Geochemical maps showing the distribution and abundance of lead in the Tanacross Quadrangle, Alaska Geochemical maps showing the distribution and abundance of lead in the Tanacross Quadrangle, Alaska
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 of aquatic bryophytes (mosses). The geochemical data are...

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...
Geochemical maps showing the distribution and abundance of zinc in the Tanacross Quadrangle, Alaska Geochemical maps showing the distribution and abundance of zinc in the Tanacross Quadrangle, Alaska
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 aquatic bryophytes (mosses). The map symbols show sample sites...
