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...
Selected ground-water data for Yucca Mountain region, southern Nevada and eastern California, through December 1999

2001, Open-File Report 2000-479
The U.S. Geological Survey, in support of the U.S. Department of Energy, Yucca Mountain Site Characterization Project, collects, compiles, and summarizes hydrologic data in the Yucca Mountain region. The data are collected to allow assessments of ground-water resources during studies to determine the potential suitability of Yucca Mountain for storing...
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...
Quality-assurance data for routine water quality analyses by the U. S. Geological Survey laboratory in Troy, New York; July 1993 through June 1995

Volcano hazards in the Three Sisters region, Oregon
William E. Scott, R.M. Iverson, S. P. Schilling, B.J. Fisher
2001, Open-File Report 99-437
Three Sisters is one of three potentially active volcanic centers that lie close to rapidly growing communities and resort areas in Central Oregon. Two types of volcanoes exist in the Three Sisters region and each poses distinct hazards to people and property. South Sister, Middle Sister, and Broken Top, major...
Active tectonics of the Devils Mountain Fault and related structures, northern Puget Lowland and eastern Strait of Juan de Fuca region, Pacific Northwest
Samuel Y. Johnson, Shawn V. Dadisman, David C. Mosher, Richard J. Blakely, Jonathan R. Childs
2001, Professional Paper 1643
Information from marine high-resolution and conventional seismic-reflection surveys, aeromagnetic mapping, coastal exposures of Pleistocene strata, and lithologic logs of water wells is used to assess the active tectonics of the northern Puget Lowland and eastern Strait of Juan de Fuca region of the Pacific Northwest. These data indicate that 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...

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...
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....
Water-quality characteristics in the Black Hills area, South Dakota
Joyce E. Williamson, Janet M. Carter
2001, Water-Resources Investigations Report 2001-4194
This report summarizes the water-quality characteristics of ground-water and surface-water in the Black Hills area. Differences in groundwater quality by aquifer and differences in surfacewater quality by water source are presented. Ground-water characteristics are discussed individually for each of the major aquifers in the Black Hills area, referred to herein...

The Quaternary and Pliocene Yellowstone Plateau volcanic field of Wyoming, Idaho, and Montana
Robert L. Christiansen
2001, Professional Paper 729-G
This region of Yellowstone National Park has been the active focus of one of the Earth's largest magmatic systems for more than 2 million years. The resulting volcanism has been characterized by the eruption of voluminous rhyolites and subordinate basalts but virtually no lavas of intermediate composition. The magmatic system...

2001, Professional Paper 1648
Geochemical maps of the conterminous United States have been prepared for seven major elements (Al, Ca, Fe, K, Mg, Na, and Ti) and 15 trace elements (As, Ba, Cr, Cu, Hg, Li, Mn, Ni, Pb, Se, Sr, V, Y, Zn, and Zr). The maps are based on an ultra low-density...
Ground-water flow in the Gulf Coast aquifer systems, south-central United States
A. K. Williamson, H. F. Grubb
2001, Professional Paper 1416-F
The Gulf Coast regional aquifer systems constitute one of the largest, most complicated, and most interdependent aquifer systems in the United States. Ground-water flow in a 230,000-square-mile area of the south-central United States was modeled for the effect of withdrawing freshwater at the rate of nearly 10 billion gallons per...
