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...

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...
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...
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...

During Late Cretaceous time a broad north-trending epicontinental sea covered much of the western interior of North America and extended from the Gulf of Mexico to the Arctic Ocean. The sea was bounded on the west by a narrow, unstable, and constantly rising cordillera which extended from Central America to...
