Diffusimetry (diffusion constant estimation) on sediment cores by resistivity probe
Frank T. Manheim, Lee S. Waterman
1974, Initial reports of the Deep Sea Drilling Project (22) 663-670
Measurement of formation factor (ratio of rock resistivity to interstitial water resistivity) from sediment cores provides an indirect measurment of the tortuosity of the fluid channels in the sediments. From these measurements one can estimate the diffusion coefficient of the sediment with depth. The F (formation factor) values for Indian...
Buried Triassic basin in the central Savannah River area, South Carolina and Georgia
L. Wendell Marine, George E. Siple
1974, GSA Bulletin (85) 311-320
A basin filled with Triassic red beds, located on the South Carolina–Georgia line ∼32 km southeast of Augusta, Georgia, is buried beneath ∼350 m of Coastal Plain sediments. An extensive aeromagnetic survey, seismic refraction and reflection surveys, and geophysical logs and samples from three wells define the extent and character...

Lakes of Oregon, Volume 2: Benton, Lincoln, and Polk Counties
M.V. Shulters
1974, Report
An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never...

1974, Hydrologic Unit 22
This map and accompanying table show Hydrologic Units that are basically hydrographic in nature. The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Information on Water Data (1966-72). The previous U.S. Geological Survey Catalog-Indexing System was by map number...

Water-management studies of a stream-aquifer system, Arkansas River Valley, Colorado
O. James Taylor, Richard R. Luckey
1974, Groundwater (12) 22-38
A mathematical model was developed and used to simulate the stream-aquifer system in the Arkansas River valley in southeastern Colorado, from Pueblo to the Colorado-Kansas State line. The model simulates the interrelations among ground water and surface water including reservoirs, losses, and transmountain diversions, utilizing various water-distribution rules. The model...
Determination of selenium in water
M. Lansford, E. M. McPherson, Marvin J. Fishman
1974, Atomic Absorption Newsletter (13) 103-105
The determination of selenium by hydride generation atomic absorption spectrophotometry using zinc is widely used. Very little is mentioned, however, on possible interferences. In an attempt to use this technique for the determination of selenium in natural waters, interferences were found. The most serious interference occurred when arsenic was present....
Life history of the spottail shiner (Notropis hudsonius) in southeastern Lake Michigan, the Kalamazoo River, and western Lake Erie
LaRue Wells, Robert House
1974, Research Report 78
In southeastern Lake Michigan spottail shiners in samples ranged from ages 0 to V, but most were in age groups I-IV. In the Kalamazoo River (a tributary of southeastern Lake Michigan) age group II was commonest in the catches, and no fish older than age IV were sampled. In western...
Invertebrate macrobenthos of Lake Oahe, 1968-69
William E. Jones, James H. Selgeby
1974, Technical Paper 73
The benthos in Lake Oahe, as determined from about 450 bottom samples collected during the open water season in 1968 and 1969, was dominated by oligochaetes and chironomids; Caenis (Ephemeroptera) and Chaoborus (Diptera) were occasionally abundant. Total benthos was estimated at 3,600 organisms/mA? with an ash-free dry weight of about...

Urban water planning, development, and management are many sectored, costly efforts, subject to a multitude of controls and demands including those imposed by nature. One primary concern in development is for providing a dependable and safe water supply. In spite of a bountiful natural availability, the process of satisfying consumer...

Teleseismic studies indicate existence of deep magma chamber below Yellowstone National Park
H. M. Iyer
1974, Earthquake Information Bulletin (USGS) (6) 3-7
The secrets of Yellowstone National Park's spectacular geysers and other hot water and steam phenomena are being explored by the U.S Geological Survey with the aid of distant earthquakes (teleseisms). For some time geologists have known that the remarkable array of steam and hot water displays, for which the park...
Argillization by descending acid at Steamboat Springs, Nevada
Robert Schoen, Donald E. White, J.J. Hemley
1974, Clays and Clay Minerals (22) 1-22
Steamboat Springs, Nevada, an area of present-day hot springs, clearly illustrates the genetic dependence of some kaolin deposits on hot-spring activity. Andesite, granodiorite and arkosic sediments are locally altered at the land surface to siliceous residues consisting of primary quartz and anatase, plus opal from primary silicates. These siliceous residues...
Spectrophotometric determination of molybdenum in rocks with thiocyanate
E.G. Lillie, L. P. Greenland
1974, Analytica Chimica Acta (69) 313-320
A rapid procedure for the determination of microgram amounts of molybdenum in rocks is described. After acid decomposition, molybdenum is extracted from a hydrochloric acid solution into xylene with tributyl phosphate. After back-extraction with water, molybdenum is extracted as the α-benzoinoximate into chloroform, stripped into...
