Miller, R.L. Smith
1977, Geology (5) 173-176
Ash flows around Aniakchak and Fisher calderas in the Aleutian volcanic arc show evidence of having flowed over formidable topographic barriers at distances of tens of kilometres from their source. Ash flows swept down glaciated valleys on the south side of Aniakchak caldera, crossed a broad lowland with an altitude...
Submarine seepage of natural gas in Norton Sound, Alaska
J.D. Cline, M.L. Holmes
1977, Science (198) 1149-1153
Unusual concentrations of dissolved two- to four-carbon alkanes were observed in the waters in Norton Sound in a localized area approximately 40 kilometers south of Nome, Alaska, in 1976. The hydrocarbons were identified in the near-bottom waters downcurrent for more than 100 kilometers from a sea-floor point source. Preliminary dynamic...
Tertiary and Quaternary deposits at The Palisades, central Alaska
Warren E. Yeend
1977, Journal of Research of the U.S. Geological Survey (5) 747-752
The Palisades of the Yukon River, located near the geographic center of Alaska, has long been an attraction to people traveling along the river. Numerous scientific field parties have viewed or visited the locality and published short accounts of their observations. The river bluffs are as much as 90 meters...
Spherulitic rhyolite dike from Goat Island, southeastern Alaska
Walter R. Vennum, G. Donald Eberlein
1977, Journal of Research of the U.S. Geological Survey (5) 445-451
Spherulites, as much as 4 mm in diameter, locally constitute almost 50 percent by volume of a dark-red rhyolite dike that intrudes porphyritic pyroxene gabbro along the northeast coast of Goat Island, 3.2 km northwest of Hydaburg, southeastern Alaska. The largest spherulites are composed mainly of o-quartz, whereas the smallest...
Benthic invertebrates in an arctic mountain stream, Brooks Range, Alaska
K. V. Slack, J. W. Nauman, L. J. Tilley
1977, Journal of Research of the U.S. Geological Survey (5) 519-527
 A 1-day, late-summer reconnaissance of the Dietrich River, Alaska, determined species composition and diversity of benthic invertebrates and examined the correlation between stream order and invertebrate distribution. Benthic invertebrates were collected by dip net, drift net, and 10-rock collections, and results were combined for each station. Forty-nine taxa were identified...
