New occurrences of ferroselite (FeSe2)
R. G. Coleman
1959, Geochimica et Cosmochimica Acta (16) 296-301
Iron selenide from the uranium-vanadium ores of the Colorado Plateau was under investigation when ferroselite was described as a new mineral in Russia by Bur'yanova and Komkov (1955). Association of ferroselite with selenian pyrite and marcasite within discrete areas of these uranium-vanadium deposits suggests an unusual environment of formation. Its association...
Magnetostriction and palæomagnetism of igneous rocks
John W. Graham, A. F. Buddington, James R. Balsley
1959, Nature (183) 1318
IN a recent communication, Stott and Stacey1 report on a “crucial experiment” from which they conclude: “This excellent agreement between the dip and the directions of artificial thermoremanent magnetization of the stressed and unstressed rocks indicates that large systematic errors due to magnetostriction are most improbable in igneous rocks of types...
Semimicrodetermination of combined tantalum and niobium with selenous acid
F. S. Grimaldi, M. Schnepfe
1959, Analytical Chemistry (31) 1270-1272
Tantalum and niobium are separated and determined gravimetrically by precipitation with selenous acid from highly acidic solutions in the absence of complexing agents. Hydrogen peroxide is used in the preparation of the solution and later catalytically destroyed during digestion of the precipitate. From 0.2 to 30 mg., separately or in...
Some preliminary notes on the ground water in the Columbia River basalt
R. C. Newcomb
1959, Northwest Science (33) 1-18
The Columbia River basalt carries groundwater by percolation, largely along tabular interflow zones of variable permeability and continuity. At various places the water occurs under perched, unconfined, and confined conditions; at some places it occurs under all three conditions at different depths. Both initial and tectonic structural features, such as...
Core logs from Bristol, Cadiz, and Danby Dry Lakes, San Bernardino County, California
Allan Mordorf Bassett, D.H. Kupfer, F.C. Barstow
1959, Bulletin 1045-D
Detailed core logs of four holes drilled in Bristol, Cadiz, and Danby Dry Lakes in southeastern San Bernardirio County, Calif., are given in the present report. These 3 dry lakes lie in a chain of basins having a drainage area of 4,000 square miles which is made up of alluvial...
The reclamation of Indian and Abrams creeks in Great Smoky Mountains National Park
Robert E. Lennon, Phillip S. Parker
1959, Special Scientific Report - Fisheries 306
A complete program of stream reclamation was developed and applied on Indian and Abrams creeks in Great Smoky Mountains National Park. A salt-resistivity technique was used to estimate the dilution and velocity of a toxicant in running water. Streamside toxicity trials on resident fishes established minimal, effective concentrations of the...
Magnetic susceptibility of tektites and some other glasses
F. E. Senftle, A. Thorpe
1959, Geochimica et Cosmochimica Acta (17) 234-237
The magnetic susceptibility at several magnetic field strengths of about thirty tektites from various localities have been measured. The susceptibility ranges from 2 × 10−6 to about 7.9 × 10−6 e.m.u./g. Tektites from a given locality have similar susceptibilities. The intensity of magnetization of all the tektites measured is zero or very...
Ground-water resources of Riverton irrigation project area, Wyoming, with a section on chemical quality of ground water
Donald Arthur Morris, O. M. Hackett, K.E. Vanlier, E. A. Moulder, W. H. Durum
1959, Water Supply Paper 1375
The Riverton irrigation project area is in the northwestern part of the Wind River basin in west-central Wyoming. Because the annual precipitation is only about 9 inches, agriculture, which is the principal occupation in the area, is dependent upon irrigation. Irrigation by surface-water diversion was begum is 1906; water is...
Water resource development and management
Luna Bergere Leopold
1959, Journal of the American Water Works Association (51) 821-827
In a sandy, riverside location in Wisconsin, my family has a farm, once abandoned by a previous owner because it would not produce much corn. By the time we bought it – for a pittance – only a few remnants of white pine remained from the magnificent stands made famous...
Geology and quicksilver deposits of the Terlingua district, Texas
Robert G. Yates, George A. Thompson
1959, Professional Paper 312
The Terlingua quicksilver district, which has produced more than 150,000 flasks of quicksilver, is in the southern part of the Big Bend region of southwestern Texas. It is a narrow, eastwest area about 20 miles long and lies mainly in southwestern Brewster County. The district is connected by graded road...
The electrical resistivity meter in fishery investigations
Robert E. Lennon
1959, Special Scientific Report - Fisheries 287
A portable resistivity (or conductivity) meter is easily used in fishery investigations to obtain rapid and precise measurements of the electrical resistance (or conductance) of waters. These measurements can be used to estimate the total dissolved solids content of waters, to facilitate the selection of appropriate gear for efficient electrofishing,...
Burrowing activities of the larval lamprey
Philip J. Sawyer
1959, Copeia (1959) 256-257
Since the appearance in 1950 of Applegate's work on the sea lamprey in Michigan (U. S. Fish and Wildl. Serv., Spec. Sci. Rept.; Fish, No. 55) and the subsequent development of means to...
Determination of uranium in zircon
F. Cuttitta, G. J. Daniels
1959, Analytica Chimica Acta (20) 430-434
A routine fluorimetric procedure is described for the determination of trace amounts of uranium in zircon. It employs the direct extraction of uranyl nitrate with ethyl acetate using phosphate as a retainer for zirconium. Submicrogram amounts or uranium are separated in the presence of 100,000 times the amount of zirconium....
α-Radioactivity of cerium-142
F. E. Senftle, T. W. Stern, V. P. Alekna
1959, Nature (184) 630
JOHNSON AND NIER1 have measured the atomic masses of some of the rare-earth isotopes and have shown that the mass difference cerium-142—(barium-138 + helium-4) is equivalent to 1.68 ± 0.10 MeV. Similar results for the naturally occurring samarium and neodymium isotopes show that the α-active isotope of each element is the one...
Life history of the sea lamprey of Cayugaf Lake, New York
Roland L. Wigley
1959, Fishery Bulletin of the U.S. Fish and Wildlife Service 561-617
A life history study of the sea lamprey, Petromyson marinus Linnaeus, in Cayuga Lake, N.Y., was conducted during 1950, 1951, and 1952. One of the major objectives was to obtain biological data concerning this endemic stock of sea lampreys for comparison with the newly established stocks in the Great Lakes....
