Preliminary assessment of in-situ geomechanical characteristics in drill hole USW G-1, Yucca Mountain, Nevada
William L. Ellis, Henri S. Swolfs
1983, Open-File Report 83-401
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,...
Continuous seismic-reflection survey defining shallow sedimentary layers in the Charlotte Harbor and Venice areas, southwest Florida
R. M. Wolansky, F.P. Haeni, R.E. Sylvester
1983, Water-Resources Investigations Report 82-57
A continuous marine seismic-reflection survey system was used to define the configuration of shallow sedimentary layers underlying the Charlotte Harbor and Venice areas, southwest Florida. Seismic profiling was conducted over a distance of about 57 miles of Charlotte Harbor, the Peace and Myakka Rivers, and the Intracoastal Waterway near Venice...
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...
Data from the surface-water hydrologic investigations of the Hay Creek Study Area, Montana, and the West Branch Antelope Creek Study Area, North Dakota, October 1976 through April 1982
Douglas G. Emerson, Steven W. Norbeck, Kelvin L. Boespflug
1983, Open-File Report 83-136
Data are provided for the Hay Creek study area near Wibaux, Mont., and the West Branch Antelope Creek study area near Beulah, N. Dak. The report contains data on the following: Air temperature, relative humidity, wind direction, wind run, solar radiation, precipitation, soil temperature, snowpack temperature, snowpack density and water...
Sedimentology of the lower part of the upper Triassic Chinle Formation and its relationship to uranium deposits, White Canyon area, southeastern Utah
Russell F. Dubiel
1983, Open-File Report 83-459
Closely spaced measured stratigraphic sections of the lower part of the Late Triassic Chinle Formation in the White Canyon area of southeastern Utah depict a fluvial-deltaic-lacustrine depositional sequence that hosts uranium deposits in basal fluvial sandstones. The basal Shinarump Member consists of predominantly trough-crossbedded, coarse-grained sandstone and minor gray, carbonaceous...
Estimating generalized flood skew coefficients for Michigan
H.M. Croskey, D. J. Holtschlag
1983, Water-Resources Investigations Report 83-4194
Current estimates of station skew indicate that estimates of generalized skew obtained from the skew map of the United States prepared by the U.S. Water Resources Council have a -0.27 bias for Michigan. Station skew was recomputed using currently recommended statistical procedures of the Water Resources Council, and available data...
Quality-assurance data for routine water analysis in the laboratories of the US Geological Survey for water-year 1982
Dale B. Peart, Nancy Thomas
1983, Water-Resources Investigations Report 83-4264
The U.S. Geological Survey maintains a quality-assurance program based on the analysis of reference samples for its two water-analysis laboratories located in Atlanta, Georgia, and Denver, Colorado. Reference samples containing inorganic constituents are prepared at the U.S. Geological Survey 's Ocala , Florida, office and disguised as routine samples, and...
Geophysical investigations of the Umm ar Rummf copper prospect, Al Qunfudhah Quadrangle, Kingdom of Saudi Arabia
Hamdy S. Sadek, H. Richard Blank
1983, Open-File Report 83-298
The Umm ar Rummf copper prospect, located about 30 km east of Al Qunfudhah, Kingdom of Saudi Arabia, consists of zones of malachite disseminations and fracture fillings in outcrops of north-trending impure quartzite of the Bahah group. Systematic Crone electromagnetic and self-potential surveys indicate that weakly conductive tabular bodies having...
Use of flumes in measuring discharge
F. A. Kilpatrick, V.R. Schneider
1983, Techniques of Water-Resources Investigations 03-A14
Flumes for measuring discharge are usually of two general groups-critical-flow flumes and supercritical-flow flumes. In this chapter, the underlying design principles for each group are discussed; the most commonly used flumes are described and their discharge ratings presented. There is also discussion of considerations in choosing and fitting the appropriate...
Garnet peridotites from Williams kimberlites, north-central Montana, U.S.A
B.C. Hearn, E. S. McGee
1983, Open-File Report 83-172
Two Williams kimberlites, 250x350m and 37x390m, in the eastern part of a swarm of 30 middle Eocene alnoitic diatremes in north-central Montana, USA, contain xenoliths of garnet-bearing lherzolites, harzburgites and dunites, in addition to spinel peridotites and upper and lower crustal amphibolites and granulites. Colluvial purple, red, and pink garnets...
Sediment transport in the Tanana River near Fairbanks, Alaska, 1980-81
R.L. Burrows, P.E. Harrold
1983, Water-Resources Investigations Report 83-4064
Suspended-sediment- and bedload-transport rates for the Tanana River near Fairbanks, Alaska, can be related to water discharge. Annual sediment loads can be computed using these relations. For a site at Fairbanks, the annual loads in 1980 were 22.0 million metric tons of suspended sediment and 272,000 metric tons of bedload;...
Ground water in the Redding Basin, Shasta and Tehama counties, California
M.J. Pierce
1983, Water-Resources Investigations Report 83-4052
An appraisal of ground-water conditions in the Redding Basin was made by the U.S. Geological Survey and the California Department of Water Resources during 1979 and 1980. The basin covers about 510 square miles in the northern part of the Central Valley of California. Ground water in the basin is...
