Reconnaissance geologic study of the Vazante zinc district, Minas Gerais, Brazil
Charles H. Thorman, Samir Nahass
1977, Open-File Report 77-630
The Vazante district, Minas Gerais, 130 km south of Paracatu, produces nearly all of Brazil's zinc metal. The district is situated on the western side of the Late Precambrian Bambul basin and along the eastern and leading edge of the north-trending Brazilian orogenic belt (ca. 600-500 m.y. old) that borders...
GEOTHERM user guide
James R. Swanson
1977, Open-File Report 77-504
GEOTHERM is a computerized geothermal resources file developed by the U.S. Geological Survey. The file contains data on geothermal fields, wells, and chemical analyses from the United states and international sources. The General Information Processing System (GIPSY) in the IBM 370/155 computer is used to store and retrieve data. The...
Ground-water resources and geology of Colquitt County, Georgia
E. A. Zimmerman
1977, Open-File Report 77-56
Limestone beds of Eocene, Oligocene, and lower Miocene age, called the principal artesian aquifer, are the chief source of ground water for Colquitt County. Because streams are small, undependable and relatively inaccessible to most users, ground water is the most important source for increased industrial and agricultural water use. Southeast...
Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass
Robert A. Zielinski
1977, Open-File Report 77-744
This report concerns investigations designed to identify the important physical and chemical parameters influencing the rate of release of uranium from glass shards of rhyolitic air-fall ash. Oxidizing, silica undersaturated, alkaline solutions are eluted through a column of rhyolitic glass shards at a carefully controlled temperature, pressure, and flow rate....
A brief investigation of the surface-water hydrology of Yemen Arab Republic
Henry Chiles Riggs
1977, Open-File Report 77-150
Yemen, near the southwest tip of the Arabian Peninsula, is a mountainous country bordered by a desert on the east and a coastal plain on the west. Rainfall is low and seasonal; consequently, most streams (wadis) are ephemeral. The natural flow regimens of many of the smaller wadis are modified...
Summary of results of frictional sliding studies, at confining pressures up to 6.98 kb, in selected rock materials
R. Summers, J. Byerlee
1977, Open-File Report 77-142
This report is a collection of stress-strain charts which were produced by deforming selected simuiated fault gouge materials. Several sets of samples consisted of intact cylinders, 1.000 inch in diameter and 2.500 inches long. The majority of the samples consisted of thin layers of the selected sample material, inserted within...
Subsurface-temperature data for some wells in western Utah
F. Eugene Rush
1977, Open-File Report 77-132
The data contained in this report were gathered as part of a hydrothermal reconnaissance of the State of Utah. These data, plus additional data and information, will form the basis for a future interpretive report. These data are being released separately from and prior to the interpretive report, to make...
Evaporation and radiation measurements at Salton Sea, California
Alex M. Sturrock
1977, Open-File Report 77-74
Evaporation from the Salton Sea, Calif., was computed for a 539-day period between July 14, 1967, and January 2, 1969, by use of energy-budget, mass-transfer, and water budget methods. The total evaporation computed by the three methods agreed within 5 percent. The values of heat transfer to and from the...
Hydrologic monitoring of a waste-injection well near Milton, Florida, June 1975 - December 1976
Charles A. Pascale, J.B. Martin
1977, Open-File Report 77-368
Hydraulic and chemical data were collected through a monitoring program conducted by the U.S. Geological Survey at an industrial liquid-waste injection site 6 mi southwest of Milton, Fla., in Santa Rosa County. The injection system is described. Data include injection rates, volumes, and pressures; water-level data at three monitor wells...
Computer program for the calculation of grain size statistics by the method of moments
Michael B. Sawyer
1977, Open-File Report 77-580
A computer program is presented for a Hewlett-Packard Model 9830A desk-top calculator (1) which calculates statistics using weight or point count data from a grain-size analysis. The program uses the method of moments in contrast to the more commonly used but less inclusive graphic method of Folk and Ward (1957). The...
Water table in the surficial aquifer and potentiometric surface of the Floridan Aquifer in selected well fields, west-central Florida, September 1976
Paul D. Ryder, L. R. Mills
1977, Open-File Report 77-551
The water table in the surficial aquifer and the potentiometric surface of the Florida aquifer in a 1200 square-mile area in west-central Florida are mapped semiannually by the U. S. Geological Survey. Maps are prepared on the basis of water levels measured in wells each May to coincide with seasonal...
Atlantic Margin Coring Project 1976: Preliminary Report on Shipboard and Some Laboratory Geotechnical data
Adrian F. Richards
1977, Open-File Report 78-123
This report presents reduced shipboard geotechnical data collected during the 1976 Atlantic Margin Coring Project; results of laboratory tests of specific gravity, water content, bulk density, and Atterberg limits; and sedimentation-compression e log p curves showing consolidation. A description of the procedures used at sea and in the laboratory and...
