Maps

Fundamental Science Practices

USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.

Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Composite geochemical map of anomalous copper and molybdenum distribution in the Tanacross Quadrangle, Alaska Composite geochemical map of anomalous copper and molybdenum distribution in the Tanacross Quadrangle, Alaska

This geochemical map delineates drainage basins in which either anomalous copper, molybdenum, or both copper and molybdenum 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...

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...
