Geochemical maps showing the distribution and abundance of gold in stream sediments and of gold and silver in heavy-mineral concentrates in the Seward and Blying Sound quadrangles, Alaska
R. B. Tripp, W.D. Crim, R. M. O’Leary
1978, Miscellaneous Field Studies Map 880-F
Reconnaissance geochemical and mineralogical sampling was done in the Seward and Blying Sound quadrangles during 1975 and 1976 as part of the Alaska Mineral Resources Assessment Program (AMRAP). These maps show the distribution and abundance of gold and silver in heavy-mineral concentrates. Stream-sediment and heavy-mineral concentrate samples were collected from active...
Maps showing mineralogical data for nonmagnetic heavy-mineral concentrates in the Talkeetna Quadrangle, Alaska
R. B. Tripp, R. C. Karlson, G.C. Curtin
1978, Miscellaneous Field Studies Map 870-I
Reconnaissance geochemical and mineralogical sampling was done in the Talkeetna Quadrangle during 1975 and 1976 as part of the Alaska Mineral Resource Assessment Program (AMRAP). These maps show the distribution of gold, scheelite, chalcopyrite, arsenopyrite, galena, fluorite, cinnabar, and malachite in the nonmagnetic fraction of heavy-mineral concentrates. Heavy-mineral concentrate samples...
Mineralogical map showing the distribution and abundance of gold, scheelite, chalcopyrite, arsenopyrite, minium, and sapphire corundum in heavy-mineral concentrates in the Seward and Blying Sound quadrangles, Alaska
R. B. Tripp, W.D. Crim
1978, Miscellaneous Field Studies Map 880-G
Reconnaissance geochemical and mineralogical sampling was done in the Seward and Blying Sound quadrangles during 1975 and 1976 as part of the Alaska Mineral Resources Assessment Program (AMRAP).

Map showing placer deposits of the Seward and Blying Sound quadrangles, Alaska
Russell G. Tysdal
1978, Miscellaneous Field Studies Map 880-B
Placer gold was first recovered from stream gravels of the Seward quadrangle about 1850 by P.P. Doroshin, a mining engineer employed by the Russian-American Company. He obtained a few ounces of gold from gravels from two streams that flow into the Kenai River below Kenai Lake (Moffit, 1906, p. 8)....
Geochemical and generalized geologic map showing distribution and abundance of barium, arsenic, boron, and vanadium in stream sediments in the Chandalar Quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1978, Miscellaneous Field Studies Map 878-G
This geochemical map shows the distribution and abundance of barium (Ba), arsenic (As), boron (B), and vanadium (V) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is a part of a series of geochemical maps that together with the background information circular (Reiser...
Geochemical and generalized geologic map showing distribution and abundance of molybdenum, copper, and lead in stream sediments in the Chandalar Quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1978, Miscellaneous Field Studies Map 878-D
This geochemical map shows the distribution and abundance of molybdenum (Mo), copper (Cu), and lead (Pb) of -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is a part of a series of geochemical maps that together with the background information circular (Reiser and others,...
Geochemical and generalized geologic map showing distribution and abundance of zinc in stream sediments in the Chandalar Quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1978, Miscellaneous Field Studies Map 878-E
This geochemical map shows the distribution and abundance of zinc in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is a part of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio on the...
