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

Geochemical and generalized geologic map showing distribution and abundance of antimony and niobium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska Geochemical and generalized geologic map showing distribution and abundance of antimony and niobium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska
This geochemical map shows the distribution and abundance of antimony (Sb) and niobium (Nb) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is one of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio on the Chandalar quadrangle, Alaska. The data are plotted on...
Geochemical and generalized geologic map showing distribution and abundance of nickel, cobalt, lanthanum and yttrium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska Geochemical and generalized geologic map showing distribution and abundance of nickel, cobalt, lanthanum and yttrium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska
This geochemical map shows the distribution and abundance of nickel (Ni), cobalt (Co), lanthanum (La), and yttrium (Y) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is a part of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio on the Chandalar quadrangle...
Geologic and hydrologic aspects of tunneling in the Twin Cities area, Minnesota Geologic and hydrologic aspects of tunneling in the Twin Cities area, Minnesota
This report presents the results of a pilot study of geologic and hydrologic aspects of tunneling in part of the Minneapolis-St. Paul (Twin Cities) metropolitan area, Minnesota. The Minnesota Geological Survey collected, compiled and interpreted geologic and engineering-test data and the U.S. Geological Survey complies and interpreted hydrologic data. The report was prepared on behalf of...
