The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Blood Mountain Roadless Area to search for unexposed mineral deposits which might be recognized by a geochemical signature in the abundance of distribution patterns of trace elements. Forty five fine-grained stream-sediment samples and 45 panned-concentrate samples were collected in the Blood Mountain study area (fig

Geochemical survey of the Chattahoochee Roadless Area, Towns, Union, and White counties, Georgia

Th U.S. Geological Survey made a reconnaissance geochemical survey of the Chattahoochee Roadless Area (fig. 1) to search for unexposed mineral deposits which might be recognized by a geochemical signature in the abundance or distribution patterns of trace elements. As part of a regional geochemical reconnaissance, M/ Hurst (University of Georgia) collected 51 fine-grained stream-sediment samples a
