Analytical results for 249 water samples from the Mount Belknap caldera and Deer Trail Mountain-Alunite Ridge areas and vicinity, southwestern Utah
Robert E. Tucker, J. B. McHugh, W. H. Ficklin, J. M. Motooka, D. J. Preston, W. R. Miller
1983, Open-File Report 83-738
Two hundred and forty-nine water samples were collected from small first-order streams, springs, and mine drainages from the Mount Belknap caldera and Deer Trail Mountain-Alunite Ridge areas and vicinity in southwestern Utah. The samples were collected during three hydrogeochemical surveys in 1978, 1979, and 1981. The water samples were analyzed...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: January 1983
John B. Townshend, J.E. Papp, E.A. Sauter, T.K. Cunningham, L.Y. Torrence
1983, Open-File Report 83-300-A
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Sources and mechanisms of recharge for ground water in the west-central Amargosa Desert, Nevada– A geochemical interpretation
H.C. Claassen
1983, Open-File Report 83-542
Ground water in the west-central Amargosa Desert, Nevada, was recharged primarily by overland flow of snowmelt in or near the present-day stream channels, rather than by subsurface flow from highland recharge areas to the north. Geochemical arguments, including reaction mechanisms, are used to support these findings. Carbon-, hydrogen-, and oxygen-isotope...
Preliminary lithologic, geotechnical, and geophysical data from drill hole CW-81-2, Chuitna West coal field, Cook Inlet region, Alaska
Jack K. Odum, Cynthia A. Gardner, Lynn A. Yehle, Henry R. Schmoll, Larry L. Dearborn
1983, Open-File Report 83-78
The drilling and logging activity described in this report was undertaken in July 1981, as part of the Energy Lands program of the U.S. Geological Survey. The general objectives of the project of which this work is a part are to provide an understanding of the nature, location, and extent...
Preliminary results of spectral induced polarization measurements, Wadi Bidah District, Kingdom of Saudi Arabia
Bruce D. Smith, C. L. Tippens, V. J. Flanigan, Hamdy Sadek
1983, Open-File Report 83-612
Laboratory spectral induced polarization (SIP) measurements on 29 carbonaceous schist samples from the Wadi Bidah district show that most are associated with very long polarization decays or, equivalently, large time constants. In contrast, measurements on two massive sulfide samples indicate shorter polarization decays or smaller time constants. This difference in...
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...
