Index of faults of Cretaceous and Cenozoic age in the eastern United States
David C. Prowell
1983, Miscellaneous Field Studies Map 1269
The information in this report was collected between 1974 and 1982 as part of the Reactor Hazards Program of the U.S. Geological Survey (USGS). This program was initiated to delineate and assess geologic hazards that could be particularly detrimental to major constructions, especially nuclear reactors. Faults are of principal interest...
Map and interpretation of geochemical anomalies in the White Mountains, Blanco Mountain, Birch Creek, and Black Canyon Roadless Areas, White Mountains, California and Nevada
Michael F. Diggles
1983, Miscellaneous Field Studies Map 1361-B
The geochemical results show the most anomalous part of the study area to be the White Mountain Fault zone along the northwestern range front.  Silver, lead, and zinc mineralization in calcareous rocks, porphyry copper in dikes, gold-arsenic quartz vein deposits, tungsten and molybdenum tactite mineralization, and argillic alteration zones are...
Aeromagnetic map of the Arnold Mesa Roadless Area, Yavapai County, Arizona
Willard E. Davis, Edward W. Wolfe
1983, Miscellaneous Field Studies Map 1577-D
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 resource potential. Results must be made available to the public and be submitted to the President and...
Geochemical maps of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana
Berton W. Coxe, Margo I. Toth
1983, Miscellaneous Field Studies Map 1495-C
The Selway-Bitterroot Wilderness covers almost 2,000 mi2 in east-central Idaho and western Montana (fig. 1). The wilderness lies across the Bitterroot Range, which forms the boundary between Idaho and Montana, and includes large portions of the drainages of the Selway, Lochsa, and Bitterroot Rivers. Elevations range from 1,800 ft on...
Mineral resource potential map of the Raywood Flat Roadless Areas, Riverside and San Bernardino counties, California
Jonathan C. Matti, Brett F. Cox, Stephen R. Iverson
1983, Miscellaneous Field Studies Map 1563-A
Geologic, geochemical, and geophysical studies within the Raywood "Flat Roadless Areas, together with an investigation of mines and prospects within the further planning area, resulted in (1) identification of nonmetallic mineral resources at a marble mine in the further planning area and (2) recognition of a small area in the...
Maps showing geology and shallow structure of western Rhode Island Sound, Rhode Island
Sally W. Needell, Charles J. O’Hara, Harley J. Knebel
1983, Miscellaneous Field Studies Map 1537
This report presents the results of a high-resolution, seismic-reflection, and sidescan-sonar survey conducted in western Rhode Island Sound south of Narragansett Bay (fig. 1 inset) by the U.S. Geological Survey in 1980. The study defines the geologic framework of the Atlantic Inner Continental Shelf between lat. 41°09' and 41°32'N and...
Mineral resource potential map of the Natural Area Roadless Area, Baker County, Florida
James B. Cathcart, Sam H. Patterson, Thomas M. Crandall
1983, Miscellaneous Field Studies Map 1572-B
The Natural Area Roadless Area, which is in the Osceola National Forest in Baker County, Fla., is underlain by sedimentary rocks containing phosphate deposits that are not a potential mineral resource by todays standards. The region has a low potential for oil and gas and virtually no potential for other...
Map showing characteristics of lode gold in the Medford 1 degree by 2 degrees Quadrangle, Oregon-California
Norman J. Page, Maureen G. Johnson, Jocelyn A. Peterson
1983, Miscellaneous Field Studies Map 1383-D
About 500 lode gold occurrences, prospects, and mines have been reported from the Medford 1o x 2o quadrangle, Oregon-California. Summary descriptions of individual lode gold deposits and districts which include those occurrences in the Medford 1o x 2o quadrangle have been published by Brooks and Ramp (1968) and Hotz (1971) and by others cited in...
Seismicity map of the State of Virginia
B.G. Reagor, C. W. Stover, S. T. Algermissen
1983, Miscellaneous Field Studies Map 1346
The data shown on this map and listed in table 1 are for earthquakes that were originally included in a study of seismic risk in the United States (Algermissen, 1969).  This data file has been recompiled and updated through 1980.  Some revisions of epicenters and intensities in the original file...
Reconnaissance map showing thickness of volcanic ash deposits in the greater Hilo area, Hawaii
Jane M. Buchanan-Banks
1983, Miscellaneous Field Studies Map 1499
This study was undertaken to determine the thickness and distribution of volcanic ash deposits in the greater Hilo area, Hawaii, as a step toward evaluating their susceptibility to failure during earthquake shaking. On several occasions their instability has resulted in serious damage. For example, the 1868 earthquake (m=7+), following a...
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...
