Albuquerque Basin seismic network
Lawrence H. Jaksha, Jerry Locke, J.B. Thompson, Alvin Garcia
1977, Open-File Report 77-865
The U.S. Geological Survey has recently completed the installation of a seismic network around the Albuquerque Basin in New Mexico. The network consists of two seismometer arrays, a thirteen-station array monitoring an area of approximately 28,000 km 2 and an eight-element array monitoring the area immediately adjacent to the Albuquerque...
The use of Galerkin finite-element methods to solve mass-transport equations
David B. Grove
1977, Water-Resources Investigations Report 77-49
The partial differential equation that describes the transport and reaction of chemical solutes in porous media was solved using the Galerkin finite-element technique. These finite elements were superimposed over finite-difference cells used to solve the flow equation. Both convection and flow due to hydraulic dispersion were considered. Linear and Hermite...
Techniques for estimating magnitude and frequency of floods in Minnesota
Lowell C. Guetzkow
1977, Water-Resources Investigations Report 77-31
 Estimating relations have been developed to provide engineers and designers with improved techniques for defining flow-frequency characteristics to satisfy hydraulic planning and design requirements. The magnitude and frequency of floods up to the 100-year recurrence interval can be determined for most streams in Minnesota by methods presented. By multiple regression...

Computer program for the calculation of grain size statistics by the method of moments
Michael B. Sawyer
1977, Open-File Report 77-580
A computer program is presented for a Hewlett-Packard Model 9830A desk-top calculator (1) which calculates statistics using weight or point count data from a grain-size analysis. The program uses the method of moments in contrast to the more commonly used but less inclusive graphic method of Folk and Ward (1957). The...
Reconnaissance geologic study of the Vazante zinc district, Minas Gerais, Brazil
Charles H. Thorman, Samir Nahass
1977, Open-File Report 77-630
The Vazante district, Minas Gerais, 130 km south of Paracatu, produces nearly all of Brazil's zinc metal. The district is situated on the western side of the Late Precambrian Bambul basin and along the eastern and leading edge of the north-trending Brazilian orogenic belt (ca. 600-500 m.y. old) that borders...
Socioeconomic impacts of outer continental shelf oil and gas development; a bibliography
Malka L. Pattison
1977, Circular 761
The bibliography lists reports which are concerned primarily with the socioeconomic impacts of OCS oil and gas development or which, although not primarily concerned with such impacts, include sections that contain significant discussion of them. Several of the cited reports do not address socioeconomic issues directly, but have been included...
