Hydrogeologic framework of Antelope Valley and Bedell Flat, Washoe County, west-central Nevada
D.L. Berger, D. A. Ponce, W.C. Ross
2001, Water-Resources Investigations Report 2001-4220
Description of the hydrogeologic framework of Antelope Valley and Bedell Flat in west-central Nevada adds to the general knowledge of regional ground-water flow north of the Reno-Sparks metropolitan area. The hydrogeologic framework is defined by the rocks and deposits that transmit ground water or impede its movement and by the...
Geologic Map of the Hellas Region of Mars
Gregory J. Leonard, Kenneth L. Tanaka
2001, IMAP 2694
INTRODUCTION This geologic map of the Hellas region focuses on the stratigraphic, structural, and erosional histories associated with the largest well-preserved impact basin on Mars. Along with the uplifted rim and huge, partly infilled inner basin (Hellas Planitia) of the Hellas basin impact structure, the map region includes areas of ancient...
Water-level altitudes 2001 and water-level changes 1990-2001 and 2000-2001 in the Chicot and Evangeline aquifers, Fort Bend County and adjacent areas, Texas
L.S. Coplin, Natalie A. Houston
2001, Open-File Report 2001-93
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 Fort Bend Subsidence District, presents maps for the Chicot and...
Petroleum geology and resources of the Baykit High province, East Siberia, Russia
Gregory F. Ulmishek
2001, Bulletin 2201-F
The Baykit High province consists of two principal structural units?the Baykit regional high in the west, which occupies most of the province, and the Katanga structural saddle in the east. The province is on the western margin of the Siberian craton east of theYenisey Ridge foldbelt. The province is an exploration...
Petroleum geology and resources of the Dnieper-Donets Basin, Ukraine and Russia
Gregory F. Ulmishek
2001, Bulletin 2201-E
The Dnieper-Donets basin is almost entirely in Ukraine, and it is the principal producer of hydrocarbons in that country. A small southeastern part of the basin is in Russia. The basin is bounded by the Voronezh high of the Russian craton to the northeast and by the Ukrainian shield to...
Water-level altitudes 2001, water-level changes 1977-2001 and 2000-2001, and compaction 1973-2000 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
L.S. Coplin, Natalie A. Houston, Dexter W. Brown
2001, Open-File Report 2001-94
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,...
Petroleum geology and resources of the Nepa-Botuoba High, Angara-Lena Terrace, and Cis-Patom Foredeep, southeastern Siberian Craton, Russia
Gregory F. Ulmishek
2001, Bulletin 2201-C
Three structural provinces of this report, the Nepa-Botuoba High, the Angara-Lena Terrace, and the Cis-Patom Foredeep, occupy the southeastern part of the Siberian craton northwest of the Baikal-Patom folded region (fig. 1). The provinces are similar in many aspects of their history of development, stratigraphic composition, and petroleum geology characteristics....
Global GIS database. Digital atlas of South Asia
Paul Hearn, T.M. Hare, P. Schruben, D. Sherrill, C. LaMar, P. Tsushima
2001, Data Series 62-C
This CD-ROM contains a digital atlas of the countries of South Asia. This atlas is part of a global database compiled from USGS and other data sources at a nominal scale 1:1 million and is intended to be used as a regional-scale reference and analytical tool by government officials, researchers,...
Evaluation of ground-water/surface-water relations, Chapman Creek,West-Central Ohio, by means of multiple methods
Denise H. Dumouchelle
2001, Water-Resources Investigations Report 2001–4202
Chapman Creek, a tributary to the Mad River, passes within about 500 feet of a landfill near Tremont City, in Clark County, west-central Ohio. In autumn 2000, the ground-water/surface-water relation was investigated by use of piezometers, seepage meters, temperature monitors, and a gain-loss study. Four piezometers were installed in the...
Origin, extent, and thickness of quaternary geologic units in the Willamette Valley, Oregon
Jim E. O'Connor, Andrei M. Sarna-Wojcicki, Karl C. Wozniak, Danial J. Polette, Robert J. Fleck
2001, Professional Paper 1620
Stratigraphic and chronologic information collected for Quaternary deposits in the Willamette Valley, Oregon, provides a revised stratigraphic framework that serves as a basis for a 1:250,000-scale map, as well as for thickness estimates of widespread Quaternary geologic units. We have mapped 11 separate Quaternary units that are differentiated on the...
Deep regional resistivity structure across the Battle Mountain-Eureka and Carlin trends, north-central Nevada
Brian D. Rodriguez, Jackie M. Williams
2001, Open-File Report 2001-346
Magnetotelluric data collected along four, regional scale, southwest-to-northeast profiles show deep resistivity structures beneath the Battle Mountain-Eureka and Carlin gold trends in north-central Nevada, which appear consistent with tectonic breaks in the crust that possibly served as channels for hydrothermal fluids. It seems likely that gold deposits along these linear...
