Maps showing distribution of copper, lead, zinc, cadmium, and silver in samples of minus-60-mesh (0.25-MM) stream sediment and nonmagnetic heavy-mineral concentrate, Walker Lake 1 degree by 2 degrees Quadrangle, California and Nevada
M.A. Chaffee, R. H. Hill, S. J. Sutley
1988, Miscellaneous Field Studies Map 1382-G
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...
Descriptive and grade-tonnage models of volcanogenic manganese deposits in oceanic environments; a modification
Dan L. Mosier, Norman J. Page
1988, Bulletin 1811
Four types of volcanogenic manganese deposits, distinguished on the basis of geologic, geochemical, and geophysical characteristics, appear to result from a combination of volcanic and hydrothermal processes related to hot-spring activity in oceanic environments. We compare these four desposit types, here called the Franciscan, Cuban, Olympic Peninsula, and Cyprus,...
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 Nevada

Geochemical survey of the Tray Mountain Roadless Area, northern Georgia
R. P. Koeppen, A. E. Nelson
1988, Miscellaneous Field Studies Map 1347-B
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral values, if any, that might be present.  Results must be made available to the public and be...
Map of fault scarps formed in unconsolidated sediments, Tooele 1 degree by 2 degrees quadrangle, northwestern Utah
T. P. Barnhard, R.L. Dodge
1988, Miscellaneous Field Studies Map 1990
This report is one of a series of studies of western Utah (Anderson and Bucknam, 1979; Bucknam and Anderson, 1979b), eastern Nevada (Barnhard, 1985), and central Nevada (Wallace, 1979) that shows the distribution, relative age, and amount and extent of surface rupture on Quaternary fault scarps. Previous paleoseismicity studies in...
