Streamflow and sediment data collected at seven stream-gaging stations in the James River basin downstream from Forestburg, South Dakota, from October 1, 1982 to September 30, 1983
J.R. Little
1985, Open-File Report 85-156
A compilation of streamflow and suspended-sediment data collected from October 1, 1982, to September 30, 1983, at seven gaging stations in the James River basin downstream from Forestburg, South Dakota, is presented in tabular and graphic form. Three of the gaging stations are on the main stem and four are...
The Salma Caldera complex, northeastern Arabian Shield, Kingdom of Saudi Arabia
K.S. Kellogg
1985, Open-File Report 85-370
The upper Proterozoic Salma caldera is genetically part of an elongate alkali granitic massif, Jabal Salma. Comenditic ash-flow tuffs, the oldest recognized rocks of the caldera complex, were erupted during caldera collapse associated with the rapid evacuation of the upper, mildly peralkaline part of a zoned magma reservoir. Within the...
An example expert system for the interpretation of depositional environments
K. B. Krystinik
1985, Open-File Report 85-30
During 1983 the U.S. EPA requested the U.S. Geological Survey and the Missouri Department of Natural Resources to study the geology, water movement, and sediment characteristics of Sugar, Romaine, and Rock Creek basins in Jefferson County, Missouri. The information was needed because the EPA had confirmed the presence of dioxin...
Data processing programs for aerial gamma-ray data
Joseph S. Duval1
1985, Open-File Report 85-359
The U.S. Geological Survey (USGS) uses computer programs to process aerial gamma-ray data; some do editing and data manipulation to allow for corrections. Programs to convert flight-line data to latitude-longitude coordinates are included. Plotting programs include contour plotting, profile plots, and photographic raster plots....
Mineral potential of felsic plutonic rocks in the north-central Arabian Shield, Kingdom of Saudi Arabia
W. J. Moore
1985, Open-File Report 85-6
Fourteen plutons of Late Proterozoie age potentially favorable for rare-element mineralization have been identified in a geochemical and petrographic assessment of felsic plutonic rocks in the north-central Arabian Shield (lat 23°00'-25°00' N., long 40°00'-45°00' E.). The plutons are highly fractionated, leucocratic granitoids assigned to a major magmatic pulse that spanned...
Spirit Lake dam-failure flood routing assessment
D. L. Kresch
1985, Open-File Report 82-770
Potential clear-water floodflows resulting from uncontrolled breaching by Spirit Lake of a debris dam deposited by the May 18 , 1980, eruption of Mount St. Helens, Washington, were evaluated. U.S. Geological Survey dam-break model K-634 was utilized, first to compute clear-water flood hydrographs for various hypothetical breach scenarios, and then...
Quality of ground water used for public supply in Florida, 1983-84
G. A. Irwin, R.T. Kirkland, J. B. Pruitt
1985, Open-File Report 84-804
From October 1983 through March 1984, a chemical sampling reconnaissance was made of ground water used for public supply for 91 communities throughout Florida. Public supply wells present an excellent network for collecting baseline water-quality information on the quality of ground water prior to any treatment because they are located...
