Geochemical map of the North Fork John Day River Roadless Area, Grant County, Oregon Geochemical map of the North Fork John Day River Roadless Area, Grant County, Oregon
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 submitted to the President and the Congress. This report presents the analytical results of a geochemical survey...
Geochemical maps showing distribution and abundance of barium in two fractions of stream-sediment concentrates, Silver City 1 degree by 2 degrees Quadrangle, New Mexico and Arizona Geochemical maps showing distribution and abundance of barium in two fractions of stream-sediment concentrates, Silver City 1 degree by 2 degrees Quadrangle, New Mexico and Arizona
These maps (Maps A and B) show the distribution and abundance barium in the nonmagnetic and magnetic fractions of heavy-mineral concentrates from stream sediments collected in the Silver City 1o x 2o quadrangle, New Mexico and Arizona. Geochemical maps showing the distribution and abundance of 10 other selected key elements and the mineral fluorite in the Silver City quadrangle are also...
