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...
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). These maps show the distribution and abundance of gold, scheelite, chalcopyrite, arsenopyrite, minium and sapphire corundum in heavy-mineral concentrates. Heavy-mineral concentrate samples were...
Map showing anomalous lead distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles, exclusive of the Black Range Primitive Area, Sierra and Grant counties, New Mexico
K. C. Watts, H. V. Alminas, J. M. Nishi, W.C. Crim
1978, Miscellaneous Field Studies Map 900-J
This map shows the distribution of anomalous lead in the two sample fractions, magnetic (M-1) and nonmagnetic (NM-1) plotted on a base which includes sample localities, topography, and generalized geology modified from Hedlund (1975a, b). It is part of a series of maps for several metals that accompany this folio....
Map showing anomalous tungsten and gold distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles exclusive of the Black Range Primitive Area, Sierra and Grant Counties, New Mexico
K. C. Watts, H. V. Alminas, J. M. Nishi, W.C. Crim
1978, Miscellaneous Field Studies Map 900-I
This map shows the distribution of anomalous tungsten in the two sample fractions, magnetic (M-1) and nonmagnetic (NM-1) gold in the nonmagnetic (NM-1) fraction; these are plotted on a base which includes sample localities, topography, and generalized geology modified from Hedlund (1975a, b). It is part of a series of...
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...
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)....
Mines, prospects, and occurrences map of the Seward and Blying Sound quadrangles, Alaska
Russell G. Tysdal
1978, Miscellaneous Field Studies Map 880-A
The Prince William Sound region may be considered as made up of two extensive and distinctive mineral belts defined by the preponderance of either gold or copper deposits (Capps and Johnson, 1915). In the Seward and Blying Sound quadrangles, the division of the two belts is approximately along the Contact...
