Mineral resource potential map of the Savannah Roadless Area, Liberty County, Florida
Sam H. Patterson, Walter Schmidt, Thomas M. Crandall
1982, Miscellaneous Field Studies Map 1470
The Savannah Roadless Area is underlain by sedimentary rocks having low potential for oil and gas and minerals. The low potential for oil or gas notwithstanding, the possibilities for discovery cannot be ruled out because the area and nearby lands have not been thoroughly explored. No minerals have been mined...
Mineral resource potential map of the John Muir Wilderness, Fresno, Inyo, Madera, and Mono counties, California
E. A. Du Bray, D. A. Dellinger, M. F. Diggles, H. W. Oliver, F. L. Johnson, H. K. Thurber, R.W. Morris, T.J. Perers, D.S. Lindsey
1982, Miscellaneous Field Studies Map 1185-C
Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild,"...
Carolina Trough structure contour maps
Charles K. Paull, William P. Dillon
1982, Miscellaneous Field Studies Map 1402
Four strong reflection horizons identified on multichannel seismic-reflection profiles of the U.S. continental margin east of the Carolinas have been traced and contoured (maps A-D).  Depths, in kilometers, to the horizons were calculated by the method of Taner and Koehler (1969) using the reflection-time and RMS (root-mean-square) velocities from multichannel...
Mineral resource potential map of the Ramseys Draft Addition, Augusta and Highland counties, Virginia
F. G. Lesure, P. C. Mory
1982, Miscellaneous Field Studies Map 1369-C
Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild,"...
Maps showing geochemical analyses of the Ishi, Mill Creek, Polk Springs, and Butt Mountain further planning areas, Tehama and Plumas counties, California
Jocelyn A. Peterson, Robin Bradley, K. A. Johnson
1982, Miscellaneous Field Studies Map 1340-B
The Ishi, Mill Creek, Polk Springs, and Butt Mountain Further Planning Areas occupy part of the region between Chico and Mount Lassen (fig. 1).  All of these areas are characterized by thick sequences of Tertiary and Quaternary pyroclastic and lava flows, predominantly of the Pliocene Tuscan Formation,...
Map showing surface ruptures associated with the Mammoth Lakes, California, earthquakes of May 1980
M. M. Clark, J. C. Yount, P.R. Vaughn, R.L. Zepeda
1982, Miscellaneous Field Studies Map 1396
This map shows surface ruptures associated with the M 6 Mammoth Lakes earthquakes of May 25-27, 1980 (Sherburne, 1980). The ruptures were mapped during USGS field investigations May 28 to June 4 and July 14-19, 1980. The map also includes some of the ruptures recorded by California Division of Mines and Geology...
Pre-Monterey subcrop and structure contour maps, western San Luis Obispo and Santa Barbara Counties, south-central California
C.A. Hall Jr.
1982, Miscellaneous Field Studies Map 1384
Pre-Monterey (Miocene) subcrop and structure contour maps have been compiled from existing maps and well-hole data to depict the distribution of rocks that lie beneath the Monterey Formation and on which Tertiary rocks were deposited. These maps indicate the general topography of the sea floor when the Monterey Formation was...
Geochemical survey of the Dolly Ann Roadless Area, Alleghany County, Virginia
Frank G. Lesure
1982, Miscellaneous Field Studies Map 1358-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Dolly Ann Roadless Area (fig. 1) to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos. Similar geochemical surveys based on trace-element analyses have been credited with the discovery of many types...
Map showing sampled radiolarian localities in the western Paleozoic and Triassic belt, Klamath Mountains, California
William P. Irwin, David L. Jones, Charles D. Blome
1982, Miscellaneous Field Studies Map 1399
The western Paleozoic and Triassic belt, the largest of several major subdivisions of the Klamath Mountains geologic province, extends 300 km northward from the south end of the province in California to the north end of the province in Oregon (see inset map). The rocks of the belt are mainly...
Mineral resources potential map of the Lost Cove and Harper Creek Roadless Areas, Avery and Caldwell counties, North Carolina
T.M. Crandall, R. B. Ross, J. W. Whitlow, W. R. Griffitts
1982, Miscellaneous Field Studies Map 1391-A
A geologic, geophysical, and geochemical investigation and a survey of mines, quarries, and prospects have been conducted to evaluate the mineral resource potential of the Lost Cove and Harper Creek Roadless Areas, Avery and Caldwell Counties, North Carolina. The study area lies within the Blue Ridge physiographic province and is...
Mineral resource potential of the Granite Chief Wilderness Study Area, Placer County, California
David S. Harwood, Francis E. Federspiel, Eric E. Cather, Douglas F. Scott
1982, Miscellaneous Field Studies Map 1273-C
A mineral resource survey of the Granite Chief Wilderness Study Area in the Tahoe National Forest and Lake Tahoe Management Area was conducted between 1979 and 1981. The mineral resource potential of the area was evaluated from geologic and geochemical studies by the U.S. Geological Survey, and from the examination...
