Geochemical maps of the Ellicott Rock Wilderness and additions, South Carolina, North Carolina, and Georgia
Robert W. Luce, Henry Bell, Gertrude C. Gazdik
1985, Miscellaneous Field Studies Map 1287-A
The Ellicot Rock Wilderness comprises 3,332 acres in parts of Sumter, Nantahala and Chattahoochee National Forests. The Ellicott Rock Extension would expand wilderness boundaries in these national forests by 5,600 acres. The Ellicott Rock Extension, 5,512 acres and the Persimmon Mountain Area, 6,678 acres, are both in Sumter National Forest. ...
Mineral resource potential map of the Fossil Ridge Wilderness Study Area, Gunnison County, Colorado
Ed DeWitt, R. J. Stoneman, J. R. Clark, S.E. Kluender
1985, Miscellaneous Field Studies Map 1629-A
Parts of the Fossil Ridge Wilderness Study Area have a high resource potential for gold and silver in small deposits, uranium in medium-size deposits, and high-calcium limestone in large deposits. Parts have a moderate to high potential for uranium, thorium, and light rare-earth elements in small- to medium-size deposits, a...
Aeromagnetic maps of the Latir Peak and Wheeler Peak Wildernesses and the Columbine-Hondo Wilderness Study Area, Taos County, New Mexico
C. K. Moss, G. A. Abrams
1985, Miscellaneous Field Studies Map 1570-C
This report interprets data from a helicopter-borne magnetic survey to help delineate subsurface geology. Such data, acquired near the ground, reflect greater magnetic detail than do data acquired at higher altitude. Data from a high-altitude reconnaissance aeromagnetic survey (U.S. Geological Survey, 1976) are used selectively to assist in the interpretation...
Interpretations from multichannel seismic-reflection profiles of the deep crust crossing South Carolina and Georgia from the Appalachian Mountains to the Atlantic Coast
John C. Behrendt
1985, Miscellaneous Field Studies Map 1656
Over the past decade, the U.S. Geological Survey (USGS) has been investigating the cause of the Charleston, S.C., earthquake of 1886 and the likelihood of future earthquakes of similar magnitude (mb 6.9–7.2, Bollinger, 1977). As part of that work, multichannel reflection surveys were started in 1979 in the Charleston area,...
Reconnaissance geologic map of part of the San Isidro Quadrangle, Baja California Sur, Mexico
Hugh McLean, B.P. Hausback, J.H. Knapp
1985, Miscellaneous Field Studies Map 1799
The reconnaissance geology of part of the San Isidro 1:250,000-scale quadrangle of Baja California Sur, Mexico, was mapped in 1982, 1983, and 1984 to determine the age and stratigraphic relations of Tertiary sedimentary and volcanic rocks that comprise the bulk of the Sierra de la Giganta (southern Peninsular Ranges) and...
Stream-sediment and panned-concentrate geochemical maps of the Buffalo Peaks Wilderness Study Area, Lake, Park, and Chaffee counties, Colorado
G.A. Nowlan, W.J. Gerstel
1985, Miscellaneous Field Studies Map 1628-B
Under provisions of the Wilderness Act (Public Law 88-577, September 3, 1964), the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of areas selected for possible inclusion in the National Wilderness Preservation System. This report presents results of geochemical studies carried out in June...
Maps showing anomaly patterns for silver, molybdenum, lead, and zinc in altered rocks and soils, Williams Fork and St. Louis Peak Roadless Areas, Clear Creek, Grand, and Summit counties, Colorado
R. G. Eppinger, P. K. Theobald, H. N. Barton, R. R. Carlson
1985, Miscellaneous Field Studies Map 1588-E
The U.S. Geological Survey and the U.S Bureau of Mines conducted field studies from 1979 through 1982 to assess the mineral resource potential of the Williams Fork and St. Louis Peak Roadless Areas and the Vasquez Peak Wilderness Study Area.  Included were geological, geochemical, and geophysical studies by the U.S....
Stratigraphic cross sections and correlation of lignites in the Sentinel Butte member and upper part of the Tongue River member of the Fort Union Formation between Amidon and Fryburg, North Dakota
Jim S. Hinds
1985, Miscellaneous Field Studies Map 1765
The Austin Farm bed was once mined form an adit in the SE1/4 sec, T. 136 N., R. 101 W. Its westerly outcrop extends from that point northward along the east side and north end of the valley of Third Creek at elevations between about 2740 and 2800 ft. It...
