David A. Brew
1974, Circular 695
The environmental impact analysis made as required by the National Environmental Policy Act of 1969 for the proposed trans-Alaska pipeline included consideration of the (1) technologically complex and geographically extensive proposed project, (2) extremely different physical environments across Alaska along the proposed route and elsewhere in Alaska and in Canada...

Reconnaissance engineering geology of Sitka and vicinity, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Lynn A. Yehle
1974, Open-File Report 74-53
A program to study the engineering geology of most of the larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about Sitka and vicinity is a product of that program. Field-study methods were of a reconnaissance nature,...

Geological Survey open-file reports of Alaska indexed by quadrangle
Edward Huntington Cobb
1974, Open-File Report 74-7
The Geological Survey places in open files reports and maps that are preliminary or ephemeral in nature, are of interest to a small audience only, or consist of masses of essentially raw data. These reports and maps are available to the public and may be consulted at various Geological Survey...
Ultramafic rocks of the Eagle quadrangle, east-central Alaska
Helen L. Foster, Terry E.C. Keith
1974, Journal of Research of the U.S. Geological Survey (2) 657-669
More than 97 separate occurrences of ultramafic rocks, some of which are included in a north west-trending zone of alpine-type ultramafic rocks, have been mapped in the Eagle quadrangle, east-central Alaska. They are divided into three groups primarily on the basis of degree of serpentinization. Group I consists of lens-shaped bodies...
Offset plutons and history of movement along the McKinley segment of the Denali Fault system, Alaska
Bruce L. Reed, Marvin A. Lanphere
1974, GSA Bulletin (85) 1883-1892
The Foraker and McGonagall plutons, bodies of granodiorite with nearly identical mineralogy and chemistry, are considered to be parts of a single igneous mass that has undergone right-lateral displacement of about 38 km along the McKinley segment of the Denali fault system since the igneous mass crystallized about 38 m.y....
Sea otters: Their role in structuring nearshore communities
J. A. Estes, J. F. Palmisano
1974, Science (185) 1058-1060
A comparison of western Aleutian Islands with and without sea otter populations shows that this species is important in determining littoral and sublittoral community structure. Sea otters control herbivorous invertebrate populations. Removal of sea otters causes increased herbivory and ultimately results in the destruction of macrophyte associations. The observations suggest...
Chemical variations across the Alaska-Aleutian Range batholith
Bruce L. Reed, Marvin A. Lanphere
1974, Journal of Research of the U.S. Geological Survey (2) 343-352
A study of 79 chemical analyses of plutonic rocks in the northern part of the Alaska-Aleutian Range batholith shows that K2O and SiO2 in Late Cretaceous and Tertiary rocks decrease toward the Pacific margin and that Al2O3 and CaO increase. Plots for Fe2O3, FeO, MgO, and TiO2 suggest a...
The Border Ranges Fault in south-central Alaska
E. M. MacKevett, George Plafker
1974, Journal of Research of the U.S. Geological Survey (2) 323-329
The Border Ranges fault, a major fault of southern Alaska, can be traced for more than 1,000 km arcuately eastward from Kodiak Island to the St. Elias Mountains. Throughout its extent, the fault juxtaposes upper Paleozoic and lower Mesozoic rocks on the north against upper Mesozoic and Tertiary rocks. This...

A prototype global volcano surveillance system monitoring seismic activity and tilt
E.T. Endo, P.L. Ward, D.H. Harlow, R. V. Allen, J. P. Eaton
1974, Bulletin Volcanologique (38) 315-344
The Earth Resources Technology Satellite makes it feasible for the first time to monitor the level of activity at widely separated volcanoes and to relay these data almost instantancously to one central office. This capability opens a new era in volcanology where the hundreds of normally...
Garnet-clinopyroxenite from the Red Mountain pluton, Alaska
R. B. Forbes, R. C. Swainbank
1974, GSA Bulletin (85) 285-292
Several lens-shaped and irregular masses of garnet-clinopyroxenite occur along the north margin of the Red Mountain pluton, near Seldovia, Alaska. The pluton is composed of intercalated dunite, clinopyroxenite, and banded chromite layers. The chromite layers appear to dip toward the center of the mass, but they have been deformed, and...

Hydraulic tests in hole UAe-2, Amchitka Island, Alaska
Wilbur C. Ballance
1973, Report
Inflatable straddle packers were used to isolate and test 19 intervals ranging from 56 to 747 meters (183 to 2,450 feet) each in hole UAe-2, Amchitka Island, Alaska. Packer seats were poor in part of the hole because of unstable wall conditions. Thus, some zones had to be tested several...
Probable rift origin of Canada Basin, Arctic Ocean
Irvin L. Tailleur
1973, Book chapter, Arctic geology: proceedings of the Second International Symposium on Arctic Geology (AAPG Memoir 19)
Formation of the Canada basin by post-Triassic rifting seems the most workable and logical hypothesis on the basis of available information. Speculated counterclockwise rotation of the Alaska-Chukchi continental edge best rationalizes the complex geology of northern Alaska, whereas the assumption that a single continental block was present before the Jurassic...
Revised age and structural interpretations of Nuka Formation at Nuka Ridge, northwestern Alaska: Geologic notes
I.L. Tailleur, B. L. Mamet, J.T. Dutro Jr.
1973, American Association of Petroleum Geologists Bulletin (57) 1348-1352
New collections of foraminifers and macrofossils from Nuka Ridge, the type area of the enigmatic Nuka Formation, demonstrate that the type Nuka Formation is not a continuous stratigraphic sequence as originally described. Paleontologic evidence indicates the presence of a structurally repeated sequence at Nuka Ridge consisting of Upper Mississippian (Meramec...
Recurrence of seismic migrations along the central California segment of the San Andreas fault system
M.D. Wood, S.S. Allen
1973, Nature (244) 213-215
VERIFICATIONS of tectonic concepts1 concerning seafloor spreading are emerging in a manner that has direct bearing on earthquake prediction. Although the gross pattern of worldwide seismicity contributed to the formulation of the plate tectonic hypothesis, it is the space-time characteristics of this seismicity that may contribute more...
Sea level history in Beringia during the past 250,000 years
D.M. Hopkins
1973, Quaternary Research (3) 520-540
This paper attempts to relate current knowledge of sea-level history in Beringia to the Broecker-van Donk “Termination” concept of climatic and sea-level history. The Einahnuhtan transgression is thought to represent Termination III, which according to Broecker and van Donk, took place about 225,000...
