Aeromagnetic and gravity anomaly maps and a hydrothermal veins favorability map of the Wallace 1 degree by 2 degrees Quadrangle, Montana and Idaho

This map is part of a folio of maps of the Wallace 1° x 2° quadrangle, Montana and Idaho, compiled as part of the Conterminous united States Mineral Assessment Program (CUSMAP).  Background information about this folio is published in U.S. Geological Survey Circular 920.  CUSMAP is designed to systematically assess the mineral resource potential of selected 1° x 2° quadrangles at a scale of 1:250,

Aeromagnetic maps of the Colorado River region including the Kingman, Needles, Salton Sea, and El Centro 1 degree by 2 degrees quadrangles, California, Arizona, and Nevada

Aeromagnetic data for the Colorado river region have been compiled as part of the Pacific to Arizona Crustal Experiment (PACE) Project. The data are presented here in a series of six compilations for the Kingman, Needles, Salton Sea, and El Centro 1 degree by 2 degree quadrangles, California, Arizona, and Nevada, at scales of 1:250,000 and 1:750,000. The scales and map areas are identical to those
