Geochemical survey of the Chattahoochee Roadless Area, Towns, Union, and White counties, Georgia
Robert P. Koeppen, Arthur E. Nelson
1989, Miscellaneous Field Studies Map 1502-B
Th U.S. Geological Survey made a reconnaissance geochemical survey of the Chattahoochee Roadless Area (fig. 1) to search for unexposed mineral deposits which might be recognized by a geochemical signature in the abundance or distribution patterns of trace elements. As part of a regional geochemical reconnaissance, M/ Hurst (University of...
Geochemical survey of the Blood Mountain Roadless Area, Union and Lumpkin counties, Georgia
Robert P. Koeppen, Arthur E. Nelson
1989, Miscellaneous Field Studies Map 1503-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Blood Mountain Roadless Area to search for unexposed mineral deposits which might be recognized by a geochemical signature in the abundance of distribution patterns of trace elements. Forty five fine-grained stream-sediment samples and 45 panned-concentrate samples were collected...
Vertical surface displacements along a part of the Newport-Inglewood zone of folds and faults, Los Angeles and Orange Counties, California
Robert O. Castle, Jane M. Buchanan-Banks
1989, Miscellaneous Field Studies Map 2088
During the past half century, the onshore section of the Newport- Inglewood zone of folds and faults between the Dominguez oil field and Corona del Mar (fig. 1) has been repeatedly leveled to geodetic standards. These essentially fortuitous surveys are unrelated to either the tectonic framework or the urbanization...
Sedimentation survey of Lago Dos Bocas, Puerto Rico, June 1985
Ferdinand Quinones, Frank Melendez, Carlos Bonnet
1989, Open-File Report 86-241
A survey of the sedimentation of Dos Bocas reservoir, in central Puerto Rico, was conducted during July 1985. The survey showed that the capacity of the reservoir has declined from 30,420 acre-ft in 1942 to about 19,620 acre-ft. Sediment is accumulating in the reservoir at an average rate of about...
XAP, a program for deconvolution and analysis of complex X-ray spectra
James E. Quick, Abdul Malik Haleby
1989, Open-File Report 89-338
The X-ray analysis program (XAP) is a spectral-deconvolution program written in BASIC and specifically designed to analyze complex spectra produced by energy-dispersive X-ray analytical systems (EDS). XAP compensates for spectrometer drift, utilizes digital filtering to remove background from spectra, and solves for element abundances by least-squares, multiple-regression analysis. Rather than...
Hydraulic characteristics of the New River in the New River Gorge National River, West Virginia
J.B. Wiley, David H. Appel
1989, Open-File Report 89-243
Traveltime, dispersion, water-surface and streambed profiles, and cross-section data were collected for use in application of flow and solute-transport models to the New River in the New River Gorge National River, West Virginia. Dye clouds subjected to increasing and decreasing flow rates (unsteady flow) showed that increasing flows shorten the...
Analytical solutions for one-, two-, and three-dimensional solute transport in ground-water systems with uniform flow
Eliezer J. Wexler
1989, Open-File Report 89-56
Analytical solutions to the advective-dispersive solute-transport equation are useful in predicting the fate of solutes in ground water. Analytical solutions compiled from available literature or derived by the author are presented in this report for a variety of boundary condition types and solute-source configurations in one-, two-, and three-dimensional systems...
