Water-resources investigations in North Dakota; fiscal year 1983
Nancy K. Lankford, Luverne L. Albright
1983, Open-File Report 83-220
All ongoing water resources projects in North Dakota in fiscal year 1983, are listed. The report was prepared to inform interested federal, State, and local agencies and private individuals of the activities of the Water Resources Division in the State. Information on each project includes objectives, approach, progress in 1982,...
Trace-element geochemistry of postorogenic granites from the northeastern Arabian Shield, Kingdom of Saudi Arabia
John S. Stuckless, R. J. Knight, G. VanTrump, J. R. Budahn
1983, Open-File Report 83-287
Concentrations determined for all of the trace elements included in this study of postorogenic granites from the northeastern Arabian Shield are best described by log-normal distributions. The trace elements are divided into two groups: (1) compatible lithophile and siderophile elements (strontium, cobalt, scandium, manganese, europium, and titanium) and (2) incompatible...
A seismic study of Yucca Mountain and vicinity, southern Nevada; data report and preliminary results
L.R. Hoffman, W. D. Mooney
1983, Open-File Report 83-588
From 1980 to 1982, the U.S. Geological Survey conducted seismic refraction studies at the Nevada Test Site to aid in an investigation of the regional crustal structure at a possible nuclear waste repository site near Yucca Mountain. Two regionally distributed deployments and one north-south deployment recorded nuclear events. First arrival...
Report of the U.S. Geological Survey's analytical evaluation program; standard reference water samples M-82 (major constituents), T-83 (trace constituents), N-8 (nutrients), and P-2 (precipitation snowmelt)
V.J. Janzer
1983, Open-File Report 83-864
The U.S. Geological Survey began an interlaboratory testing program of reference water samples in 1962. Principal purposes of the program are to provide a means for participating water laboratories to: (1) identify analytical problem areas; (2) ascertain the accuracy and precision of common water analyses and analytical methods and; (3)...
Geoelectric structure of the Gila-San Francisco Wilderness Area, Graham and Greenlee Counties, Arizona, from audio-magnetotelluric data
D. P. Klein, M. J. Baer
1983, Open-File Report 83-815
Electromagnetic induction data using distant field sources, mostly of natural origin, in the frequency range of 4.5-27,000 Hz are analyzed to depict the geoelectric structure in an area of volcanic-rock cover located in southeastern Arizona between the Morenci and Safford porphyry copper deposits. The data for each station consist of...
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Allegheny National Forest, Warren County, Pennsylvania
N. L. Hickling, Stanley P. Schweinfurth, Betty M. Adrian
1983, Open-File Report 83-5
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Warren County, Pennsylvania, was made by members of the U.S. Geological Survey (USGS) to test for indistinct or unexposed mineral deposits that might be recognized by geochemical halos. Analyses using semiquantitative emission spectrography and atomic absorption for...
Data for ground-water studies of the San Juan Basin, New Mexico (1982-83)
R.L. Klausing, G. E. Welder
1983, Open-File Report 84-135
Ground-water data that can be used for futher hydrologic studies in the San Juan structural basin of New Mexico are reported. Descriptions and a location map of 64 observation wells, a list of water levels measured in the observation wells, water-level hydrographs of 32 wells, 15 partial chemical analyses of...
Geohydrology and water resources of the Papago Farms-Great Plain area, Papago Indian Reservation, Arizona, and the upper Rio Sonoyta area, Sonora, Mexico
K.J. Hollett
1983, Open-File Report 83-774
The Papago Farms-Great Plain and upper Rio Sonoyta study area includes about 490 square miles in south-central Arizona and north-central Sonora, Mexico. In the study area 23,700 acre-feet of ground water from the basin-fill deposits was used to irrigate more than 5,000 acres in 1981. Surface water is not a...
Geochemical evaluation of felsic plutonic rocks in the eastern and southeastern Arabian Shield, Kingdom of Saudi Arabia
E. A. Du Bray, James E. Elliott, D. B. Stoeser
1983, Open-File Report 83-369
In a geochemical evaluation of the eastern and southeastern Arabian Shield, which included collection of 696 rock samples and 694 pan concentrate samples, a province of tin-anomalous granitoid plutons was defined. Pan concentrates collected in and around these plutons were enriched in tin and tungsten relative to the concentrate population....
