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...
Evaluation of Landsat multispectral scanner images for mapping altered rocks in the East Tintic Mountains, Utah
Lawrence C. Rowan, Michael J. Abrams
1979, Open-File Report 78-736
The East Tintic Mountains, Utah consist of folded and faulted Paleozoic sedimentary rocks, which are partly covered by Tertiary volcanic rocks. Clastic rocks dominate the lower one-third of the Paleozoic section, whereas carbonate rocks with subordinate amounts of shale and elastic rocks predominate in the remainder. Some of the rocks,...
Water resources data for Montana, water year 1978
Water Resources Division, U.S. Geological Survey
1979, Water Data Report MT-78-1
Water resources data for the 1978 water year for Montana consist of records of stage, discharge, and water quality of streams; stage, contents and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 211 gaging stations; stage only records for 1 lake...
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...
Susceptibility of the Memphis water supply to contamination from the pesticide waste-disposal site in northeastern Hardeman County, Tennessee
Donald Robert Rima
1979, Open-File Report 79-750
Public concern has been expressed over the possiblity that leachates from a pesticide waste-disposal site in northeastern Hardeman County, Tennessee, might eventually reach the Memphis area and endanger the city 's water supply. An examination of the possible pathways and means of transport of these contaminants reveals that, the Memphis...
Analytical and stratigraphic data on the upper phosphatic mudstone member of the Santa Margarita Formation at Newsome Canyon, southern Cuyama Valley, California
Albert Eugene Roberts
1979, Open-File Report 79-1466
A detailed stratigraphic and geochemical program was conducted in 1978 on the strata of the upper phosphatic mudstone member of the Santa Margarita Formation at Newsome Canyon, Santa Barbara County, California, (fig 1). This program was undertaken to determine the phosphate content of each stratigraphic unit in an area of...
The use of soil-gas helium concentrations for earthquake prediction: Studies of factors causing diurnal variation
G. Michael Reimer
1979, Open-File Report 79-1623
The diurnal variation in the soil-gas helium concentration was monitored at depths of 0.5-2 m. Barometric pressure, air temperature, wind speed, soil temperature, soil moisture, relative humidity, and precipitation were also monitored. The helium variation below a 1-m sampling depth usually did not exceed the analytical sensitivity limit of +10...
Soil-gas helium concentrations in the vicinity of a uranium deposit, Red Desert, Wyoming
G.M. Reimer, C.G. Bowles
1979, Open-File Report 79-975
A survey of the helium concentration in soil-gas was conducted in the Red Desert Area, Sweetwater County, Wyoming. The area studied is directly over a low-grade uranium deposit that may be suitable for recovery by in-situ leaching techniques. The area was sampled twice, once in December, 1977, and again in...
Thrust fault zones in the Allegheny Plateau of north-central Pennsylvania
Howard A. Pohn, Terri L. Purdy
1979, Open-File Report 79-1604
Field investigations in the Williamsport Valley identify lineaments found on Landsat III images, have shown the presence of six discrete fault zones that strike subparallel to the trend of the Appalachian folds. These zones range from 0.5 to 1.75 km in width and from at least 10 km to more...
Decollement in the southern Allegheny Plateau of Pennsylvania
Howard A. Pohn, Terri L. Purdy
1979, Open-File Report 79-1321
Recent field investigations in the Allegheny Plateau north of Williamsport, Pennsylvania have shown the presence of both southward dipping, low-angle thrust faults translated to the north and northward dipping back or antithectic thrusts translated to the south at the leading (north) edge of Barclay syncline. The presence of these thrusts,...
Petroleum source potential of rocks dredged from the continental slope in the eastern Gulf of Alaska
George Plafker, George Edwin Claypool
1979, Open-File Report 79-295
A bedrock dredging program by the R/V Sea Sounder in 1977 and 1978 along the continental slope in the eastern Gulf of Alaska revealed a previously unknown Eocene sedimentary sequence that includes argillaceous rocks with favorable petroleum source rock characteristics. Seven of 36 dredge hauls that sampled outcrop contain argillaceous...
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...
Elevations and discharges produced by a simulated flood wave on the lower Sabine River, Louisiana and Texas, caused by a theoretical dam failure
Braxtel L. Neely, Gloria J. Stiltner
1979, Open-File Report 79-678
The Toledo Bend Reservoir is located on the lower Sabine River between Louisiana and Texas. The objective of this study was to calculate the flood wave that would result from the theoretical failure of 25 percent of Toledo Bend Dam and route the wave downstream to Orange, Tex. Computations assumed...
Geology, petrology, and chemistry of the Leadville Dolomite: host for uranium at the Pitch Mine, Saguache County, Colorado
J. Thomas Nash
1979, Open-File Report 79-1566
Newly documented uranium ore in the Pitch Mine occurs chiefly in brecciated Mississippian Leadville Dolomite along the Chester reverse fault zone, and to a lesser extent in sandstone, siltstone, and carbonaceous shale of the Pennsylvanian Belden Formation and in Precambrian granitic rocks and schist. Uranium-mineralized zones are generally thicker, more...
