A water-quality assessment of the Jordan Creek watershed, Warren County, Indiana
Mark A. Ayers
1975, Open-File Report 75-323
A water-quality assessment of the Jordan Creek watershed was made September 24 and 25, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents and specific conductance values. Streamwaters contained less than 0.26 milligram per litre dissolved nitrate (as N), 0.03 milligram...
Sources of emergency water supplies in San Mateo County, California
P.R. Wood
1975, Open-File Report 75-43
San Mateo County has several densely populated urban areas that get most of their water supplies from surface-water sources that could by damaged by a major earthquake or other general disaster. In the event of such a disaster, limited supplies of potable water may be obtained from selected wells, springs,...
Preliminary report on the use of LANDSAT-1 (ERTS-1) reflectance data in locating alteration zones associated with uranium mineralization near Cameron, Arizona
Charles S. Spirakis, Christopher D. Condit
1975, Open-File Report 75-416
LANDSAT-I (ERTS-I) multispectral reflectance data were used to enhance the detection of alteration around uranium deposits near Cameron, Ariz. The technique involved stretching and ratioing computer-enhanced data from which electronic noise and atmospheric haze had been removed. Using present techniques, the work proves that LANDSAT-I data are useful in detecting...
Analytical data for geologic units in Missouri and parts of Kansas, Oklahoma and Arkansas
Josephine G. Boerngen, George Van Trump, Richard J. Ebens
1975, Open-File Report 75-137
This report lists the geochemical data collected during the course of a reconnaissance study of compositional variation in the bedrock and surficial gelogic untis exposed in Missouri and adjoining parts of Kansas, Oklahoma, and Arkansas.  The primar object of the study was to assess scale-related components of geochemical variance with...
A review of recently active faults in Taiwan
Manuel G. Bonilla
1975, Open-File Report 75-41
Six faults associated with five large earthquakes produced surface displacements ranging from 1 to 3 m in the period 1906 through 1951. Four of the ruptures occurred in the western coastal plain and foothills, and two occurred in the Longitudinal Valley of eastern Taiwan. Maps are included showing the locations...
Prediction of maximum earthquake intensities for the San Francisco Bay region
Roger D. Borcherdt, James F. Gibbs
1975, Open-File Report 75-180
The intensity data for the California earthquake of April 18, 1906, are strongly dependent on distance from the zone of surface faulting and the geological character of the ground. Considering only those sites (approximately one square city block in size) for which there is good evidence for the degree of...
Reconnaissance study of sediment transport by selected streams in the Yakima Indian Reservation, Washington, 1974 water year
Philip Richard Boucher
1975, Open-File Report 75-67
This was a reconnaissance study for information on suspended-sediment concentrations and basin yields at 21 sites on selected streams in the Yakima Indian Reservation in Washington, and two sites on nearby streams. Suspended-sediment yields were generally low relative to those indicated by data for other streams on southeastern Washington, the...
A summary of relative ages of lunar nearside and farside plains
Joseph M. Boyce, Arthur L. Dial, Laurence A. Soderblom
1975, Open-File Report 75-141
This report contains a summary of the moon-wide distribution of relative ages of lunar plains units determined with Apollo and Lunar Orbiter photographs. Relative ages are expressed as the largest diameter of craters (DL, meters) in a mappable unit that are eroded to a slope of 1° by the net...
