Ground-water levels and quality data for Georgia, 1978
J.S. Clarke, W.G. Hester, M. P. O’Byrne
1979, Open-File Report 79-1290
Mean water levels in wells across Georgia were from 0.25 foot higher to 11.4 feet lower in 1978 than in 1977, and in some areas were the lowest on record. Water levels in the principal artesian aquifer underwent a long-term decline during the period 1969-78. In some areas water levels...
Rock Analysis Storage System (RASS), Saudi Arabia; an introduction to the system and sample submittal manual, 1978
Lamont O. Wilch, L.D. North
1979, Open-File Report 79-591
The U.S. Geological Survey Saudi Arabian Mission has the responsibility for implementing a computer-based file known as the Rock Analysis Storage System (RASS), which is principally a geochemical data bank or library. Geologic parameters are necessarily provided for, but are far from comprehensive; nevertheless, nine years of operation in the...
The Jabal Ishmas-Wadi Tathlith gold belt, Kingdom of Saudi Arabia
Ronald G. Worl
1979, Open-File Report 79-1519
The Jabal Ishmas-Wadi Tathlith gold belt is a north-south zone of numerous ancient gold mines in the southeastern Precambrian shield of Saudi Arabia, extending along long 43?30'E. between lat 18?N. and 21?30'N., a distance of about 390 km. The gold belt coincides with a major zone of faulting, shearing, and...
Trace-element distribution around a South Texas roll-type uranium deposit
Charles S. Spirakis
1979, Open-File Report 79-1375
The distribution of trace elements around a south Texas roll-type uranium deposit was examined using semiquantitative emission spectroscopic analytical data complemented by some quantitative data. The results suggest that of the 50 elements analyzed, only beryllium and possibly vanadium are enriched in the altered rock on the updip side of...
Palladium, platinum, and rhodium concentrations in mafic and ultramafic rocks from the Kizildag and Guleman areas, Turkey, and the Faryab and Esfandagheh-Abdasht areas, Iran
Norman J. Page, Tandogan Engin, Joseph Haffty
1979, Open-File Report 79-840
The Kizildag and Guleman areas, Turkey, and the Faryab and Esfandagheh-Abdasht areas, Iran, have produced chromite from ophiolite complexes consisting of harzburgite tectonite, dunite tectonite containing chromitite, pyroxenite, wehrlite, and gabbro. Forty-six samples from these complexes were analyzed in order to investigate the possibility of platinum-group metals being present that...
Ground-water data for Michigan, 1977
G.C. Huffman
1979, Open-File Report 79-332
The purpose of this report is to make available the 1977 records of water levels and related data for the principal aquifers of the State. These records and data provide a means for evaluating available ground-water supplies. Long- term records serve as a framework to which short-term records may be...
Low-flow characteristics of streams in the Pecatonica-Sugar River basin, Wisconsin
D.A. Stedfast
1979, Open-File Report 79-1274-Pecatonica River, Sugar River
The purpose of this report is to describe low-flow characteristics of streams in the Pecatonica-Sugar River basin, Wisconsin, where streamflow data have been collected, and to present equations for estimating low-flow characteristics at ungaged sites. Low-flow characteristics were estimated for 11 gaging stations, 25 low-flow partial-record stations, and 207 miscellaneous sites...
Preliminary catalog of aftershocks of the Guatemala earthquake of February 4, 1976, from the area between Guatemala City and Lake Atitlan
R.A. White, David H. Harlow
1979, Open-File Report 79-864
A six-station seismic network, about 140 km in diameter, has been operated just west of Guatemala City since March 1975, as part of a cooperative project between the U.S. Geological Survey and the Institute Nacional de Sismologia, Vulcanologia, Meteorologia e Hidrologia (INSIVUMEH), of Guatemala. The purpose of this project was...
The brightness of lights on Earth at night, digitally recorded by DMSP satellite
Thomas A. Croft
1979, Open-File Report 80-167
The U.S. Air Force has operated its Defense Meteorological Satellite Program (DMSP) for nearly a decade, and film images from the system have been openly available since 1973. Films are well suited for the study of weather, and users of such films have derived much useful data. For many potential...
Benthic invertebrates, periphyton, and bottom material and their trace-metal concentrations in Salmon Creek basin, Clark County, Washington
Amy C. White, Stuart W. McKenzie
1979, Open-File Report 79-978
In 1978, data were collected for identification and quantification of benthic invertebrates, periphyton, and bottom material and their trace-metals concentrations from three sites in Salmon Creek basin, Wash. Metal analyses included arsenic, cadmium, chromium, copper, lead, zinc, selenium, and mercury. Physical data collected included water temperature, dissolved oxygen, pH, discharge,...
A proposed ground water quality monitoring network for Idaho
R.L. Whitehead, D. J. Parliman
1979, Open-File Report 79-1477
A ground water quality monitoring network is proposed for Idaho. The network comprises 565 sites, 8 of which will require construction of new wells. Frequencies of sampling at the different sites are assigned at quarterly, semiannual, annual, and 5 years. Selected characteristics of the water will be monitored by both...
January 1979 water levels, and data related to water-level changes, western and south-central Kansas
Marilyn E. Pabst
1979, Open-File Report 79-925
This report contains hydrologic data on water-level measurements in observation wells in western and south-central Kansas. The measurements were made in mid-winter, mostly in January, when pumping was minimal and water levels had recovered from the effects of pumping during the previous irrigation season. This report also provides basic hydrologic...
