Reconnaissance geology and geochronology of the Precambrian of the Granite Mountains, Wyoming
Zell E. Peterman, Robert A. Hildreth
1978, Professional Paper 1055
The Precambrian of the western part of the Granite Mountains, Wyoming, contains a metamorphic complex of gneisses, schists, and amphibolites that were derived through amphibolite-grade metamorphism from a sedimentary-volcanic sequence perhaps similar to that exposed in the southeastern Wind River Mountains. Whole-rock Rb-Sr dating places the time of metamorphism at...
High-flow frequencies for selected streams in Oklahoma

1978, Open-File Report 78-161
Streamflow records are analyzed statistically to determine high-flow characteristics of selected streams in Oklahoma. Tables are included which show the 2-, 5-, 10-, 25-, 50-, and 100-year high-flow frequencies for durations of 1, 3, 7, 30, 90, and 365 days. The log-Pearson Type III frequency distribution was used in the...

Major Precambrian and minor Tertiary intrusive rocks northeast of Steamboat Springs in the Park Range between 40°30' and 40°45' N. lat. are described and compared with related rocks elsewhere in Colorado and Wyoming. The Precambrian intrusives were emplaced in a sequence of high-grade interlayered felsic gneisses, amphibolites, and pelitic schists...
The hydrothermal system of Long Valley Caldera, California
M.L. Sorey, Robert Edward Lewis, F. H. Olmsted
1978, Professional Paper 1044-A
Long Valley caldera, an elliptical depression covering 450 km 2 on the eastern front of the Sierra Nevada in east-central California, contains a hot-water convection system with numerous hot springs and measured and estimated aquifer temperatures at depths of 180?C to 280?C. In this study we have synthesized the results...

William F. Isherwood, Donald Plouff
1978, Open-File Report 78-298
Gravity observations were made at 292 locations in the Coso Hot Springs area, California (figs. 1 and 2). The field work was completed during June 1976 by William F. Isherwood and Jerry H. Hassemer using LaCoste-Romberg Gravity Meters G-131 and G-159. The purpose of the gravity survey is to provide...

Thomas H. Yorke, William J. Herb
1978, Professional Paper 1003
Land use, precipitation, streamflow, and sediment discharge data were collected from nine small drainage basins in Montgomery County, Maryland, to evaluate runoff and sediment response to sediment-control practices in areas undergoing urban development. Drainage basins ranged in size from 0.35 to 21.1 sq mi and land use ranged from rural...
Historic ground failures in Northern California triggered by earthquakes
T. Leslie Youd, Seena N. Hoose
1978, Professional Paper 993
A major source of earthquake-related damage and casualties in northern California has been ground failures generated by the seismic shaking, including landslides, lateral spreads, ground settlement, and surface cracks. The historical record shows that, except for offshore shocks, the geographic area affected and the quantity and general severity of ground...
Field determination of vertical permeability to air in the unsaturated zone
Edwin P. Weeks
1978, Professional Paper 1051
The vertical permeability to air of layered materials in the unsaturated zone may be determined from air pressure data obtained at depth during a period when air pressure is changing at land surface. Such data may be obtained by monitoring barometric pressure with a microbarograph or surveying altimeter and simultaneously...
Hydraulic geometry of river cross sections; theory of minimum variance
Garnett P. Williams
1978, Professional Paper 1029
This study deals with the rates at which mean velocity, mean depth, and water-surface width increase with water discharge at a cross section on an alluvial stream. Such relations often follow power laws, the exponents in which are called hydraulic exponents. The Langbein (1964) minimum-variance theory is examined in regard...

Selected water-level records for Oklahoma, 1975-1977
Robert L. Goemaat, Dannie E. Spiser
1978, Open-File Report 78-721
A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for...
A literature review of interaction of oxidized uranium species and uranium complexes with soluble organic matter
Joan K. Jennings, J.S. Leventhal
1978, Open-File Report 78-179
Organic material is commonly found associated with uranium ores in sandstone-type deposits. This review of the literature summarizes the classes and separations of naturally occurring organic material but the emphasis is on soluble organic species. The main class of materials of interest is humic substances which are high-molecular-weight complex molecules...
