Explanation to accompany reconnaissance geologic map of the De Long Mountains A3, B3, and parts of A4, B4 quadrangles, Alaska
Charles F. Mayfield, S.M. Curtis, Inyo Ellersieck, I.L. Tailleur
1983, Open-File Report 83-183
This map is one of a series of three reconnaissance geologic maps of the southern De Long Mountains quadrangle (fig. 1). Because the geology in the three map areas is similar, a composite map explanation has been designed to facilitate their combined use and give a better perspective of the...
The Alaska Mineral Resource Assessment Program: Guide to information contained in folio of geologic and mineral resource maps of the Philip Smith Mountains quadrangle, Alaska
H. N. Reiser, W. P. Brosge, T. D. Hamilton, D.A. Singer, W. D. Menzie II, K. J. Bird, J. W. Cady, J. R. Le Compte, J. B. Cathrall
1983, Circular 759
The geology and mineral resources of the Philip Smith Mountains quadrangle were virtually unexplored until the investigations for oil began in northern Alaska. Construction of the Trans-Alaskan Pipeline System has now made the quadrangle accessible by road. In 1975 and 1976 a team of geologists, geochemists, and geophysicists investigated the...
The Alaska Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Ambler River quadrangle, Alaska
Charles F. Mayfield, I.L. Tailleur, N. R. Albert, Inyo Ellersieck, Donald Grybeck, S. W. Hackett
1983, Circular 793
The Ambler River quadrangle, consisting of 14,290 km2 (5,520 mi2) in northwest Alaska, was investigated by an interdisciplinary research team for the purpose of assessing the mineral resource potential of the quadrangle. This report provides background information for a folio of maps on the geology, reconnaissance geochemistry, aeromagnetics, Landsat imagery,...
Sediment transport in the Tanana River near Fairbanks, Alaska, 1982
P.E. Harrold, R.L. Burrows
1983, Water-Resources Investigations Report 83-4213
Suspended-sediment and bedload-transport rates for the Tanana River near Fairbanks can be related to water discharge, and annual sediment loads can be computed using these relations. For a site at Fairbanks the annual loads in 1982 were 26.1 million metric tons of suspended sediment and 227,000 metric tons of bedload....
Reconnaissance of surface-water resources in the Togiak River basin, southwestern Alaska, 1980 and 1982
D.R. Kernodle, R.R. Squires, J.M. Childers
1983, Water-Resources Investigations Report 83-4170
Data collected during August and September 1980 and March 1982 describe hydrologic characteristics of the Togiak River and its tributaries. Surface waters are generally cold and clear, have significant wilderness recreation values, and provide outstanding salmon habitat. Late summer unit runoff ranged from 2.3 to 8.1 cubic feet per second...
Geochronology, geochemistry, and tectonic environment of porphyry mineralization in the central Alaska Peninsula
Frederic H. Wilson, Dennis P. Cox
1983, Open-File Report 83-783
Porphyry type sulfide systems on the central Alaska Peninsula occupy a transition zone between the Aleutian island magmatic arc and the continental magmatic arc of southern Alaska. Mineralization occurs associated with early and late Tertiary magmatic centers emplaced through a thick section of Mesozoic continental margin clastic sedimentary rocks. The...
