Maps showing geology, oil and gas fields, and geologic provinces of the Asia Pacific region
This digitally compiled maps include geology, geologic provinces, and oil and gas fields of the Asia Pacific Region. The map is part of a worldwide series of maps on CD-ROM released by the U.S. Geological Survey's World Energy Project. The goal of the project is to assess the undiscovered, technically recoverable oil and gas resources of the world and report these results by the year 2000. For dat

Hydrogeology of the unsaturated zone, North Ramp area of the Exploratory Studies Facility, Yucca Mountain, Nevada
Yucca Mountain, in southern Nevada, is being investigated by the U.S. Department of Energy as a potential site for a repository for high-level radioactive waste. This report documents the results of surface-based geologic, pneumatic, hydrologic, and geochemical studies conducted during 1992 to 1996 by the U.S. Geological Survey in the vicinity of the North Ramp of the Exploratory Studies Facility

Geological map of Washington - Southwest quadrant (digital edition)
This report comprises digital spatial data that constitute a partial transcription of the 1:250,000-scale Geologic map of Washington - southwest quadrant (Walsh and others, 1987); digital base material, symbolsets, and ARC Macro Language (AML) procedures to create a geologic map on a shaded-relief base from the digital spatial data; and Postscript and RTL plotfiles for such a geologic map.

Digital elevation model (DEM) of Cascadia, latitude 39N-53N, longitude 116W-133W
This report contains a 250-meter digital elevation model (DEM) for Cascadia (latitude 39N - 53N, longitude 116W - 133W), a region that encompasses the Cascade volcanic arc, the Cascadia subduction zone, and the Juan de Fuca Ridge system. The DEM is distributed as file cascdem.tar.gz (39 MB; 78MB uncompressed).

Characterization of fly ash from low-sulfur and high-sulfur coal sources: Partitioning of carbon and trace elements with particle size
Fly ash samples were collected in November and December of 1994, from generating units at a Kentucky power station using high- and low-sulfur feed coals. The samples are part of a two-year study of the coal and coal combustion byproducts from the power station. The ashes were wet screened at 100, 200, 325, and 500 mesh (150, 75, 42, and 25 mu m, respectively). The size fractions were then dried, w

Geologic datasets for weights of evidence analysis in northeast Washington: 3. Minerals-related permits on national forests, 1967 to 1998
Permits to explore for and (or) develop mineral resources on forest land can be used to indicate locations and types of mineral-related activities on national forests. Permits for these activities require filing at the Forest Service a Notice of Intention (Notice) to conduct mineral exploration activities and (or) a Plan of Operation (Plan). A Plan of Operation is required is significant activitie

Geometry, structure, and concealed lithology of the San Rafael Basin, southeastern Arizona
The contiguous United States has been well explored for exposed conventional mineral deposits. Therefore, it is likely that many economically viable and strategically significant conventional undiscovered mineral deposits will be found in bedrock concealed beneath basin sediments. Mineral resource assessments must incorporate an understanding of the geometry, structure, and concealed lithology of

Inversion of gravity data to define the pre-Tertiary surface and regional structures possibly influencing ground-water flow in the Pahute Mesa-Oasis Valley region, Nye County, Nevada
A three-dimensional inversion of gravity data from the Pahute Mesa–Oasis Valley region reveals a topographically complex pre-Tertiary basement surface. Beneath Pahute Mesa, the thickness of the Tertiary volcanic deposits may exceed 5 km within the Silent Canyon caldera complex. South of Pahute Mesa in Oasis Valley, basement is shallower (< 1 km) but between this valley and the Timber Mountain cald

Geologic framework for the Puget Sound aquifer system, Washington and British Columbia
The Puget-Willamette study area is composed of two distinct subareas, the Puget Sound Lowland and the Willamette Lowland. The study area for this report is the Puget Sound Lowland, which is located in western Washington and in a small part of southwestern British Columbia, Canada. The lowland encompasses an area of about 17,610 square miles and contains about 2,615 square miles of saltwater. The u
