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...

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...
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...
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....

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...

2001, Circular 1196-A
In 1998, 175 metric tons (t) of refined gold was recovered by U.S. refiners from old and new scrap. The overall recycling rate was 29 percent when scrap consumption was compared with apparent domestic supply. Sources of old scrap includes discarded jewelry, dental materials, plating solutions, and electronic equipment. A...
