Flume studies of the transport of pebbles and cobbles on a sand bed
Robert K. Fahnestock, W.L. Haushild
1962, Geological Society of America Bulletin (73) 1431-1436
During experiments on sediment transport and resistance to flow with a uniform 0.33-mm sand, data were recorded on the movement of individual rocks having intermediate diameters from about 0.1 to 0.5 foot. The experiments were conducted in a flume 2 feet wide by 60 feet long and for most runs, depth was held...
Studies of fluid inclusions I: Low temperature application of a dual-purpose freezing and heating stage
E. Roedder
1962, Economic Geology (57) 1045-1061
The design and operation of a microscope freezing stage developed for use at magnifications up to 500X are described. It makes possible studies of low-temperature phase changes such as the freezing of a saline water phase, and hence an estimate of the total salt concentration, in fluid inclusions as small as 10 microns (10-6 milligram in...
The origin of jasperoid in limestone
T.G. Lovering
1962, Economic Geology (57) 861-889
The name jasperoid has been applied to rocks that consist mainly of silica and that have formed by replacement. This paper considers only those jasperoids formed by replacement of limestone. Major problems involved in the origin of such jasperoid include: source of the silica; nature of solutions that dissolve, transport, and precipitate silica; and...
Controlled induced recharge tests at Kalamazoo, Mich
Morris Deutsch
1962, Journal - American Water Works Association (54) 181-196
This article discusses the results of a controlled field testing program, which indicated that definite hydraulic and other advantages may be gained from induced recharging as practiced at Kalamazoo, Michigan. Results include the following: water levels and artesian pressures can be maintained at high stages, the results are lower pumping...
Use of thermometry in hydrogeologic studies of glacial deposits at Worthington, Minnesota
R.J. Schneider
1962, Geological Society of America Bulletin (73) 1305-1308
Precise measurements of fluctuations of ground-water temperature based on monthly readings in shallow glacial-outwash aquifers may be used to study ground-water movement and recharge. An increase in storage in the shallow basin of Okabena Lake, Worthington, Minnesota, permits the water to cover a much larger area and probably increases the opportunity for infiltration of...
Paleozoic seas of central Idaho
Clyde P. Ross
1962, Geological Society of America Bulletin (73) 769-793
Some recent paleogeographic maps indicate that central Idaho was part of a major geosyncline throughout Paleozoic time. This concept, apparently based on thick marine accumulations far apart on the margins of the region, is inconsistent with field data. Within the area of the Idaho batholith, Permian(?) volcanic rocks rest either on batholithic rocks...
Temperature correction in conductivity measurements
Stanford H. Smith
1962, Limnology and Oceanography (7) 330-334
Electrical conductivity has been widely used in freshwater research but usual methods employed by limnologists for converting measurements to conductance at a given temperature have not given uniformly accurate results. The temperature coefficient used to adjust conductivity of natural waters to a given temperature varies depending on the kinds...
Glass electrodes sensitive to divalent cations
R.M. Garrels, M. Sato, M.E. Thompson, A.H. Truesdell
1962, Science (135) 1045-1048
Glass electrodes suitable for measurement of divalent cations have been made and tested. Empirical and theoretical electrode equations have been presented to describe electrode behavior in a variety of aqueous solutions. Most electrodes show response interpretable as showing nearly ideal solid-solution behavior of the cations in the glass surface. The...
Hydrology
E. L. Hendricks
1962, Science (135) 699-705
An understanding of water in relation to earth processes requires the collaboration of many disciplines....
Records of wells and ground-water quality in Burlington County, New Jersey
F. Eugene Rush
1962, Report
<This basic-data report is limited to the presentation of selected drillers' logs and their geologic correlations, well data, and chemical analyses of water from wells in Burlington County, N. J. The county lies within the Coastal Plain province; it is underlain by unconsolidated sediments of Quarternary, Tertiary, and Cretaceous...
Physical properties of evaporite minerals
Eugene C. Robertson
1962, Trace Elements Investigations 821
The data in the following tables were abstracted from measurements of physical properties of evaporite minerals or of equivalent synthetic compounds. The compounds considered are the halide and sulfate salts which supposedly precipitated from evaporating ocean water and which form very extensive and thick "rock salt" beds. These beds are...
Diffusion features of uranium-vanadium deposits in Montezuma Canyon, Utah
L.C. Huff, F. G. Lesure
1962, Economic Geology (57) 226-237
Uranium-vanadium deposits in the Salt Wash Member of the Morrison Formation in Montezuma Canyon, San Juan County, Utah, exhibit zoning that is interpreted as a result of metal transport by diffusion. The concentric zones consist of a brown nonmineralized core, an olive-gray mineralized shell, and a gray nonmineralized outer zone. The...
The Vigil Network
Luna Bergere Leopold
1962, International Association of Scientific Hydrology - Bulletin (7) 5-9
Those of us who seek to explain the variations in hydrologic phenomena such as may be observed in the occurrence of floods or in changes in the shape of river channels are painfully aware of the lack of adequate data. Our existing data, collected mainly to serve immediate practical needs...
Records of selected wells and springs, selected drillers' logs of wells, and chemical analyses of ground and surface waters, northern Utah Valley, Utah County, Utah
Seymour Subitsky
1962, Utah Basic-Data Report 2
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1956-59 by the U.S. Geological Survey...
Distribution and detoxication of toxaphene in Clayton Lake, New Mexico
Burton J. Kallman, Oliver B. Cope, Richard J. Navarre
1962, Transactions of the American Fisheries Society (91) 14-22
The fate of toxaphene, applied in three treatments at a total calculated concentration of 0.05 p.p.m. to Clayton Lake, New Mexico, was followed over a 1.5-year period. A detailed description of the chromatographic method of analysis is given. Water concentrations of toxaphene were higher in leeshore samples than in windward...
Study of natural glasses through their behaviour as membrane electrodes
A.H. Truesdell
1962, Nature (194) 77-79
THE low-temperature chemical alteration of natural glass occurs in two stages: an initial stage in which it remains glassy but absorbs as much as 6 per cent water1, and a final stage in which devitrification to clay minerals, with release of silica, occurs2,3. During the first stage the composition of...
Comparative toxicity of 3-trifluormethyl-4-nitrophenol (TFM) to larval lampreys and eleven species of fishes
Vernon C. Applegate, Everett L. King
1962, Transactions of the American Fisheries Society (91) 342-345
The tolerances of larval lampreys, rainbow trout, and 10 species of warmwater fishes to 3-trifluormethyl-4-nitrophenol (TFM), a selective lamprey larvicide, were determined in three dilution waters of different physical and chemical characteristics. Differential toxic effects of the chemical to larval lampreys and test fishes varied broadly with the species of...
