Post-Carboniferous stratigraphy, northeastern Alaska
R. L. Detterman, H. N. Reiser, W. P. Brosge, J.T. Dutro Jr.
1975, Professional Paper 886
Post-Carboniferous sedimentary rocks exposed in northeastern Alaska constitute an almost continuous sequence representing all systems from Permian to Quaternary. Because the rocks are well exposed, only slightly deformed, and very fossiliferous, they comprise an important biostratigraphic reference section. Regional and local unconformities are present, and minor hiatuses can be identified...
Paleozoic corals of Alaska
Michael Churkin Jr., W. A. Oliver Jr., C.W. Merriam, A. K. Armstrong, C. L. Rowett
1975, Professional Paper 823-A-D

Gravity map of the Nabesna Quadrangle, Alaska
David F. Barnes, Robert L. Morin
1975, Miscellaneous Field Studies Map 655-I
The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of...
Aeromagnetic map of the Nabesna Quadrangle, Alaska
Andrew Griscom
1975, Miscellaneous Field Studies Map 655-H
The aeromagnetic map (sheet 1) of the Nabesna quadrangle was prepared in 1971 and subsequently released by the State of Alaska as an open-file map (Alaska Div. Geol. and Geophysics, 1973). The data were collected along north-south traverses spaced at 1.6 km intervals at an altitude of 330 m (1000...
Perspective diagrams showing geochemical abundance of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in the Nabesna Quadrangle, Alaska
Sherman P. Marsh
1975, Miscellaneous Field Studies Map 655-G
The seven perspective diagrams on this sheet show the distribution patterns of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in stream sediments in the Nabesna quadrangle. The diagrams portray the distribution and abundance of the elements and their relation to some of the geologic units (Richter, 1975) in easy-to-visualize,...
