Maps showing mineralogical and geochemical data for heavy-mineral concentrates in the Tanacross quadrangle, Alaska
R. B. Tripp, G.C. Curtin, G.W. Day, R. C. Karlson, S.P. Marsh
1976, Miscellaneous Field Studies Map 767-O
This series of maps showing the following data for heavy mineral concentrates: distribution and abundance of selected ore-related minerals, distribution and abundance of copper in the magnetic fraction, and distribution and abundance of lead, copper, tin, beryllium, tungsten and bismuth in the nonmagnetic fraction. The data are plotted on base...
Geochemical maps showing the distribution and abundance of zinc in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-I
This series of geochemical maps shows the distribution of zinc in four sample media: (A) the oxide residue (oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh steam sediment, (C) the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level, and (D) the ash of...
Geochemical maps showing the distribution and abundance of molybdenum in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R.B. Carten, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-G
This series of geochemical maps shows the distribution of molybdenum in four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level, and (D) the ash of...
Geochemical maps showing the distribution and abundance of lead in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, R. M. O’Leary, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-H
This series of geochemical maps shows the distribution of lead in four sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, (C) the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level, and (D) the ash...
Geochemical maps showing the distribution and abundance of beryllium in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-L
This series of geochemical maps shows the distribution of beryllium in three sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, and (C) the ash of aquatic bryophytes (mosses). The geochemical data are plotted on a base map that shows generalized...
Distribution and abundance of molybdenum in bedrock, mineralized, vein and altered rock samples, McCarthy quadrangle, Alaska
Keith Robinson, C. M. McDougal, S.K. McDanal, Theodore Billings
1976, Miscellaneous Field Studies Map 773-J
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 molybdenum from 825 rock samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976...
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...
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...
