Mineral resource potential map of the Blanco Mountain and Black Canyon Roadless Areas, Inyo and Mono Counties, California
Michael F. Diggles, Richard J. Blakely, Richard L. Rains, Steven W. Schmauch
1983, Miscellaneous Field Studies Map 1361-C
On the basis of geologic, geochemical, and geophysical investigations and a survey of mines and prospects, the mineral resource potential for gold, silver, lead, zinc, tungsten, and barite of the Blanco Mountain and Black Canyon Roadless Areas is judged to be low to moderate, except for one local area that...
Mineral resource potential map of the Benton Range Roadless Area, Mono County, California
James L. Donahoe, Edwin D. McKee, Richard L. Rains, Donald J. Barnes, Harry W. Campbell, David K. Denton Jr., Stephen R. Iverson, Rodney E. Jeske, Scott A. Stebbins
1983, Miscellaneous Field Studies Map 1317-C
Tungsten-bearing rocks in the Benton Range Roadless Area occur in tactite lenses within the Paleozoic metasedimentary units that surround and are intruded by Triassic granodiorite of the Benton Range. High anomalous tungsten values were found in the southern part of the study area. Quartz-vein deposits with copper, lead, zinc, and...
Maps showing the distribution and relationships of selected metals in heavy-mineral concentrates of the Hells Hole Further Planning Area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico
J.R. Hassemer, K. C. Watts, C.L. Forn, E. L. Mosier
1983, Miscellaneous Field Studies Map 1344-D
The Wilderness Act (Public Law 99-577, Sept. 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 be submitted to the President...
Maps showing aeromagnetic data and interpretation for the Kalmiopsis Wilderness, southwestern Oregon
Richard J. Blakely, Norman J. Page, Floyd Gray, Lisa Senior, Holly F. Ryan
1983, Miscellaneous Field Studies Map 1240-D
The distinctive magnetic properties of the major rock types in the Kalmiopsis Wilderness of southwestern Oregon facilitate interpretation of aeromagenetic data. The region is composed of tectonic slices of magnetic ultramafic, gabboric, and other ophiolitic rocks faulted against  the realitively nonmagnetic Dothan Formation, the equivalent of the Franciscan Complex of...
Water resources data, Florida, water year 1982; Volume 3B. Southwest Florida ground water
R.T. Mycyk, L.D. Fayard, W.L. Fletcher, J.K. Ogle
1983, Water Data Report FL-82-3B
Water resources data for the 1981 water year for southwest Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
Biostratigraphic correlation chart of some Upper Cretaceous rocks from the Lost Soldier area, Wyoming to west of Craig, Colorado
J.W. Bader, J. R. Gill, W. A. Cobban, B. E. Law
1983, Miscellaneous Field Studies Map 1548
This chart depicts the time-stratigraphic relations of some Upper Cretaceous rocks along the eastern and southeastern margins of the Greater Green River Basin, south-central Wyoming and northwestern Colorado. The purpose of this report is to release a preferred set of correlations based upon marine mollusk biostratigraphy. The senior author, with...
