Saudi Arabian seismic deep-refraction profiles; final project report
J. H. Healy, W. D. Mooney, H. R. Blank, M. E. Gettings, W.M. Kohler, R.J. Lamson, L.E. Leone
1983, Open-File Report 83-390
In February 1978 a seismic deep-refraction profile was recorded by the U.S. Geological Survey along a 1000-km line across the Arabian Shield in western Saudi Arabia. The line begins in Mesozoic cover rocks near Riyadh on the Arabian Platform, leads southwesterly across three major Precambrian tectonic provinces, traverses Cenozoic rocks...
Explanation to accompany reconnaissance geologic map of the De Long Mountains A3, B3, and parts of A4, B4 quadrangles, Alaska
Charles F. Mayfield, S.M. Curtis, Inyo Ellersieck, I.L. Tailleur
1983, Open-File Report 83-183
This map is one of a series of three reconnaissance geologic maps of the southern De Long Mountains quadrangle (fig. 1). Because the geology in the three map areas is similar, a composite map explanation has been designed to facilitate their combined use and give a better perspective of the...
Water resources on the Pueblo of Laguna, west-central New Mexico
D. W. Risser, F. P. Lyford
1983, Water-Resources Investigations Report 83-4038
This study evaluates the quality and quantity of water available on the Pueblo of Laguna, New Mexico. Groundwater for public supply occurs in the valley fill along the Rio San Jose, in the Paguate and Encinal areas, and possibly in the northern part of the Sedillo Grant. The valley fill...
Spectral analysis of the 1976 aeromagnetic survey of Harrat Rahat, Kingdom of Saudi Arabia
H. Richard Blank, Hamdy S. Sadek
1983, Open-File Report 83-640
Harrat Rahat, an extensive plateau of Cenozoic mafic lava on the Precambrian shield of western Saudi Arabia, has been studied for its water resource and geothermal potential. In support of these investigations, the thickness of the lava sequence at more than 300 points was estimated by spectral analysis of low-level...
Instrumentation used for hydraulic testing of potential water-bearing formations at the Waste Isolation Pilot Plant site in southeastern New Mexico
J.A. Basler
1983, Open-File Report 83-144
Requirements for testing hydrologic test wells at the proposed Waste Isolation Pilot Plant near Carlsbad, New Mexico, necessitated the use of inflatable formation packers and pressure transducers. Observations during drilling and initial development indicated small formation yields which would require considerable test times by conventional open-casing methods. A pressure-monitoring system...
Records of selected wells and lithologic logs of test holes, Hendry County and adjacent areas, Florida
John E. Fish, Carmen R. Causaras, T.H. O’Donnell
1983, Open-File Report 83-134
To provide water-resource information for Hendry County, Florida , geologic test holes were drilled in the surficial aquifer, and an extensive inventory was compiled of wells in the surficial aquifer and deep artesian aquifers. This report provides: (1) records for 788 selected wells and test holes including location , construction,...
Hydrology of the Price River basin, Utah, with emphasis on selected coal-field areas
K.M. Waddell, J.E. Dodge, D.W. Darby, S.M. Theobald
1983, Open-File Report 83-208
Data obtained during a hydrologic study of the Price River basin, Utah, are used to describe seasonal variations of flow of springs, relation between ground water and surface water, hydraulic properties of the ground-water reservoir, ground-water recharge and discharge, flood characteristics of streams, mineralogic composition and depositional rates of sediments,...
Data for ground-water test hole near Nicolaus, Central Valley aquifer project, California
James J. French, R. W. Page, Gilbert L. Bertoldi
1983, Open-File Report 83-273
Preliminary data are provided for the third of seven test holes drilled as a part of the Central Valley Aquifer Project which is part of the National Regional Aquifer Systems Analysis Program. The test hole was drilled in the SW 1/4 NE 1/4 sec. 2, T.12N., R.3E., Sutter County, California,...
Crustal structure of southwestern Saudi Arabia
M. E. Gettings, H. R. Blank, W. D. Mooney, J. H. Healy
1983, Open-File Report 83-638
The southwestern Arabian Shield is composed of uplifted Proterozoic metamorphic and plutonic rocks. The Shield is bordered on the southwest by Cenozoic sedimentary and igneous rocks of the Red Sea paar and on the east by the Arabian Platform, an area of basin sedimentation throughout Phanerozoic time. The Shield appears...
Data supplement to: Quality of coal mine drainage to Washington, 1975-77
Louis A. Fuste, F. A. Packard, M. O. Fretwell, D.P. Garland
1983, Open-File Report 83-205
From December 1975 to September 1977 the U.S. Geological Survey studied coal mine drainage in western Washington to 1) characterize the water quality of drainage from abandoned mines in the 11 coal-bearing areas of the State; 2) examine the water quality effects on a stream receiving drainage from an abandoned...
