Petroleum geology and resources of northeastern Mexico
James A. Peterson
1985, Circular 943
Petroleum deposits (primarily gas) in northeastern Mexico occur in two main basins, the Tertiary Burgos basin and the Mesozoic Sabinas basin. About 90 gas fields are present in the Burgos basin, which has undergone active exploration for the past 30-40 years. Production in this basin is from Oligocene and Eocene...
Hydrologic and micrometeorologic data from an unsaturated zone study at a low-level radioactive waste burial site near Barnwell, South Carolina
K.F. Dennehy, P.B. McMahon
1985, Open-File Report 85-476
Two years of selected hydrologic and micrometeorologic data collected at a low-level radioactive waste burial site near Barnwell, South Carolina are available on magnetic tape in card-image format. Hydrologic data include daily measurements of soil-moisture tension, soil-moisture specific conductance, and soil temperature at four monitoring site locations. Micrometeorlogic data include...
Geochemistry of ground-water in two sandstone aquifer systems in the Northern Great Plains in parts of Montana and Wyoming, North Dakota, and South Dakota
Thomas Henderson
1985, Professional Paper 1402-C
The Kootenai Formation in the Judith Basin, Montana, and the Lance Formation and Fox Hills Sandstone in the Powder River Basin, Wyoming, constitute two important sandstone aquifer systems in the Northern Great Plains region. Ground waters in each of these systems evolve from low dissolved-solids concentration, near-neutral pH, predominantly calcium...
Geologic characteristics of sediment- and volcanic-hosted disseminated gold deposits - Search for an occurrence model
Donald E. White, Robert O. Fournier, James J. Rytuba, Robert O. Rye, Charles G. Cunningham, Byron R. Berger, Miles L. Silberman, Harold F. Bonham Jr., Donald G. Strachan, Donald J. Birak, Robert J. Hawkins, Edwin W. Tooker
Edwin W. Tooker, editor(s)
1985, Bulletin 1646
The current expansion of resource information, particularly on "disseminated" gold, and the improved technologies now available for resource investigations should place us in an enhanced position for developing a better predictive methodology for meeting one of the important responsibilities of the U.S. Geological Survey-to examine and assess the mineral resources...
Description and preliminary testing of the CDSN Seismic Sensor Systems
Jon Peterson, Edwin E. Tilgner
1985, Open-File Report 85-288
The China Digital Seismograph Network (CDSN) is being designed and installed to provide the People's Republic of China with the facilities needed to create a national digital database for earthquake research. The CDSN, which is being developed jointly by the PRC State Seismological Bureau and the U.S. Geological Survey, will...
Approximate potentiometric surface for the aquifer unit A2, Southeastern Coastal Plain aquifer system of the United States, prior to development
V.A. Stricker
1985, Water-Resources Investigations Report 85-4019
A generalized potentiometric surface map prepared as part of the southeastern United States, Regional Sand Aquifer-System Analysis defines the altitude of water levels under conditions prior to development for aquifer unit A2, the upper group of aquifers in the sand aquifer system. Aquifer unit A2, consisting of lower Tertiary sands,...
Interpretation of geochemical data from panned concentrates of wadi sediments using R-mode factor analysis, Jabal Habashi Quadrangle, sheet 26F, Kingdom of Saudi Arabia
M. S. Allen, R.R. Tidball, R.M. Samater, G.I. Selner
1985, Open-File Report 85-5
Panned-concentrate samples from wadi sediments were collected over terranes of Precambrian age intrusive, volcanic, sedimentary, and metamorphic rocks, within the Jabal Habashi quadrangle, sheet 26F, Kingdom of Saudi Arabia. Multivariate analysis of the chemical data indicates that a significant base-metal association occurs in three areas within the quadrangle. An association...
Hydrologic data for Leviathan Mine and vicinity, Alpine County, California, 1981-83
D.P. Hammermeister, S.J. Walmsley
1985, Open-File Report 85-160
The U.S. Geological Survey collected basic hydrologic and water-quality data during 1981-83 to facilitate the geohydrologic evaluation of the Leviathan Mine area and the design of a pollution-abatement project. Surface-water field data included one or more measurements of pH, water temperature, and specific conductance at 45 sites in and adjacent...
Selected test-well data from the MX-missile siting study, Tooele, Juab, Millard, Beaver, and Iron Counties, Utah
James L. Mason, John W. Atwood, Priscilla S. Buettner
1985, Open-File Report 85-347
This report contains well data collected from 1979 to 1983 in a part of the Great Basin in western Utah (fig. 1). The area is characterized by a series of generally north-trending mountain ranges separated by alluviumfilled basins that are partially filled with sedimentary deposits eroded from the adjacent mountains...
