Hydrologic data for floods of July 1978 in Southeast Minnesota and Southwest Wisconsin
V.J. Latkovich
1979, Open-File Report 79-1166
Intense storms of July 1978 caused floods of historical significance in southeast Minnesota and southwest Wisconsin. Local, State, and Federal officials need data and information to evaluate, coordinate, and manage programs concerned with floods and flood losses. Because of a need to document stream discharges, elevations, and sediment concentrations, current-meter...
Accessory opaque oxides from hybrid granitoid rocks of the southern Snake Range, Nevada
Donald E. Lee, Richard E. Van Loenen
1979, Open-File Report 79-1608
Analytical data are presented for 12 magnetite and 6 ilmenite samples recovered from hybrid granitoid rocks of the southern Snake Range, Nevada. The magnetites are unusual for their very low contents of TiO2 and for their similarity of composition over a range of petrologic types. The ilmenites are somewhat unusual...
Ground-water-quality data from the northern Powder River Basin, southeastern Montana
Roger W. Lee
1979, Open-File Report 79-1331
Water-quality data collected during 1973-77 for hydrologic studies in the northern Powder River basin of southeastern Montana provide a data base for shallow ground water. The 665 water samples collected were analyzed for major cations and anions. Of the samples, 516 were from wells and 149 were from springs. About...
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...
Chemical analysis and geochemical associations in Devonian black shale core samples from Martin County, Kentucky; Carroll and Washington counties, Ohio; Wise County, Virginia; and Overton County, Tennessee
Joel S. Leventhal
1979, Open-File Report 79-1503
Core samples from Devonian shales from five localities in the Appalachian Basin have been analyzed for major, minor, and trace constituents. The contents of major elements are rather similar; however, the minor constituents, organic C, S, PO4, and CO3, show variations by a factor of 10. Trace elements Mo, Ni,...
Organic matter and sandstone-type uranium deposits: a primer
Joel S. Leventhal
1979, Open-File Report 79-1310
Organic material is intimately associated with sandstone-type uranium deposits in the western United States.. This report gives details of the types of organic matter and their possible role in producing a uranium deposit. These steps include mobilization of uranium from igneous rocks, transportation from the surface, concentration by organic matter,...
Uranium and organic matters: use of pyrolysis-gas chromatography, carbon, hydrogen, and uranium contents to characterize the organic matter from sandstone-type deposits
Joel S. Leventhal
1979, Open-File Report 79-942
Organic matter seems to play an important role in the genesis of uranium deposits in sandstones in the western United States. Organic materials associated with ore from the Texas coastal plain, Tertiary basins of Wyoming, Grants mineral belt of New Mexico, and the Uravan mineral belt of Utah and Colorado...
Alaskan papers and abstracts published in American Association of Petroleum Geologists Bulletin, 1950-1978, indexed by quadrangle
Edward Huntington Cobb
1979, Open-File Report 79-1475
This open—file report lists all papers and abstracts on the geology and mineral resources of Alaska published in the American Association of Petroleum Geologists Bulletin from 1950 through 1978. They are listed by the quadrangles (scale 1:250,000) into which Alaska has been subdivided for topographic mapping (p. 2).Reports that deal...
Artificial-recharge investigation near Aurora, Nebraska: 2-year progress report
William F. Lichtler, David I. Stannard, Edwin Kouma
1979, Open-File Report 79-1492
This report presents the results of the first 2 years of a 4-year investigation of potential for artificial recharge and recharge methods that might be used to mitigate excessive aquifer depletion in Nebraska.A Quaternary sand-and-gravel aquifer near Aurora, Nebr., was recharged by injecting water through a well at a rate...
Preliminary report on Tertiary volcanism and uranium mineralization in the Thomas Range and northern Drum Mountains, Juab County, Utah
David Allen Lindsey
1979, Open-File Report 79-1076
The Thomas Range and northern Drum Mountains have a history of volcanism, faulting, and mineralization that began about 42 m.y. ago. Volcanic activity and mineralization in the area can be divided into three stages according to the time-related occurrence of rock types, trace element associations, and chemical nature of mineralization....
Organic carbon content of Devonian shale sequence sampled in drill cuttings from eighteen wells in western Pennsylvania
George Edwin Claypool, Allan W. Stone
1979, Open-File Report 79-1665
This report contains results of organic carbon analyses performed by Rinehart Laboratories, Inc., Arvada, Colorado, under contract to the U.S. Geological Survey. The analytical method employs chemical (chromic acid) oxidation of an acid solution containing the rock residue. The detailed analytical specifications are contained in the Rinehart proposal in response...
Relation between proposed developments of water resources and seepage from the All-American Canal, eastern Imperial Valley, California
Omar J. Loeltz, S. A. Leake
1979, Open-File Report 79-744
A two-layer digital model designed for this study indicated that sealing of the Coachella branch of the All-American Canal would cause an eventual increase in seepage from the All-American Canal of about 15,000 acre-feet annually. Sealing of both the Coachella Canal and the segment of the All-American Canal between Pilot...
