Tectonics of the March 27, 1964, Alaska earthquake
George Plafker
1969, Professional Paper 543-I
The March 27, 1964, earthquake was accomp anied by crustal deformation-including warping, horizontal distortion, and faulting-over probably more than 110,000 square miles of land and sea bottom in south-central Alaska. Regional uplift and subsidence occurred mainly in two nearly parallel elongate zones, together about 600 miles long and as much...
Preliminary carbonate lithofacies maps and possible dolomite porosity trends, Mississippian-Pennsylvanian Lisburne Group, North Slope, Alaska
Augustus K. Armstrong
1969, Open-File Report 69-13
Carbonate porosity within the Mississippian-Pennsylvanian age Lisburne Group is probably extensively developed in the subsurface of the North Slope. The Lisburne Group may prove to be one of the more significant reservoir zones in the region and should not be overlooked in any exploration program. Isopach maps for the total...
Paleogene floras from the Gulf of Alaska
Jack A. Wolfe
1969, Open-File Report 69-323
Numerous collections of fossil plants from the Gulf of Alaska region were obtained from rocks that are well dated by marine mollusks. The mollusks indicate that the oldest possible age for the lowest plant assemblage is middle Eocene (Domengine) and that the youngest possible age for the highest Paleogene plant...
Erosion and deposition on a beach raised by the 1964 earthquake Montague Island, Alaska
M. J. Kirkby, Anne V. Kirkby
1969, Professional Paper 543-H
During the 1964 Alaska earthquake, tectonic deformation uplifted the southern end of Montague Island as much as 33 feet or more. The uplifted shoreline is rapidly being modified by subaerial and marine processes. The new raised beach is formed in bedrock, sand, gravel, and deltaic bay-head deposits, and the effect...
Bathymetry and isopach map of stratified Holocene sediments of Nuka Bay, Alaska
Erk Reimnitz, Roland E. von Huene
1969, Open-File Report 69-219
The bathymetric chart of the Nuka Bay area, Alaska, is based on U.S.C.&G.S. Chart 8530, and over 750 km of additional sounding lines made in 1965 and in 1968. Continuous reflection seismic records made along the same tracks as the bathymetric profiles served as the basis for the Isopach map....
Distribution of oxygen and carbon isotopes in fossils of late cretaceous age, western interior region of North America
H. A. Tourtelot, R.O. Rye
1969, Geological Society of America Bulletin (80) 1903-1922
The oxygen isotope composition of both calcite and aragonite of the pelecypod Inoceramus is lighter than the composition of the aragonite of associated baculites and other cephalopods from the western interior region, the Gulf and Atlantic Coastal Plains, parts of Canada, and West Greenland. This difference cannot be explained by...
Progress on a gravity map of Alaska
David F. Barnes
1969, Eos Science News (50) 550-552
The U.S. Geological Survey began gravity surveys in Alaska ten years ago with local surveys in the Copper River and Tanana Basins. Shortly before the 1963 AGU gravity symposium [Barnes, 1965], the emphasis shifted from local surveys to the preparation of a reconnaissance gravity map of the whole state with...
The structure and tectonic history of the eastern Aleutian Trench
Roland E. von Huene, George G. Shor Jr.
1969, Geological Society of America Bulletin (80) 1889-1902
The tectonic character of the eastern Aleutian Trench and some major events in its geologic history can be estimated from nine continuous seismic reflection records. A section of pre-trench, deep oceanic sediments rests on the down-warped crust that forms the trench. Nearly horizontal undeformed strata that unconformably overlie this deep...
