Maps showing distribution of iron, cobalt, barium, strontium, arsenic, antimony, and bismuth in samples of minus-60-mesh (0.25-MM) stream sediment and (or) nonmagnetic heavy-mineral concentrate, Walker Lake 1 degree by 2 degrees Quadrangle, California and
This report is part of a folio of maps of the Walker Lake 1o x 2o quadrangle, California and Nevada, prepared under the Conterminous United States Mineral Assessment Program. The folio includes geological, geochemical, and geophysical maps, as well as mineral resources assessment maps, which identify selected known or possible mineral-deposit environments in the quadrangle. The geochemical maps sh

Mineral resource potential map of the Pecos Wilderness, Santa Fe, San Miguel, Mora, Rio Arriba, and Taos Counties, New Mexico
The Pecos Wilderness covers approximately 348 sq mi in the Santa Fe and Carson National Forests, north-central New Mexico. The area investigated includes the wilderness and approximately 150 sq mi of adjacent territory. The additional area covers several RARE II Road less Areas that were classified by the U.S. Forest Service in 1979 as Proposed Wilderness and Further Planning Areas, but were not i
Mineral resources and resource potential map of the Pyramid Peak Roadless Area, Riverside County, California
The Pyramid Peak Roadless Area is underlain by mid-Cretaceous plutonic rocks (granite, granodiorite, and tonalite) that intrude metasedimentary rocks of the Desert Divide Group. The granodiorite grades eastward into strongly deformed mylonitic rocks mapped as part of the Santa Rosa mylonite zone. Metasedimentary rocks, orthogneiss, and anatexites of the Palm Canyon Complex were displaced westward
Mines, prospects, and mineral sites, wilderness and RARE II areas, White Mountain National Forest, New Hampshire
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 value, if any, that may be present. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of investigations of mines,
Phanerozoic structural features in the northern Midcontinent, U.S.A.
Because Precambrian structural features may represent controls for undiscovered mineral deposits hosted by Phanerozoic sedimentary rocks, this map was prepared to evaluate the possibility of locating Precambrian structural features by their expression in the structures of the overlying Phanerozoic rocks. The map includes most known Phanerozoic structural features in the region: areas of Phanerozoi
