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....

Edward A. du Bray
1983, Open-File Report 83-370
Sixteen well-defined geochemical anomalies associated with felsic plutons and (or) muscovite-bearing plutons of Proterozoic age have been identified in the eastern and southeastern Arabian Shield. The majority of these plutons are highly evolved, granitophile-element-enriched muscovite-bearing granites that are weakly peraluminous. A followup study of the mineral potential of these plutons included...

A study was made, in cooperation with the Division of Water Resources, Kansas State Board of Agriculture, to determine geohydrologic conditions in an area comprising nearly 850,000 acres along the Arkansas River valley in Kearny and Finney Counties, southwestern Kansas. The Arkansas River meanders atop and interacts hydraulically with the...

Application of Gauss algorithm and Monte Carlo simulation to the identification of aquifer parameters
Timothy J. Durbin
1983, Open-File Report 81-688
The Gauss optimization technique can be used to identify the parameters of a model of a groundwater system for which the parameter identification problem is formulated as a least squares comparison between the response of the prototype and the response of the model. Unavoidable uncertainty in the true stress on...

Floods of April 1983 in southern Mississippi and southeastern Louisiana
Darrell D. Carlson, Gary D. Firda
1983, Open-File Report 83-685
Extreme flooding occurred in April 1983 in southern Mississippi and southeastern Louisiana. The floods resulted from a near-stationary cold front, which moved slowly across Louisiana and Mississippi. Flood heights and discharges of many streams exceeded previously known maximums of record, and for many the recurrence interval of peak discharge exceeded...
Ground-water levels in Arkansas, spring 1983
Joe Edds
1983, Open-File Report 83-268
About 640 ground-water level measurements were made in observation wells in Arkansas in the spring of 1981. In addition , the report contains potentiometric-surface maps and well hydrographs relating to the alluvial aquifer and the Sparta Sand , the most important aquifers with respect to ground-water availability and use in...
Landslide investigations, southern Cianjur Regency, West Java Province, Indonesia; a progress report
John R. Ege
1983, Open-File Report 83-597
Two landslide-monitoring sites have been established for a minimum 2-year investigation near the villages of Pasirpari and Cibacang in southern Cianjur Regency, West Java, Indonesia. Surveyed-in lines will measure amounts of surface movement and tilt, borings that produced exploratory cores now serve as slip-surface detectors and open-pipe piezometers, and rain...
Mitigation of hazards from future lahars from Mount Merapi in the Krasak River channel near Yogyakarta, central Java
John R. Ege, Sutikno
1983, Open-File Report 83-596
Procedures for reducing hazards from future lahars and debris flows in the Krasak River channel near Yogyakarta, Central Java, Indonesia, include (1) determining the history of the location, size, and effects of previous lahars and debris flows, and (2) decreasing flow velocities. The first may be accomplished by geologic field...
Peralkaline and peraluminous granites and related mineral deposits of the Arabian Shield, Kingdom of Saudi Arabia
James E. Elliott
1983, Open-File Report 83-389
In the Precambrian Arabian Shield, granitoid plutonic rocks are widespread and range in age from 800 to 550 Ma old; but the mineral-resource potential associated with these plutonic rocks is restricted mainly to the younger, postorogenic granites. Two granite types of current economic interest are zirconium- niobium-enriched per alkaline granites...
Explosion-induced stress changes estimated from vibrating-wire stressmeter measurements near the Mighty Epic event, Nevada Test Site
William L. Ellis, J.D. Kibler
1983, Open-File Report 83-642
Explosion-induced compressive stress increases near an underground nuclear explosion are believed to contribute significantly to the containment of high-pressure gases within the explosion-produced cavity. These induced compressive stresses are predicted by computer calculations, but have never been adequately confirmed by field measurements, owing primarily to the unique difficulties of obtaining...
Hydraulic-fracturing measurmements in two boreholes near the Spent Fuel Test-Climax, Climax Stock, Nevada Test Site
William L. Ellis
1983, Open-File Report 83-406
Hydraulic-fracturing measurements are used to infer the magnitude of the least principal stress in the vicinity of the Spent Fuel Test-Climax, located in the Climax stock at the Nevada Test Site. The measurements, made at various depths in two exploratory boreholes, suggest that the local stress field is not uniform....
Preliminary assessment of in-situ geomechanical characteristics in drill hole USW G-1, Yucca Mountain, Nevada

Observations made during drilling and subsequent testing of the USW G-1 drill hole, Yucca Mountain, Nevada, provide qualitative insights into the in- situ geomechanical characteristics of the layered tuff units penetrated by the hole. Substantial drilling-fluid losses, and the occurrence of drilling-induced fracturing, are understandable in terms of the low,...
