Nonglacial origin for conglomerate beds in the Wajid Sandstone of Saudi Arabia
Donald G. Hadley, Dwight L. Schmidt
1974, Open-File Report 74-21
Conglomerate beds containing sparse boulders in the upper part of the Wajid Sandstone of Permian or older(?) age have been interpreted as Gondwana glacial deposits (Helal, 1965). These beds, exposed in the Bani Khatmah area near the southeastern edge of the Arabian Shield of Saudi Arabia, contain normally graded polymictic...

A tabulation of K-Ar, Rb-Sr and Pb-alpha ages obtained for materials within the United States (including Alaska and Hawaii) during the years 1969 through 1971
Richard F. Marvin
1974, Open-File Report 74-1070
This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States from 1969 through 1971. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-α ages but is probably 98% complete. Many of the radiometric ages published...

Richard F. Marvin
1974, Open-File Report 74-1068
This tabulation of ages has been made as a convenience to anyone desiring a quick reference to ages published in the United States from 1956 through 1964. This tabulation does not include all published K-Ar, Rb-Sr, or Pb-a ages, but is probably 98 percent complete. Many of the radiometric ages...
Summary of hydrologic conditions and effects of Walt Disney World development in the Reedy Creek Improvement District, 1966-73
Arthur L. Putnam
1974, Open-File Report 74-339
The Reedy Creek Improvement District (hereinafter called the RCID) is an area of about 43 square miles (111. square kilometres) in southwest Orange and northwest Osceola Counties. Before development of Walt Disney World began (mid-1967), all of this tract of land was scrubby flatlands and swamp. Walt Disney World facilities...
Posssible extension of mineral belts, northern part of Coeur d'Alene district, Idaho
Garland Bayard Gott, Joseph Moses Botbol
1974, Open-File Report 74-67
The ore deposits in the northern part of the Coeur d'Alene district are located within rocks of the Belt Supergroup that have been intruded by Cretaceous quartz monzonites. Lead-zinc-silver replacement veins constitute most of the deposits. The geometry of the district has been modified by post-ore faulting along the Osburn,...
Long term flow of the Truckee River in California and Nevada
Howard Frederick Matthai
1974, Open-File Report 74-213
The Office of the Solicitor, Department of the Interior, requested the Geological Survey to evaluate the reliability of streamflow records in the Truckee River basin and to determine the long-term average annual runoff.The reliability of streamflow records was evaluated by comparisons between pairs of records at six locations along the...
GEOPAC
Richard H. Godson
1974, Open-File Report 74-1039
GEOPAC .consists of a series of subroutines to primarily process potential-field geophysical data but other types of data can also be used with the program. The package contains routines to reduce, store, process and display information in two-dimensional or three-dimensional form. Input and output formats are standardized and temporary disk...
A computer system for the storage and retrieval of gravity data, Kingdom of Saudi Arabia
Richard H. Godson, Gordon H. Andreasen
1974, Open-File Report 74-1040
A computer system has been developed for the systematic storage and retrieval of gravity data. All pertinent facts relating to gravity station measurements and computed Bouguer values may be retrieved either by project name or by geographical coordinates. Features of the system include visual display in the form of printer...
Floodflow characteristics of Fourche Creek at Interstate Highway 430, in southwest Little Rock, Arkansas
R.C. Gilstrap, J.N. Sullavan
1974, Open-File Report 74-343
The Arkansas State Highway Department is constructing Interstate Highway 430 (1-430) across Fourche Creek in southwest Little Rock. The Highway Department requested the U.S. Geological Survey to determine the elevation, the discharge, and the frequency of the flood of April 21, 1974, and the elevation, the discharge, and the backwater...
Effects of local geology on ground motion in the San Francisco Bay region, California: A continued study
James F. Gibbs, Roger D. Borcherdt
1974, Open-File Report 74-222
Measurements of ground motion generated by nuclear explosions in Nevada have been completed for 99 locations in the San Francisco Bay region, California. The seismograms, Fourier amplitude spectra, spectral amplification curves for the signal, and the Fourier amplitude spectra of the seismic noise are presented for 60 locations. Analog amplifications,...
Selected U.S. Bureau of Mines reports on Alaska indexed by quadrangle
Edward H. Cobb
1974, Open-File Report 74-52
Most U.S. Bureau of Mines reports on the geology and mineral resources of Alaska that were published or placed in open files through April 30, 1974, are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). References to reports that deal with...
Geochemical survey of the western coal regions; first annual progress report, July 1974
Jon J. Connor, Ronald R. Tidball, James A. Erdman, Richard J. Ebens, John R. Keith, Barbara M. Anderson
1974, Open-File Report 74-250
National energy needs have precipitated an increased interest in the development of a large coal-based electric power industry in the western United States. This anticipated development has, in turn, spawned a great deal of interest in the environmental impact consequent upon the mining and utilization of these coal supplies. Numerous...
