Alan C. Jones
1978, Open-File Report 79-854
Using observations by Raitt and Shor, Hess (1964) noted that there was a correlation of compressional wave velocity in the mantle with seismic profile direction, suggesting that seismic anisotropy existed over a broad area of the Pacific basin. This paper describes a system developed and used to look for the...

The 2-year dry period 1976-77 was the most severe drought in northern California 's history, and the quantity and quality of all water-supply sources in the State were affected. This report contains special water-resources data collected by the Geological Survey during 1977. These data include: streamflow at 11 selected stations,...
FORTRAN programs for calculating nonlinear seismic ground response in two dimensions
W. B. Joyner
1978, Open-File Report 78-287
The programs described here were designed for calculating the nonlinear seismic response of a two-dimensional configuration of soil underlain by a semi-infinite elastic medium representing bedrock. There are two programs. One is for plane strain motions, that is, motions in the plane perpendicular to the long axis of the structure,...

Implementation plan for Bolivian Mineral Exploration Fund
Harold Kirkemo
1978, Open-File Report 79-597
Bolivia ranks second among world producers of tin and antimony, and first in bismuth production. Mineral exports in 1975 were valued at $314.2 million, nearly 60 percent of the value of all exports, and petroleum product exports totalled nearly $157 million, or 30 percent of the total. Tin accounted for...

Reconnaissance assessment of erosion and sedimentation in the Canada de los Alamos Basin, Los Angeles and Ventura counties, California
J. M. Knott
1978, Open-File Report 78-873
An assessment of present erosion and sedimentation conditions in the Canada de Los Alamos basin, Calif., was made to aid in estimating the impact of off-road-vehicle use on the sediment yield of the basin. Evaluations were made by reconnaissance techniques and by comparing the study area with other off-road-vehicle sites...

Evaluation of hydrogeologic aspects of proposed salinity control in Paradox Valley, Colorado
Leonard F. Konikow, M. S. Bedinger
1978, Open-File Report 78-27
The salt load in the Dolores River increases by about 200,000 tons per year where it crosses Paradox Valley, Colorado, because of the discharge of a sodium chloride brine from an underlying aquifer. A ground-water management program to nearly eliminate this major source of salt, which eventually enters the Colorado...
Hydrogeologic considerations for an interstate ground-water compact on the Madison aquifer, northern Great Plains
Leonard F. Konikow
1978, Open-File Report 78-138
The development of an interstate ground-water compact for the Madison aquifer in the Northern Great Plains may provide a framework to allocate equitably this large ground-water resource while avoiding possible future interstate legal conflicts. However, some technical problems will have to be resolved first. A compact designed to regulate or...

Since 1972 the U.S. Geological Survey has been conducting a series of field evaluation studies in southeastern New Mexico for the Waste Management Division of the Department of Energy (formerly U.S. Energy Research and Development Administration). On the basis of these studies, a tentative site for a nuclear waste repository/disposal...
Discrimination of hydrothermally altered rocks along the Battle Mountain-Eureka, Nevada, mineral belt using Landsat images

1978, Open-File Report 78-585
Landsat Multispectral Scanner (MSS) images of the northwestern part of the Battle Mountain-Eureki, Nevada mineral belt were evaluated for distinguishing hydrothermally altered rocks associated with porphyry copper and disseminated gold deposits. Detection of altered rocks from Landsat is based on the distinctive spectral reflectance of limonite present at coatings on...
