Composite geochemical map of anomalous lead and zinc distribution in the Tanacross Quadrangle, Alaska Composite geochemical map of anomalous lead and zinc distribution in the Tanacross Quadrangle, Alaska

This geochemical map shows drainage basins in which either anomalous lead, zinc, or both lead and zinc values were detected in at least one of 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...

Distribution and abundance of arsenic and mercury in stream sediments and moraine debris, McCarthy quadrangle, Alaska Distribution and abundance of arsenic and mercury 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 arsenic and mercury from 426 and 424 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between...

Distribution and abundance of arsenic in bedrock, mineralized, vein, and altered rock samples, McCarthy quadrangle, Alaska Distribution and abundance of arsenic 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 arsenic from 827 rock samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976 using semiquantitative emission...

Distribution and abundance of copper in stream sediments and moraine debris, McCarthy Quadrangle, Alaska Distribution and abundance of copper 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 copper, from 1,454 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976...
