Surficial geologic map of the Meeker 30' x 60' quadrangle, Garfield, Moffat, Rio Blanco and Routt Counties, Colorado

This map is one of a series of four 30' x 60' surficial geologic maps (1:100,000 scale) intended to provide basic geologic information for planning for energy resource development and growth in northwestern Colorado. An effort is made to characterize all surficial materials, regardless of origin. Hence, residuum is given much more emphasis than is customary, and this results in several departures

Vertical surface displacements along a part of the Newport-Inglewood zone of folds and faults, Los Angeles and Orange counties, California

During the past half century, the onshore section of the Newport- Inglewood zone of folds and faults between the Dominguez oil field and Corona del Mar (fig. 1) has been repeatedly leveled to geodetic standards. These essentially fortuitous surveys are unrelated to either the tectonic framework or the urbanization of the Los Angeles basin, but were established instead because the Newport-Inglewoo

Geologic map of the Yellow Hills West Quadrangle, Washoe County, Nevada

This 1988 geologic map of the Yellow Hills West quadrangle, Washoe County, Nevada was produced through mapping work conducted in 1985 and 1986.

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
