Investigations at active volcanoes
Thomas L. Wright
1971, Eos, Transactions, American Geophysical Union (52) 57-62
The field of volcanology has expanded greatly in the years 1967–1970, and work on active volcanoes has kept pace with this expansion. I have restricted this summary and the accompanying bibliography to studies by U.S.‐based investigators of active or potentially active volcanoes. I have been immeasurably aided in writing this...
Quaternary faulting in the eastern Alaska Range
D.H. Richter, N.A. Matson Jr.
1971, Bulletin of the Geological Society of America (82) 1529-1540
Quaternary faulting is well displayed along the Denali fault system and the recently recognized and related Totschunda fault system in the eastern Alaska Range. The principal movement on both fault systems is right-lateral strike-slip. Offset glacial features of Wisconsin age indicate minimum Holocene slip rates of 1.1 to 3.5 cm...
Origin and emplacement of the ultramafic rocks of the Emigrant Gap area, California
O.B. James
1971, Journal of Petrology (12) 523-560
The ultramafic bodies of the Emigrant Gap area are part of a mafic complex within a large composite pluton of the northern Sierra Nevada. The pluton was magmatically emplaced and is surrounded by an aureole of hornblende-hornfels facies rocks. Inclusions of country rock in ultramafic rock are of pyroxene-hornfels...
A Pliocene flora and insect fauna from the Bering Strait region
D.M. Hopkins, J.V. Matthews, J. Wolfe, M.L. Silberman
1971, Palaeogeography, Palaeoclimatology, Palaeoecology (9) 211-231
A flood-plain forest has been preserved beneath a lava flow that invaded the Inmachuk River Valley in the northern part of the Seward Peninsula, Alaska, during the Pliocene Epoch. The fossil flora is of great biogeographic interest because of its position (Fig. 1)...
Lower Devonian graptolites from southeastern Alaska
Michael Churkin Jr., Herman Jaeger, G. Donald Eberlein
1970, Lethaia (3) 183-202
The youngest zones of Monograptus occur in Devonian black shale and slate along the western shore of Prince of Wales Island and on Noyes Island, southeastern Alaska. The following five species of Monograptus, in close association with vascular plants and marine shelly faunas, indicate a Praguian, (Siegenian to Early...
Biostratigraphy and dolomite porosity trends of the Lisburne Group
Augustus K. Armstrong, Bernard L. Mamet
1970, Book chapter, Proceedings of the geological seminar on the North Slope of Alaska, 1970
This preliminary study is based on measured and carefully collected sections of the Lisburne Group (fig. 1, sees. 1-29). The outcrops extend from Cape Lisburne (sec. 1) in the west to Egaksrak River (sec. 29) in northeastern Alaska and are used as the basic building blocks for the carbonate facies...
Buldir Depression - A Late Tertiary graben on the Aleutian Ridge, Alaska
M.S. Marlow, D.W. Scholl, E.C. Buffington, R.E. Boyce, T.R. Alpha, P.J. Smith, C.J. Shipek
1970, Marine Geology (8) 85-108
Buldir Depression is a large, rectilinear basin that lies on the northern edge of the Aleutian Ridge and is aligned with the arcuate chain of active volcanoes on the ridge crest. The depression appears to be a volcanic-tectonic feature, which began to form...
The structure and origin of the large submarine canyons of the Bering Sea
D.W. Scholl, E.C. Buffington, D.M. Hopkins, T.R. Alpha
1970, Marine Geology (8) 187-210
Three exceptionally large and long submarine canyons — Bering, Pribilof, and Zhemchug — incise the continental slope underlying the southeastern Bering Sea. Bering Canyon, the world's longest known slope valley, is approximately 400 km long and has a volume of 4,300 km3. The volume of Pribilof Canyon is 1,300 km3 and...
