Water resources program of the U.S. Geological Survey related to agriculture in Louisiana
T.L. Huntzinger
1982, Open-File Report 82-554
Surveillance activities of the U.S. Geological Survey Louisiana District include long-term, hydrologic-data-collection sites that serve a current-purpose, management function and (or) that furnish a data base for interpretative studies. The proposed program for 1982 includes a network of 69 surface-water data sites (continuous gaging stations), 250 flood-data sites (crest-stage stations),...
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...
A preliminary evaluation of the nonfuel mineral potential of Somalia
W.R. Greenwood
1982, Open-File Report 82-788
Additional exploration in Somalia is warranted for a wide variety of metallic and nonmetallic deposits. In Precambrian rocks, deposit types favorable for exploration include: a banded iron formation; platinum-bearing mafic-ultramafic complexes; tin-bearing quartz veins; phosphorite; stratabound base-metal deposits; uranium associated with Precambrian(?) syenite; apatite, molybdenum, and alumina in alkalic rocks;...
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...
Origin of intraformational folds in the Jurassic Todilto Limestone, Ambrosia Lake uranium mining district, McKinley and Valencia counties, New Mexico
M. W. Green
1982, Open-File Report 82-69
The Todilto Limestone of Middle Jurassic age in the Ambrosia Lake uranium mining district of McKinley and Valencia Counties, New Mexico, is the host formation for numerous small- to medium-sized uranium deposits in joints, shear zones, and fractures within small- to large-scale intraformational folds. The folds probably were formed as...
Water Resources, California, water year 1981: Volume 2. Pacific Slope Basins from Arroyo Grande to Oregon State Line except Central Valley
Water Resources Division, U.S. Geological Survey
1982, Water Data Report CA-81-2
Water resources data in this volume for the 1981 water year consists of records of stage discharge, and water quality of streams and wells; stage, contents, and water quality in lakes and reservoirs; and water levels in wells. This report contains discharge records for 162 gaging stations; stage and contents...
Water resources data, West Virginia water year 1981, Appendix - coal areas and special projects
Water Resources Division, U.S. Geological Survey
1982, Water Data Report WV-81-A
The first section of this report contains data collected during the 1981 water year for the West Virginia Coal Hydrology monitoring project. Records consist of discharge and water-quality data collected at 246 sites in July, at 29 sites in August, and sediment data for 235 sites collected in July.The second...
Use of geophysical logs in recognizing depositional environments in the Tongue River Member of the Fort Union Formation, Powder River area, Wyoming and Montana
R. M. Flores, J.C. Toth, T.A. Moore
1982, Open-File Report 82-576
The environmental conditions under which rocks in the Paleocene Tongue River Member of the Fort Union Formation were deposited in the Powder River area, Wyoming and Montana, can be determined using geophysical logs with some limitations. It is widely recognized that gamma ray and density logs are useful in identifying...
Ground-water withdrawals and changes in water levels in the Houston District, Texas
R.K. Gabrysch
1982, Open-File Report 82-431
During 1975-79, total withdrawals of ground water in the Houston district decreased by 9.7 percent. This percentage represents a decrease from 505 million gallons per day (22.1 cubic meters per second) during 1975, to 456 million gallons per day (20.0 cubic meters per second) during 1979. The decrease resulted from...
Physical and hydrologic environments of the Mulberry coal reserves in eastern Kansas
J. F. Kenny, H.E. Bevans, A.M. Diaz
1982, Water-Resources Investigations Report 82-4074
Strippable reserves of Mulberry coal underlie an area of approximately 300 square miles of Miami, Linn, and Bourbon Counties of eastern Kansas. Although subject to State reclamation law, current and projected strip mining of this relatively thin coal seam could alter and hydrologic environment of the study area. Drained by...
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...
Methodology for stormwater runoff investigation, urban Leon County, Florida
M.A. Franklin
1982, Open-File Report 82-355
The U.S. Geological Survey in cooperation with Leon County is currently (1981) developing a lumped-parameter, rainfall-runoff model for the urban area of the county. Flood information from 16 sites is being collected and will be analyzed to define hydrologic relations useful for estimating magnitude and frequency of discharges in urban...
The lanthanides and yttrium in minerals of the apatite group; a review
Michael Fleischer, Z. S. Altschuler
1982, Open-File Report 82-783
More than 1000 analyses have been tabulated of the distribution of the lanthanides and yttrium in minerals of the apatite group, recalculated to atomic percentages. Average compositions have been calculated for apatites from 14 types of rocks. These show a progressive change of composition from apatites of granitic pegmatites, highest...
