Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: May 1976
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1976, Open-File Report 76-300-E
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Distribution and abundance of copper in stream sediments and moraine debris, McCarthy Quadrangle, Alaska
Keith Robinson, C. M. McDougal, G.W. Day, Theodore Billings
1976, Miscellaneous Field Studies Map 773-F
A geochemical survey was conducted in the McCarthy quadrangle, Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for copper, from 1,454 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological...
Aeromagnetic map of the Tanacross Quadrangle, Alaska
Andrew Griscom
1976, Miscellaneous Field Studies Map 767-A
The aeromagnetic map (sheet 1) of the Tanacross quadrangle was prepared in 1971 and subsequently released by the State of Alaska as an open-file map (Alaska Div. Geology and Geophysics, 1973). The data were collected along north-south traverses spaced at 1.6-km intervals and from an altitude of 300 m above...
Preliminary residual magnetic map of the eastern Bering Shelf and parts of western Alaska
Kimberly A. Bailey, Alan K. Cooper, Michael S. Marlow, David W. Scholl
1976, Miscellaneous Field Studies Map 716
Residual magnetic anomalies for the offshore data were calculated by subtracting the Earth's main dipole field, adjusted for secular variations (based on the International Geomagnetic Reference Field (IGRF), epoch 1965, Fabiano and Peddie, 1969), from the observed values of the surveys listed below. The effects of diurnal variations and magnetic...
Preliminary report on uranium-, thorium-, and rare-earth-bearing rocks near Golovin, Alaska
Thomas P. Miller, Raymond L. Elliott, Warren I. Finch, Robert A. Brooks
1976, Open-File Report 76-710
Uranium-, thorium-, and rare-earth bearing rocks were found by a U.S. Geological Survey field party 15 miles northeast of Golovin, Alaska, in  the southeastern Seward Peninsula (fig. 1) in June 1976. The mineralized areas occur in syenite and appear to be concentrated along the margins of alkaline dikes, with allanite...
Distribution and abundance of arsenic in bedrock, mineralized, vein, and altered rock samples, McCarthy quadrangle, Alaska
Keith Robinson, C. M. McDougal, R.M. O'Leary, Theodore Billings
1976, Miscellaneous Field Studies Map 773-M
A geochemical survey was conducted in the McCarthy quadrangle Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for arsenic from 827 rock samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Tanacross quadrangle, Alaska
Helen Laura Foster, N. R. D. Albert, D.F. Barnes, G.C. Curtin, Andrew Griscom, D.A. Singer, James G. Smith
1976, Circular 734
The Tanacross quadrangle, consisting of 17,400 km 2 (6,700 mi 2) in east-central Alaska, was investigated by an interdisciplinary research team for the purpose of assessing the mineral resource potential of the quadrangle. This report provides the background information for a folio of maps on the geology, geophysics, reconnaissance geochemistry,...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1976
John B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1976, Open-File Report 76-300-B
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Geologic map of the McCarthy Quadrangle, Alaska
E.M. MacKevett Jr.
1976, Miscellaneous Field Studies Map 773-A
Diverse Quaternary surficial deposits are abundant in the quadrangle. Quaternary processes of deposition and erosion strongly influenced the landscape, producing many of the scenic and physiographic features. ...
Mineral deposits and occurrences in the McCarthy Quadrangle, Alaska
E.M. MacKevett Jr.
1976, Miscellaneous Field Studies Map 773-B
The McCarthy quadrangle contains numerous and diverse mineral deposits in various geologic settings. Copper is the dominant mineral commodity, both historically and in terms of potential future production. Gold and silver are the only other metals that have been produced. The metalliferous deposits are concentrated in a northwest-trending belt along...
