Geologic studies in Alaska by the U.S. Geological Survey, 1992
Cynthia Dusel-Bacon, Alison B. Till, editor(s)
1993, Bulletin 2068
This collection of 19 papers continues the annual series of U.S. Geological Survey reports on the geology of Alaska. The contributions, which include full-length Articles and shorter Geologic Notes, cover a broad range of topics including dune formation, stratigraphy, paleontology, isotopic dating, mineral resources, and tectonics. Articles, grouped under four...
Distribution, facies, ages, and proposed tectonic associations of regionally metamorphosed rocks in east- and south-central Alaska
Cynthia Dusel-Bacon, Bela Csejtey Jr., Helen L. Foster, Elizabeth O. Doyle, Warren J. Nokleberg, George Plafker
1993, Professional Paper 1497-C
Most of the exposed bedrock in east- and south-central Alaska has been regionally metamorphosed and deformed during Mesozoic and early Cenozoic time. All the regionally metamorphosed rocks are assigned to metamorphic-facies units on the basis of their temperature and pressure conditions and metamorphic age. North of the McKinley and Denali...
Catalog of earthquake hypocenters at Redoubt Volcano and Mt. Spurr, Alaska: October 12, 1989 - December 31, 1990
John A. Power, Gail D. March, John C. Lahr, Arthur D. Jolly, Gina R. Cruse
1993, Open-File Report 93-685-A
The Alaska Volcano Observatory (AVO), a cooperative program of the U.S. Geological Survey, the Geophysical Institute of the University of Alaska, Fairbanks, and the Alaska Division of Geological and Geophysical Surveys, began a program of seismic monitoring at potentially active volcanoes in the Cook Inlet region in 1988. Seismic monitoring...
Levels of lakes in the north Kenai area, Alaska 1970 to 1992
B. J. Bailey, J. A. McIntire
1993, Open-File Report 93-644
The water-surface elevations of 12 lakes near Kenai and Nikiski, Alaska, were measured periodically from 1970 through 1992 using differential leveling techniques. The study was done in cooperation with the Alaska Department of Natural Resources, to help determine seasonal and long-term changes in water storage. Hydrographs accompanied by tables show...
Petroleum exploration plays and resource estimates, 1989, onshore United States; Region 1, Alaska; Region 2, Pacific Coast
Richard B. Powers, editor(s)
1993, Bulletin 2034-A
This study provides brief discussions of the petroleum geology, play descriptions, and resource estimates of 220 individually assessed exploration plays in all 80 onshore geologic provinces within nine assessment regions of the continental United States in 1989; these 80 onshore provinces were assessed in connection with the determination of the...
