Map showing thermal-alteration indicies in roadless areas and the Santa Lucia Wilderness in the Los Padres National Forest, Southwestern California Map showing thermal-alteration indicies in roadless areas and the Santa Lucia Wilderness in the Los Padres National Forest, Southwestern California
This map shows thermal-alteration indices (TAI's), based on colors of pollen grains, of 115 outcrop and 20 conventional core samples from Mesozoic and lower Tertiary rocks in the southern Coast and western Transverse Ranges, Southwestern California. The TAI's have been calibrated against previously determined vitrinite reflectance values from some of the same sample localities. South of...
Map showing upper Cenozoic rocks and deposits and Quaternary faults, Rio Grande rift, south-central Colorado Map showing upper Cenozoic rocks and deposits and Quaternary faults, Rio Grande rift, south-central Colorado
This map shows the faults and faulted rocks and deposits in the tectonically active part of the Rio Grande rift in Colorado, with particular emphasis on faults and deposits of Quaternary age. The Rio Grande rift in Colorado has been the subject of considerable recent geologic investigation. General compilations of the late Cenozoic tectonic features of the state of Colorado have been...
Maps showing abundance and distribution of mercury in rock samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California Maps showing abundance and distribution of mercury in rock samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California
This map presents data on the abundance and distribution of mercury in 3,146 rock samples from the Medford quadrangle. Most of the rock samples were collected incidental to geologic, geochemical, and mineral resources studies in the period from 1974 to 1980, but about 6 percent date from earlier investigations (Wells, 1940; 1956; Wells and others 1949).
Maps showing anomaly patterns for silver, molybdenum, lead, and zinc in altered rocks and soils, Williams Fork and St. Louis Peak Roadless Areas, Clear Creek, Grand, and Summit counties, Colorado Maps showing anomaly patterns for silver, molybdenum, lead, and zinc in altered rocks and soils, Williams Fork and St. Louis Peak Roadless Areas, Clear Creek, Grand, and Summit counties, Colorado
The U.S. Geological Survey and the U.S Bureau of Mines conducted field studies from 1979 through 1982 to assess the mineral resource potential of the Williams Fork and St. Louis Peak Roadless Areas and the Vasquez Peak Wilderness Study Area. Included were geological, geochemical, and geophysical studies by the U.S. Geological Survey and investigation of known prospects and mines by the U...
Maps showing distribution of anomalous concentrations of elements in water, Domeland Wilderness and contiguous roadless areas, Kern and Tulare counties, California Maps showing distribution of anomalous concentrations of elements in water, Domeland Wilderness and contiguous roadless areas, Kern and Tulare counties, California
The purpose of this map is to provide a geochemical framework for the mineral resource assessment of the Domeland Wilderness and contiguous roadless areas. The map shows the distribution of anomalous elements in spring and surface waters.
Maps showing distribution of anomalous concentrations of trace elements in the magnetic fraction of heavy-mineral concentrates, Domeland Wilderness and contiguous roadless areas, Kern and Tulare counties, California Maps showing distribution of anomalous concentrations of trace elements in the magnetic fraction of heavy-mineral concentrates, Domeland Wilderness and contiguous roadless areas, Kern and Tulare counties, California
The purpose of this map is to provide a geochemical framework for the mineral resource assessment of the Domeland Wilderness and contiguous roadless areas. The map shows the distribution of anomalous elements in the magnetic fraction of heavy-mineral concentrates derived from stream sediments.
Maps showing distribution of anomalous concentrations of trace elements in the nonmagnetic fraction of heavy-mineral concentrates and of uranium in the less-than-0.180-millimeter fraction of selected stream sediments, Domeland Wilderness and contiguous ro Maps showing distribution of anomalous concentrations of trace elements in the nonmagnetic fraction of heavy-mineral concentrates and of uranium in the less-than-0.180-millimeter fraction of selected stream sediments, Domeland Wilderness and contiguous ro
The purpose of this map is to provide a geochemical framework for the mineral resource assessment of the Domeland Wilderness and contiguous roadless areas. The map shows the distribution of anomalous elements in the donmagnetic fraction of heavy-mineral concentrates derived from stream sediments and uranium in selected samples of minus-80-mesh (
