Phase 3 geophysical studies in the Wadi Bidah District, Kingdom of Saudi Arabia
V. J. Flanigan, Hamdy Sadek, C. W. Smith
1982, Open-File Report 82-597
Detailed geophysical measurements have been made in the Rabathan area, Wadi Bidah district, Kingdom of Saudi Arabia, at the site of diamond drill holes RAB-1, -2, and -3; these measurements suggest that the causative source for the anomalous EM (electromagnetic) and SP (self-potential) responses is probably highly conductive zones of...
Full-time equivalency tracking system
Stephen Klesert
1982, Open-File Report 82-556
To help meet the goals of the Surface-Mining Control and Reclamation Act of 1977, the U.S. Geological Survey is assessing the physical, chemical, and biological characteristics of surface water within the coal-mining region of southwestern Indiana. This report discussed benthic-invertebrate and periphytic-algal communities in streams draining homogeneous agricultural, forested, active/reclaimed-mine,...
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...
Water resources of the Gig Harbor Peninsula and adjacent areas, Washington
B. W. Drost
1982, Open-File Report 81-1021
The study area is a remnant of a glacial-drift plain nearly surrounded by marine embayments. A water-resources appraisal was made because the area is experiencing rapid population growth. Additional ground water is available for use in the study area. At least 11 cubic feet per second, five times the 1978...
Water resources of the Black Hand Sandstone Member of the Cuyahoga Formation aquifers of Mississippian age in southeastern Ohio
S.E. Norris, G.C. Mayer
1982, Open-File Report 82-170
The Black Hand Sandstone Member of the Cuyahoga Formation and associated acquifers of Mississippian age, including the Allensville Conglomerate Member of the Logan Formation, (both members of the local usage) were investigated in a 1 ,500-square-mile area in southeastern Ohio. These aquifers are the chief sources of water beneath the...
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...
Reconnaissance geochemical survey of the At Taif-Al Bahah region, southern Hijaz, Kingdom of Saudi Arabia
E. A. Du Bray, J. L. Doebrich
1982, Open-File Report 82-790
Pan concentrates were prepared from 265 wadi sediment samples collected during a geochemical reconnaissance conducted between At Taif and Al Bahah to further assess previously identified tungsten anomalies and to locate additional mineralized rock. The samples were analyzed by semiquantitative spectrographic methods for 30 elements, and tungsten was determined by...
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...
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...
Report of the annual yield of the Arkansas River basin for the Arkansas River Basin Compact, Arkansas-Oklahoma, 1981 water year
G.L. Ducret Jr.
1982, Open-File Report 82-168
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, 1980, are presented. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given. Monthly, maximum, minimum, and mean discharges are shown for the 14 streamflow...
