Map showing a deep-tow geophysical study of the north end of the San Clemente Fault, California Borderland Map showing a deep-tow geophysical study of the north end of the San Clemente Fault, California Borderland

A deep-tow geophysical study of a small ridge along the north end of the San Clemente fault, informally termed Kimki Ridge by Arne Junger and J.G. Vedder (unpub. data, 1979), was conducted in April 1976 using the R/V Melville of the Scripps Institution of Oceanography. The purpose of the survey was to search for evidence of active faulting along the north-ward extension of the San...

Map showing general chemical quality of surface water in the Alton-Kolob coal-fields area, Utah Map showing general chemical quality of surface water in the Alton-Kolob coal-fields area, Utah

This is one of a series of maps that describes the geology and related natural resources of the Alton-Kolob coal-fields area, Utah. The purpose of this map is to show the general chemical quality of surface water in the area by ranges of dissolved-solids concentrations (salinity) known or assumed to occur in the water.

Map showing general chemical quality of surface water in the Richfield Quadrangle, Utah Map showing general chemical quality of surface water in the Richfield Quadrangle, Utah

This is one of a series of maps that describe the geology and related natural resources of the Richfield 2° quadrangle, Utah. The purpose of this map is to show the general chemical quality of surface water in the area by ranges of dissolved-solids concentrations. Data used to compile this map were collected by the U.S. Geological Survey in cooperation with the Utah Department of Natural...

Map showing the distribution of minerals in the heavy-mineral concentrate of stream sediments in the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona Map showing the distribution of minerals in the heavy-mineral concentrate of stream sediments in the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona

Reconnaissance geochemical and mineralogical sampling was done in the Sierra Ancha Wilderness and Salome Study Area during April and May 1978. This map shows the distribution of chalcopyrite, florite, galena, scheelite, and lead-rich iron oxides in the nonmagnetic fraction of the heavy-mineral concentrate of stream sediment samples collected during the reconnaissance study.
