Vincent J. Flanigan, Hamdy Sadek
1983, Open-File Report 83-367
Parts of four airborne electromagnetic (AEM) anomalies were selected for study in order to determine the cause of high conductivity of Precambrian rocks underlying extensive areas in the southern Wadi Bidah district, Kingdom of Saudi Arabia. In the Assifar area, which contains an ancient mine or prospect having the same...
Precision gravity networks at Lassen Peak and Mount Shasta, California
Robert C. Jachens, Daniel Dzurisin, W.P. Elder, R. W. Saltus
1983, Open-File Report 83-192
Reoccupiable precision gravity networks for the purpose of monitoring volcanic activity were established in the vicinity of Lassen Peak and Mt. Shasta. Base-line measurements were made during the summer of 1981, nearly coincident in time with other base-line geodetic measurements. The gravity surveys yielded gravity values at network stations relative...

A preliminary evaluation of stream sediment sampling for the detection of cobalt mineralization in the Bou Azzer District, Morocco
M. P. Foose
1983, Open-File Report 83-383
Analyses of 28 stream sediment samples collected in the Bou Azzer district, Morocco, show that this sampling technique may be useful in locating the cobalt arsenide mineralization that exists in this area. The absence of exceptionally high values of cobalt and arsenic, the nearly lognormal distribution of cobalt values, and...
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,...

Geophysical methods for locating abandoned wells
Frank C. Frischknecht, L. Muth, R. Grette, T. Buckley, B. Kornegay
1983, Open-File Report 83-702
A preliminary study of the feasibility of using geophysical exploration methods to locate abandoned wells containing steel casing indicated that magnetic methods promise to be effective and that some electrical techniques might be useful as auxiliary methods. Ground magnetic measurements made in the vicinity of several known cased wells yielded...
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,...
Geochemical characteristics of the Church Rock 1 and 1 East uranium deposits, Grants uranium region, New Mexico

1983, Open-File Report 83-194
In the Church Rock 1 and 1 East mines, Grants uranium region (GUR), New Mexico, uranium orebodies occur within three sandstone units in the upper part of the Westwater Canyon Member of the late Jurassic Morrison Formation. Geochemical analyses reveal that organic carbon contents in ore samples from all three...

1983, Open-File Report 83-85
Magnetotellurics is a geophysical technique which was developed by Cagnaird (1953) and Tikhonov (1950) and later refined by other scientists worldwide. The technique is a method of electromagnetic sounding of the Earth and is based upon the skin depth effect in conductive media. The electric and magnetic fields arising from...
