The environment of south-central Tunisia as observed on Landsat scene 206/036
M. J. Grolier, P.A. Schultejann
1982, Open-File Report 82-130
One Landsat image in south-central Tunisia was analyzed to demonstrate the application of remote-sensing technology to regional development. A preliminary analysis included I) major landscape features; 2) gypsum-encrusted soils; and 3) phosphate-bearing beds exposed in the Gafsa mining district. The products specifically used for this report include: 1) A false-color...
Silver Plume Granite; possible source of uranium in sandstone uranium deposits, Tallahassee Creek and High Park areas, Fremont and Teller counties, Colorado
F. A. Hills, K. A. Dickinson
1982, Open-File Report 82-404
Anomalously high concentrations of thorium and of the light rare earth elements lanthanum and cerium suggest that the actinides and light lanthanides were enriched to an abnormal degree by the magmatic processes that formed the Proterozoic Y Silver Plume Granite in areas adjoining Tallahassee Creek and High Park. However, no...
A heat-pulse flowmeter for measuring minimal discharge rates in boreholes
A.E. Hess
1982, Open-File Report 82-699
The U.S. Geological Survey has tested a borehole-configured heat-pulse flowmeter which has good low-velocity flow-measuring sensitivity. The flowmeter was tested in the laboratory in 51-, 102-, and 152-millimeter-diameter columns using water velocities ranging from 0.35 to 250 millimeters per second. The heat-pulse flowmeter also was tested in a 15-meter-deep granite...
Small-stream flood investigations in Minnesota, October 1958 to September 1980
Kurt T. Gunard, C.J. Smith
1982, Open-File Report 82-433
An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 200 square miles, placing particular emphasis on those...
Thermodynamic properties of selected uranium compounds and aqueous species at 298.15 K and 1 bar and at higher temperatures; preliminary models for the origin of coffinite deposits
B. S. Hemingway
1982, Open-File Report 82-619
Thermodynamic values for 110 uranium-bearing phases and 28 aqueous uranium solution species (298.15 K and l bar) are tabulated based upon evaluated experimental data (largely from calorimetric experiments) and estimated values. Molar volume data are given for most of the solid phases. Thermodynamic values for 16 uranium-bearing phases are presented...
Hydrologic investigations and data-collection network in strippable coal-resource areas in northwestern New Mexico
H.R. Hejl
1982, Open-File Report 82-358
This report presents hydrologic investigations and data collections conducted by the U.S. Geological Survey in the strippable coal areas of northwestern New Mexico. Streamflow, ground-water, and quality-of-water data were collected to provide information about baseline or prevailing hydrologic conditions. A network of hydrologic data-collection sites in the strippable coal areas...
Supplement to the New Mexico three-dimensional model
Glenn A. Hearne
1982, Open-File Report 82-857
The computer program documented in Open-File Report 80-421 has continued to evolve in response to needs. By January 1981, changes included the following: (1) treatment of head-dependent boundaries and specified-flow boundaries and (2) code which executes on the CRAY-1 computer. This report provides instructions for compiling and executing the computer...
Water-resources studies in Utah, July 1, 1981 to June 30, 1982
1982, Open-File Report 82-643
This report summarizes the progress on water-resources studies in Utah by the U.S. Geological Survey during the period July 1, 1981, to June 30, 1982. Much of the work was done in cooperation with the State of Utah or local agencies. Additional supporting funds were transferred from other Federal agencies...
Some silicified strophomenacean brachiopods from the Ordovician of Kentucky, with comments on the genus Pionomena
J.K. Pope
1982, Professional Paper 1066-L
Eight species of silicified strophomenid brachiopods from Ordovician rocks of Kentucky are described in this report. Seven species are strophomenaceans, including six from the Middle Ordovician and one, Leptaena kentuckiana n. sp., from the Upper Ordovician. Pionomena recens Neuman from the Middle Ordovician is referred to the Davidsoniacea. Three of...
