Upper Cretaceous tectonic activity on lineaments in western South Dakota
George W. Shurr
1979, Open-File Report 79-1374
Lineaments mapped on satellite images in western South Dakota define a geometry of basement blocks, and paleotectonic activity on these lineament-bound blocks is recorded in sedimentary rocks. Mapping on seven Landsat images in an area of about 100,000 km2 reveals that lineaments are best developed along azimuths of N. 60°...
Uranium potential of the Big John Caldera, Beaver County, Utah

1979, Open-File Report 79-527
The Big John caldera is a small subsidence structure in the Marysvale volcanic field, high along the western flank of the Tushar Mountains in west-central Utah (fig. 1). This caldera formed 22 m.y. ago in response to ash-flow eruptions of the Delano Peak Tuff Member of the Bullion Canyon Volcanics....

Principal facts for borehole gravity stations in wells DC-3, DC-5, and DC-7 at the Hanford Site, Washington, and in well RSH No. 1 on Rattlesnake Hills, Washington
S. L. Robbins, R.J. Martinez, D.L. Smith
1979, Open-File Report 79-849
Borehole gravity surveys were carried out in four wells in the State of Washington by the U.S. Geological Survey (U.S.G.S.) in September and October of 1978 using the U.S.G.S. - LaCoste and Romberg borehole gravity meter G-95 (BHGM) (McCulloh and others, 1967a; McCulloh and others, 1967b). The primary objective of...
Geologic evaluation of major Landsat lineaments in Nevada and their relationship to ore districts
Lawrence C. Rowan, Pamela Heald Wetlaufer
1979, Open-File Report 79-544
Analysis of diverse geologic, geophysical, and geochemical data shows that eight major lineament systems delineated in Landsat images of Nevada are morphological and tonal expressions of substantially broader structural zones. Southern Nevada is dominated by the 175 km-wide northwest-trending Walker Lane, a 150 km-wide zone of east-trending lineament systems consisting...

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...

Physical characteristics of suspended sediments, South Texas Continental Shelf
Gerald L. Shideler
1979, Open-File Report 79-362
This report presents the results of a three-year study of suspended sediments within the South Texas OCS region. The investigations were a part of the environmental studies of the South Texas Outer Continental shelf sponsored by the Bureau of Land Management. The physical properties of the suspended particulate system studied...
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 possible role of sulfate-reduction kinetics in the formation of hydrothermal uranium deposits
Charles S. Spirakis
1979, Open-File Report 79-673
As a sulfate-bearing, hydrothermal solution cools to less than about 200°C, kinetic factors prevent sulfate from entering into oxidation-reduction reactions. Consequently, the reducing effect of H2S (and other reduced species) is not balanced with the oxidizing effect of SO4= to the same extent as at higher temperatures. The result is...

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,...
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

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...
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...
Sediment discharge and channel change in the North Fork Teton River, 1977-78, Fremont and Madison counties, Idaho
Rhea P. Williams
1979, Open-File Report 79-1335
The Teton Dam failure flood of June 5, 1976, severely disrupted the geomorphic character of North Fork Teton River in Idaho. Extensive channel restoration was required to contain expected normal spring flows. Six principal sites were established on the 17-mile reach of the river to study sediment transport and channel...
