Map showing mineral resource potential of the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona Map showing mineral resource potential of the Sierra Ancha Wilderness and Salome Study Area, Gila County, Arizona
The Wilderness Act (Public Law 88-577, Sept. 3, 1964) and certain related Acts require the Geological Survey and the 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 Administration and the Congress. These maps and reports present the results of a geologic and...
Map showing mineral-resource potential of the King Range and Chemise Mountain Instant Study Areas, Humboldt and Mendocino counties, California Map showing mineral-resource potential of the King Range and Chemise Mountain Instant Study Areas, Humboldt and Mendocino counties, California
The potential for economic development of energy-related or metallic mineral resources in the King Range and Chemise Mountain Instant Study Areas is low to moderate as indicated by geologic, geophysical, and geochemical investigations. No oil or gas seeps or coal seams were detected within the King Range or Chemise Mountain Study Area. The low porosity and permeability of the Franciscan...
Map showing paleontological control of Paleozoic stratigraphy in New England Map showing paleontological control of Paleozoic stratigraphy in New England
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology. Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking. This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of New England.
Map showing reconnaissance geochemistry in the gold-pyrophyllite belt of northwestern Moore County, North Carolina Map showing reconnaissance geochemistry in the gold-pyrophyllite belt of northwestern Moore County, North Carolina
Traces of gold and molybdenum are widely disseminated in an area approximately 35 km long and 10 km wide in northwestern Moore County, N.C. At least 2540 oz. of gold were recovered from 16 or more mines and prospects between 1880 and 1910. One hundred and ninety rock samples out of 244 collected from old gold mines, pyrophyllite deposits and along roads contain gold quantities ranging...
