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.

Interpretations from multichannel seismic-reflection profiles of the deep crust crossing South Carolina and Georgia from the Appalachian Mountains to the Atlantic Coast Interpretations from multichannel seismic-reflection profiles of the deep crust crossing South Carolina and Georgia from the Appalachian Mountains to the Atlantic Coast
Over the past decade, the U.S. Geological Survey (USGS) has been investigating the cause of the Charleston, S.C., earthquake of 1886 and the likelihood of future earthquakes of similar magnitude (mb 6.9–7.2, Bollinger, 1977). As part of that work, multichannel reflection surveys were started in 1979 in the Charleston area, on 1 and (Behrendt and others, 1981; Hamilton and others, 1983)...

Map of fault scarps formed in unconsolidated sediments, Elko 1 degree by 2 degrees Quadrangle, Nevada and Utah Map of fault scarps formed in unconsolidated sediments, Elko 1 degree by 2 degrees Quadrangle, Nevada and Utah
The accompanying map shows nine areas where fault scarps formed in unconsolidated sediments in the Elko 1°x2° quadrangle, northeastern Nevada and westernmost Utah. The faulted sediments include pebbly to bouldery colluvium, alluvium, and pediment gravels. They are inferred to have been deposited in Quaternary time during the last phase of basin-filling sedimentation.
Map showing abundance and distribution of arsenic in oxide residues of stream-sediment samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California Map showing abundance and distribution of arsenic in oxide residues of stream-sediment samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California
Stream-sediment sampling in the Medford 1o x 2o quadrangle was undertaken to provide to aid in assessment of the mineral resource potential of the quadrangle. This map presents data on the abundance and distribution of copper in the oxide residues (oxalic-acid leachates) of stream sediments and in the minus-0.18-mm sieve fraction of selected stream sediments collected in the quadrangle.
Map showing abundance and distribution of chromium in stream-sediment samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California Map showing abundance and distribution of chromium in stream-sediment samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California
The Medford quadrangle is located in mountainous southwestern Oregon adjacent to the California border and a short distance east of the Pacific coast. Various parts of this area lie in different geologic provinces. Most of the western half of the quadrangle is underlain by pre-Tertiary rocks of the Klamath Mountains province. However, the Coast Range province is represented by the...
