Geochemical survey of the Cohutta Wilderness and the Hemp Top Roadless Area, northern Georgia and southeastern Tennessee
The contiguous Cohutta Wilderness and Hemp Top Roadless Area are in the western part of the Blue Ridge physiographic province of northern Georgia and southeastern Tennessee (fig. 1). All of the study area is in Georgia except an irregular strip of land about 1 mi at its widest on the northern end of the Cohutta Wilderness in Tennessee. The area of the Cohutta Wilderness is 34,650 acres; that of
Geochemical survey of the Dolly Ann Roadless Area, Alleghany County, Virginia
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Dolly Ann Roadless Area (fig. 1) to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos. Similar geochemical surveys based on trace-element analyses have been credited with the discovery of many types of mineral deposits (Hawkes and Webb, 1962). No metallic mineral de
Geochemical survey of the James River Face Wilderness, Bedford and Rockbridge counties, Virginia
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a geochemical survey of the James Rive
Geochemical survey of the Ramseys Draft Addition, Augusta and Highland counties, Virginia
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Ramseys Draft Addition (fig.1) to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos. Thirty-three stream-sediment, two soil, and 22 rock samples were collected from the addition during the earlier study of Ramseys Draft Wilderness Study Area (Lesure and others, 197
Geologic and structure map of the Choteau 1° x 2° quadrangle, western Montana: A digital database
The geologic and structure map of Choteau 1 x 2 degree quadrangle (Mudge and others, 1982) was originally converted to a digital format by Jeff Silkwood (U.S. Forest Service and completed by the U.S. Geological Survey staff and contractor at the Spokane Field Office (WA) in 2000 for input into a geographic information system (GIS). The resulting digital geologic map (GIS) database can be queried
