World conventional crude oil and natural gas: Identified reserves, undiscovered resources and futures
C.D. Masters, D. H. Root, R. M. Turner
1998, Open-File Report 98-468
This report summarizes, at the petroleum basin level, the United States Geological Survey's World Energy Program 1993 assessment of world conventional oil and gas resources. The maps provided show boundaries of petroleum basins that are referenced by the assessment, as well as, future oil and gas potential. The 'Futures' or...
Rotational and accretionary evolution of the Klamath Mountains, California and Oregon, from Devonian to present time
William P. Irwin, Edward A. Mankinen
1998, Open-File Report 98-114
The purpose of this report is to show graphically how the Klamath Mountains grew from a relatively small nucleus in Early Devonian time to its present size while rotating clockwise approximately 110°. This growth occurred by the addition of large tectonic slices of oceanic lithosphere, volcanic arcs, and melange during...
Water-level altitudes 1998, water-level changes 1977-98 and 1997-98, and compaction 1973-97 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
L.S. Coplin
1998, Open-File Report 98-96
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1977 and compaction since 1973 in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. The report, prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District,...
Water-level altitudes 1998 and water-level changes 1990-98 and 1997-98 in the Chicot and Evangeline aquifers, Fort Bend County and adjacent areas, Texas
L.S. Coplin, H. X. Santos
1998, Open-File Report 98-95
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1990 in the Chicot and Evangeline aquifers in Fort Bend County and adjacent areas, Texas. The report, prepared in cooperation with the Ford Bend Subsidence District, presents maps for the Chicot and...
A method for producing digital probabilistic seismic landslide hazard maps: An example from the Los Angeles, California, area
Randall W. Jibson, Edwin L. Harp, John A. Michael
1998, Open-File Report 98-113
The 1994 Northridge, California, earthquake is the first earthquake for which we have all of the data sets needed to conduct a rigorous regional analysis of seismic slope instability. These data sets include (1) a comprehensive inventory of triggered landslides, (2) about 200 strong-motion records of the mainshock, (3) 1:24,000-scale...
Techniques for estimating peak-flow magnitude and frequency relations for South Dakota streams
Steven K. Sando
1998, Water-Resources Investigations Report 98-4055
A generalized skew coefficient analysis was completed for South Dakota to test the validity of using the generalized skew coefficient map in Bulletin 17B of the 1982 United States Water Resources Council, ?Guidelines for Determining Flood Flow Frequency.? Results of the analysis indicate that the Bulletin 17B generalized skew coefficient...
Summary of the U.S. Geological Survey National Field Quality Assurance Program from 1979 through 1997
D.L. Stanley, T.M. Boozer, L.J. Schroder
1998, Open-File Report 98-392
Since the inception of the U.S. Geological Survey National Field Quality Assurance Program, over 85,000 proficiency samples have been analyzed by water-quality analysts. This includes more than 10,000 alkalinity samples, more than 15,000 pH samples, and more than 16,000 specific conductance samples, which were analyzed from 1990 through 1997, and...
Digital mine claim density map for Federal lands in Montana, 1996
Harry W. Campbell, Paul C. Hyndman
1998, Open-File Report 98-489
This report describes a digital map and data files generated by the U.S. Geological Survey (USGS) to provide digital spatial mining claim information for Federal lands in Montana as of March, 1997. Statewide, 159,704 claims had been recorded with the Bureau of Land Management since 1975. Of those claims, 21,055...
Database of significant deposits of gold, silver, copper, lead, and zinc in the United States
Keith R. Long, DeYoung Jr., Stephen Ludington
1998, Open-File Report 98-206-A,B
It has long been recognized that the largest mineral deposits contain most of the known mineral endowment (Singer and DeYoung, 1980). Sometimes called giant or world-class deposits, these largest deposits account for a very large share of historic and current mineral production and resources in industrial society (Singer, 1995). For...
Simulation of ground-water flow and stream-aquifer relations in the vicinity of the Savannah River Site, Georgia and South Carolina, predevelopment through 1992
John S. Clarke, Christopher T. West
1998, Water-Resources Investigations Report 98-4062
Ground-water flow and stream-aquifer relations were simulated for seven aquifers in Coastal Plain sediments in the vicinity of the U.S. Department of Energy, Savannah River Site (SRS), in Georgia and South Carolina to evaluate the potential for ground water containing hazardous materials to migrate from the SRS into Georgia through...
Low-flow characteristics and discharge profiles for selected streams in the Neuse River basin, North Carolina
J.C. Weaver
1998, Water-Resources Investigations Report 98-4135
An understanding of the magnitude and frequency of low-flow discharges is an important part of evaluating surface-water resources and planning for municipal and industrial economic expansion. Low-flow characteristics are summarized in this report for 50 continuous-record gaging stations and 113 partial-record measuring sites in the Neuse River Basin in North...
