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...
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...
Standardization of gravimeter calibrations in the geological survey
David F. Barnes, Howard W. Oliver, Stephen L. Robbins
1969, Eos Science News (50) 526-527
The calibration of gravimeters has long been primarily the concern of geodesists involved in measuring large gravity differences, but recent developments suggest that the precision and stability of gravimeter calibrations may have greater geologic importance in the future. First, the use of high-speed computers and an increasing variety of supplemental...
