Geology of the Khyber Pass, Khyber Agency, Pakistan
Karl W. Stauffer
1975, Open-File Report 75-272
The defile of the Khyber Pass is cut in the massive gray recrystallized Khyber Limestone whose thickness exceeds 3,000 feet. Although no fossils have been found in the immediate vicinity of the pass, assemblages collected at the end of the last century from 5 miles south of the pass, and...
Geology of the Gilgit-Hispar area, Gilgit Agency, Pakistan
Karl W. Stauffer
1975, Open-File Report 75-273
The Gilgit-Hispar area contains a large variety of igneous and metamorphic rocks, which have been grouped into seven general lithologic units, five composed largely of metamorphic rocks and two of intrusive rocks. The metamorphic units consist of probable correlatives of the Precambrian(?) Salkhala Series; the upper Paleozoic, slightly metamorphosed schists,...
Geochemical prospecting for copper and nickel in the Wulgai and Tor Tangi areas southeast of Hindubagh, Quetta Division, Pakistan
S. Anthony Stanin, M.A. Wahid, Shamsher Khan
1975, Open-File Report 75-163
Showings of magnetite, copper, and possible nickel mineralization in the Hindubagh chromite mining district are near Wulgai and Tor Tangi. Several hundred samples of clastic material from dry streambeds in these areas were sieved for the minus-80-mesh fraction and analyzed for copper using 2, 2'-biquinoline and for nickel using alpha-furildioxime....
Lithology and chemical analyses of core and cuttings from USGS drill hole near Gold Acres, Lander County, Nevada
Chester T. Wrucke
1975, Open-File Report 75-363
Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
A program for mass spectrometer control and data processing analyses in isotope geology; written in BASIC for an 8K Nova 1120 computer
J. S. Stacey, J. Hope
1975, Open-File Report 75-127
A system is described which uses a minicomputer to control a surface ionization mass spectrometer in the peak switching mode, with the object of computing isotopic abundance ratios of elements of geologic interest. The program uses the BASIC language and is sufficiently flexible to be used for multiblock analyses of...
Water resources data for Hawaii and other Pacific areas, water year 1974
Water Resources Division, U.S. Geological Survey
1975, Water Data Report HI-74-1
Water resources data for the 1974 water year for Hawaii and other Pacific areas including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface water, are given in this report. The records...
Chemical analysis of the waters of the Yellowstone National Park, Wyoming from 1965 to 1973
J. M. Thompson, T. S. Presser, R.B. Barnes, D.B. Bird
1975, Open-File Report 75-25
Analyses of Yellowstone Park thermal waters have been reported by many investigators extending back almost one hundred years. The first detailed analyses were reported by Gooch and Whitfield (1888). Allen and Day (1935) were second. White, Brannock, and Murata (1956) and Morey, Fournier, Hemley, and Rowe (1961) reported field analyses...
Hydrology of sand-and-gravel aquifer in central and southern Escambia County, Florida
Henry Trapp Jr.
1975, Open-File Report 74-218
The sand-and-gravel aquifer is the only fresh-water aquifer in the Pensacola area. Problems related to development of the aquifer include maximum safe yield, local contamination, local salt-water intrusion, corrosiveness of the water, areas of high iron concentration, and increasing nitrate concentration. The city of Pensacola is seeking hydrologic information, including...
Mineral deposits in western Saudi Arabia; a preliminary report
Ralph Jackson Roberts, William R. Greenwood, Ronald G. Worl, F. C. W. Dodge, Thor H. Kiilsgaard
1975, Open-File Report 75-654
Mineral deposits in Saudi Arabia include a variety of deposits which were formed in many geologic environments. These include magmatic and late magmatic deposits in igneous masses, contact metamorphic deposits along the margins of igneous bodies, and stratiform sulfide deposits and veins. Notable deposits of sedimentary origin include deposits of...
