Distribution and abundance of gold in stream sediments and moraine debris, McCarthy quadrangle, Alaska Distribution and abundance of gold in stream sediments and moraine debris, McCarthy quadrangle, Alaska
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 gold from 764 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976 using...
Distribution and abundance of lead in stream sediments and moraine debris, McCarthy Quadrangle, Alaska Distribution and abundance of lead in stream sediments and moraine debris, McCarthy Quadrangle, Alaska
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 lead, from 1,453 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976 using
Distribution and abundance of molybdenum in bedrock, mineralized, vein and altered rock samples, McCarthy quadrangle, Alaska Distribution and abundance of molybdenum in bedrock, mineralized, vein and altered rock samples, McCarthy quadrangle, Alaska
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 using semi-quantitative emission...
Geochemical maps showing the distribution and abundance of arsenic and mercury in the Tanacross Quadrangle, Alaska Geochemical maps showing the distribution and abundance of arsenic and mercury in the Tanacross Quadrangle, Alaska
This series of geochemical maps shows the distribution of arsenic and mercury in the minus-80-mesh stream sediment and of arsenic in the ash of streambank sod (mixed organic and inorganic material) collected beneath the water level. The geochemical data are plotted on a base map that shows generalized geology and the drainage pattern. The map symbols show the sample sites and ranges of...
Geochemical maps showing the distribution and abundance of beryllium in the Tanacross Quadrangle, Alaska Geochemical maps showing the distribution and abundance of beryllium in the Tanacross Quadrangle, Alaska
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 geology and the drainage pattern. The map symbols show the...
Geochemical maps showing the distribution and abundance of copper in the Tanacross Quadrangle, Alaska Geochemical maps showing the distribution and abundance of copper in the Tanacross Quadrangle, Alaska
This series of geochemical maps shows the distribution of copper 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 aquatic bryophytes (mosses). The copper data are plotted...

Geochemical maps showing the distribution and abundance of tin in the Tanacross Quadrangle, Alaska Geochemical maps showing the distribution and abundance of tin in the Tanacross Quadrangle, Alaska
This series of geochemical maps shows the distribution of tin 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 geology and the drainage pattern. The map symbols show the sample...
