Map showing paleocurrent and clast-size data from the Devonian-Mississippian Endicott Group, northern Alaska
T.J. Donovan, I.L. Tailleur
1975, Miscellaneous Field Studies Map 692
The Devonian-Mississippian Endicott Group (Tailleur and others, 1967) is an important geologic unit in the Brooks Range of northern Alaska. It reflects a major tectonic event in the middle and late Paleozoic history of the North American Cordillera. Tailleur and Brosge (1970) interpreted the Endicott as a clastic wedge derived...

Radiometric age map of northern Alaska
Frederic H. Wilson, D. L. Turner
1975, Alaska Division of Geological & Geophysical Surveys Open File Report DGGS AOF 86
This map includes published, thesis, and open-file radiometric data available to us as of June, 1975. Some dates are not plotted because of inadequate location data in the original references.The map is divided into five sections, based on 1:1,000,000 scale enlargements of the National Atlas maps of Alaska. Within each...
Radiometric dates from Alaska: A 1975 compilation
D. L. Turner, Donald Grybeck, Frederic H. Wilson
1975, Alaska Division of Geological & Geophysical Surveys Special Report DGGS SR 10
The following table of radiometric dates from Alaska includes published material through 1972 as well as some selected later data. The table includes 726 mineral and whole-rock dates determined by the K-Ar, Rb-Sr, fission-track U-Pb, and Pb-alpha techniques.The data are organized in alphabetical order of the 1:250,000 scale quadrangles in...

Crustal movement investigations
James C. Savage
1975, Reviews of Geophysics (13) 263-265
Studies of horizontal crustal movement using conventional geodetic methods have been considerably expanded in the quadrennium 1971–1974. The basic fault monitor Geodimeter network now covers most of the major faults in California as well as the zone of faulting that extends into Nevada. Isolated Geodimeter networks in seismic areas of...
Progressive metamorphism of schists recovered from a deep drill hole near Fairbanks, Alaska
Robert B. Forbes, Florence R. Weber
1975, Journal of Research of the U.S. Geological Survey (3) 647-657
In 1965, a deep test hole drilled near Eielson Air Force Base, Fairbanks district, Alaska, penetrated 9,774 ft (2,979.1 m) into schists of the metamorphic complex of the Yukon-Tanana Upland. Cores recovered from the test hole show that the section is dominated by calc-magnesian rocks with subordinate pelitic schists. Pelitic...
