Vegetation and climates of the last 45,000 years in the vicinity of the Nevada Test Site, south-central Nevada
W. G. Spaulding
1983, Open-File Report 83-535
Paleoclimatic reconstructions for the Nevada Test Site, spanning the last 45,000 years, are based on plant macrofossil assemblages from radiocarbonated packrat (Neotoma spp) middens from south-central Nevada. The temperature regime during the Wisconsin glacial age, from before about 45,000 years ago until about 12,000 years ago, was characterized by lower...

Data compilation of benthic invertebrates from tributary streams in Yampa and North Platte River Basins, northwestern Colorado
L. J. Britton
1983, Open-File Report 83-140
Benthic invertebrates were collected from Trout Creek, Fish Creek, and the Williams Fork (tributaries of the Yampa River in Routt and Moffat Counties), and Little Grizzly and Grizzly Creeks (tributaries of the North Platte River in Jackson County). Stream-sampling sites were upstream and downstream from potential, existing, or historical coal-mining...
Electrical and magnetic properties of rock and soil
J. H. Scott
1983, Open-File Report 83-915
Field and laboratory measurements have been made to determine the electrical conductivity, dielectric constant, and magnetic permeability of rock and soil in areas of interest in studies of electromagnetic pulse propagation. Conductivity is determined by making field measurements of apparent resisitivity at very low frequencies (0-20 cps), and interpreting the...

1983, Open-File Report 83-141
This report presents data collected to determine the hydraulic characteristics of rocks penetrated in test well USW H-1. The well is one of a series of test wells drilled in and near the southwestern part of the Nevada Test Site, Nye County, Nevada, in a program conducted on behalf of...
Distribution and quantitative assessment of world crude oil reserves and resources
Charles D. Masters, David H. Root, William D. Dietzman
1983, Open-File Report 83-728
World Demonstrated Reserves of crude oil are approximately 723 billion barrels of oil (BBO). Cumulative production is 445 BBO and annual production is 20 BBO. Demonstrated Reserves of crude-oil have declined over the past 10 years consistent with discoveries lagging production over the same period. The assessment of Undiscovered Resources...
Geophysical investigations in the Dhahar-Al Hajrah region, Wadi Malahah Quadrangle, southwestern Saudi Arabia
H. R. Blank
1983, Open-File Report 83-778
Crone electromagnetic, self-potential, and induced polarization surveys were conducted in the Dhahar-Al Hajrah region, southwestern Saudi Arabia, in support of geological and geochemical exploration for volcanogenic sulfide deposits. Although a previous, airborne electromagnetic survey found no anomalies in the vicinity of the ancient mines in the region, surface indications of...

Hydrologic data from the Johnson Brook phosphorus loading study, Kennebec County, Maine
Thomas J. Maloney, David R. Dominie, William J. Nichols
1983, Open-File Report 83-143
Streamflow, water quality, and precipitation data collected during the 1980 and 1981 water years are reported. The purpose was to document changes in total phosphorus loads resulting from a change in agricultural waste management practices in the Johnson Brook watershed in Maine. Streamflow data include mean-daily discharges for the period...
Paleocene pycnodont fishes from Jabal Umm Himar, Harrat Hadan area, Kingdom of Saudi Arabia
Gary T. Madden
1983, Open-File Report 83-453
Three species of Pycnodus, a genus of extinct holostean fishes, have been identified from the Paleocene of Jabal Umm Himar, Harrat Hadan area, south-central Saudi Arabia, an area that was contiguous with Africa during the Early Tertiary. One of the species is larger than any species identified from the Early...
Mastritherium (Artiodactyla, Anthracotheriidae) from Wadi Sabya, southwestern Saudi Arabia; an earliest Miocene age for continental rift-valley volcanic deposits of the Red Sea margin
Gary T. Madden, Dwight Lyman Schmidt, Frank C. Whitmore
1983, Open-File Report 83-488
A lower jaw fragment with its last molar (M/3) from the Baid formation in Wadi Sabya, southwestern Saudi Arabia, represents the first recorded occurrence in the Arabian Peninsula of an anthracotheriid artiodactyl (hippo-like, even-toed ungulate). This fossil is identified as a primitive species of Masritherium, a North and East African...

Analyses of native water, bottom material, elutriate samples, and dredged material from selected southern Louisiana waterways and selected areas in the Gulf of Mexico, 1979-81
Dee L. Lurry
1983, Open-File Report 82-690
The U.S. Geological Survey was requested by the U.S. Army Corps of Engineers, New Orleans District, to provide water-quality data to evaluate environmental effects of dredging activities in selected reaches of the Calcasieu River in southwestern Louisiana. Samples were collected from the upper and lower Calcasieu River between January 1980...

Helmuth Wedow
1983, Open-File Report 83-352
The empirical model for sediment-associated, stratiform, exhalative, massive-sulfide deposits presented by D. Large in 1979 and 1980 has been redesigned to permit its use in a computer-assisted search for exploration-target areas in Devonian rocks of the Appalachian region using attribute-coincidence mapping (ACM). Some 36 gridded-data maps and selected maps derived...

Landsat analysis for uranium exploration in Northeast Turkey
Keenan Lee
1983, Open-File Report 83-99
No uranium deposits are known in the Trabzon, Turkey region, and consequently, exploration criteria have not been defined. Nonetheless, by analogy with uranium deposits studied elsewhere, exploration guides are suggested to include dense concentrations of linear features, lineaments -- especially with northwest trend, acidic plutonic rocks, and alteration indicated by...
