Preliminary report on gold deposits at Meshaheed, Kingdom of Saudi Arabia
C. W. Smith, R.M. Samater
1985, Open-File Report 85-9
A fault-controlled, hydrothermal system deposited gold, stibnite, and quartz in metasediments, intrusive basalt, and diorite in an area approximately 3 by 5 km in the Meshaheed area of the northeastern Arabian Shield. Veins in metasediments appear to be lenticular and average less than 1 m thick. A related, quartz-pyrite stockwork...
Approximate potentiometric surface for the aquifer unit A4, southeastern coastal plain aquifer system of the United States, prior to development
V.A. Stricker, Walter R. Aucott, Robert E. Faye, John S. Williams, Michael J. Mallory
1985, Water-Resources Investigations Report 84-4364
A generalized potentiometric surface map prepared as part of a regional analysis of sand aquifer system defines the altitude of water levels under pre-development conditions for aquifer unit A4, the lowermost group of aquifers in the sand aquifer system. Aquifer unit A4, consisting of Upper and Lower Cretaceous sands, is...
Quality of ground water used for public supply in Florida, 1983-84
G. A. Irwin, R.T. Kirkland, J. B. Pruitt
1985, Open-File Report 84-804
From October 1983 through March 1984, a chemical sampling reconnaissance was made of ground water used for public supply for 91 communities throughout Florida. Public supply wells present an excellent network for collecting baseline water-quality information on the quality of ground water prior to any treatment because they are located...
Water-quality data for 34 sites, April and June 1984, near the Y-12 Plant, the Oak Ridge Reservation, Tennessee
Pamela J. Pulliam
1985, Open-File Report 85-165
Water-quality data were collected at 34 sites in the vicinity of the Y-12 Plant, Oak Ridge, Tennessee, on April 12 and 13, 1984. Concentrations of dissolved major and trace constituents were determined; field determinations of specific conductance, pH temperature, alkalinity, and dissolved oxygen were made. Gross alpha and beta activity...
Potentiometric surfaces of November 1982 and declines in the potentiometric surfaces between the period prior to development and November 1982 for the coastal plain aquifers of South Carolina
Walter R. Aucott, Gary K. Speiran
1985, Water-Resources Investigations Report 84-4215
Characteristics of the Coastal Plains aquifer of South Carolina are being studied as a part of the Regional Aquifer Systems Analysis program of the U.S. Geological Survey. A framework has been developed to best represent the hydrology of the State by dividing the aquifers into a system of five aquifers....
Landsat multispectral scanner and Landsat thematic mapper images and interpretations of Hannapah and the Royston Hills, Nevada
T. L. Purdy, G. B. Bailey, John L. Dwyer
1985, Open-File Report 85-461
This Open-File Report consists of twenty-one 35-mm slides showing material that was presented at the Fourth Thematic Conference on Remote Sensing of the Environment held in San Francisco, California on April 1-4, 1985 (Purdy and others, 1985). The work was carried out in conjunction with the U.S. Geological Survey's Conterminous...
Mathematical model of the Tesuque aquifer system near Pojoaque, New Mexico
Glenn A. Hearne
1985, Water Supply Paper 2205
A three-dimensional digital model of ground-water flow was constructed to represent the dipping anisotropic beds of the Tesuque aquifer system underlying the Pojoaque River basin and vicinity, New Mexico. Simulations of steady-state conditions and historical ground-water withdrawals were consistent with observed data. The model was used to simulate the response...
Preliminary assessment of the ground-water resources of the alluvial aquifer, White River valley, Rio Blanco County, Colorado
W. P. Van Liew, M.L. Gesink
1985, Water-Resources Investigations Report 84-4307
A preliminary study of the alluvial aquifer in the White River Valley was conducted to assess aquifer extent and the occurrence , availability, and chemical quality of water in the aquifer. The aquifer in the study area underlies 35 square miles. Aquifer width ranges from 0.1 to 1.5 miles and...
Ground-water contamination in East Bay Township, Michigan
F. R. Twenter, T. R. Cummings, N.G. Grannemann
1985, Water-Resources Investigations Report 85-4064
Glacial deposits, as much as 360 feet thick, underlie the study area. The upper 29 to 118 feet, a sand and gravel unit, is the aquifer tapped for water by all wells in the area. This unit is underlain by impermeable clay that is at least 100 feet thick. Ground-water...
Quality of ground water in Monitor and Williams Townships, Bay County, Michigan
F. R. Twenter, T. R. Cummings
1985, Water-Resources Investigations Report 85-4110
Migration of mineralized water from abandoned subsurface coal mines in Monitor and Williams Townships was thought by many residents to have affected the quality of domestic ground-water supplies in the area. To investigate the possibility, wells were installed to obtain geologic data and water samples for chemical analysis; analysis also...
