Ground-water data collected in the Missouri River basin units in Kansas during 1955
B.J. Mason
1956, Report
Ground-water studies in the Missouri River Basin were begun by the United States Geological Survey during the fall of 1945 as a part of the program for development of the resources of the basin by the U.S. Bureau of Reclamation and other Federal Agencies. The studies of the ground-water resources...

A.W. Helz
1956, Trace Elements Investigations 579
A rapid-scanning microphotometer is described with which a 10-inch spectrum may be scanned in two minutes. The resulting chart may be 60, 300, or 1,500 cm long (wavelength scale) and 4 cm high (intensity scale). Commercially available components are used....

Mary Eleanor Thompson, Carl Houston Roach, Robert Meyrowitz
1956, Trace Elements Investigations 582
Duttonite, a new quadrivalent vanadium oxide from the Peanut mine, Montrose County, Colo., has the formula VO(OH)2. The mineral occurs as crusts and coatings of pale-brown transparent platy crystals, as one of the first oxidation products of montroseite ore. It is associated with melanovanadite and abundant crystals of hexagonal...
Some observations on rutherfordine
Joan R. Clark, C. L. Christ
1956, Trace Elements Investigations 584
The optical properties of rutherfordine, UO2CO3, previously determined on microscopic crystals, have been redetermined on considerably larger crystals; and the relations among the indices of refraction, the morphology, and the crystal structure have been examined. Rutherfordine is orthorhombic, biaxial positive, with α = 1.715, β = 1.730, γ =...
Behavior of Colorado Plateau uranium minerals during oxidation
Robert Minard Garrels, C. L. Christ
1956, Trace Elements Investigations 588
Uranium occurs as U(VI) and U(IV) in minerals of the Colorado Plateau ores. The number of species containing U(VI) is large, but only two U(IV) minerals are known from the Plateau: uraninite, and oxide, and coffinite, a hydroxy-silicate. These oxidize to yield U(VI) before reacting significantly with other...
A fluorimetric study of the thorium-morin system
Robert G. Milkey, Mary H. Fletcher
1956, Trace Elements Investigations 589
Thorium reacts with morin to yield a yellow complex that fluoresces when irradiated with ultraviolet light. The effect on the fluorescence of such variable as concentration of acid, alcohol, thorium, morin, and complex; time, temperature, and wavelength of exciting light are studied to determine experimental conditions yielding maximum fluorescence....
Botanical prospecting for uranium in the Circle Cliffs area, Garfield County, Utah
F. J. Kleinhampl, Carl Koteff
1956, Trace Elements Investigations 604
<Plant-analysis prospecting may be used to locate uranium deposits in the Circle Cliffs area where the deposits lie as much as 70 feet beneath the surface of benches developed on the Shinarump member of the Chinle formation. The Shinarump comprising the benches is thicker than 70 feet at many...
Uranium in carbonaceous rocks in the Townsend and Helena valleys, Montana
George E. Becraft
1956, Trace Elements Investigations 581
Uranium-bearing carbonaceous shale and lignite beds are exposed in five areas in the Townsend and Helena Valleys in western Montana. The greatest number of exposures is in an area of several square miles northeast of Winston in the Townsend Valley. The uranium-bearing beds are in the lower part...
Summary of the mineralogy of the Colorado Plateau uranium ores
Alice D. Weeks, Robert Griffin Coleman, Mary E. Thompson
1956, Trace Elements Investigations 583
In the Colorado Plateau uranium has been produced chiefly from very shallow mines in carnotite ores (oxidized vanadiferous uranium ores) until recent deeper mining penetrated black unoxidized ores in water-saturated rocks and extensive exploration has discovered many deposits of low to nonvanadiferous ores. The uranium ores include a wide...

The determination of calcium in phosphate, carbonate, and silicate rocks by flame photometer
Henry Kramer
1956, Trace Elements Investigations 623
A method has been developed for the determination of calcium in phosphate, carbonate, and silicate rocks using the Beckman flame photometer, with photomultiplier attachement. The sample is dissolved in hydrofluoric, nitric, and perchloric acids, the hydrofluoric and nitric acids are expelled, a radiation buffer consisting of aluminum, magnesium, iron, sodium, potassium,...

Occurrence of selenium in sulfides from some sedimentary rocks of the western United States
Robert G. Coleman, Maryse Delevaux
1956, Trace Elements Investigations 632
Investigations of the minor- and trace-element content of sulfides associated with uranium ore deposits from sandstone-type deposits have shown that selenium commonly substitutes for sulfur. The Morrison formation and Entrada sandstone of Jurassic age and the Wind River formation of Eocene age seem to be seleniferous stratigraphic zones; sulfides deposited...
Abundance and distribution of uranium and thorium in zircon, sphene, apatite, epidote, and monazite in granitic rocks
Patrick M. Hurley, Harold W. Fairbairn
1956, Trace Elements Investigations 636
Analyses were made of uranium and thorium in ziircon, sphene, apatite, epidote, and monazite separated as accessory minerals from samples of granitic rock from widely scattered localities to indicate the abundance and distribution of these two elements among the five mineral phases. For any pair of mineral phases the distribution...
Some uranium occurrences in west Texas
D. Hoye Eargle
1956, Trace Elements Investigations 574
Uranium minerals have been found at several localities in west Texas. In the King Mountain area in southwestern Upton County carnotite forms coatings along joint planes and in borings in marine Cretaceous limestone. In the Hueco Mountains area in El Paso and Hudspeth Counties carnotite and similar secondary uranium minerals...

Pyrite-uranium polycrystal
A.G. King
1956, Trace Elements Memorandum 1012
A texture was observed in a sample of ore in 'Which pyrite and uraninite occurred as thin alternate layers paralleling crystal faces of a pyrite nucleus. This texture could be formed either by replacement or by syntaxis. Although syntactic growth forming polyerystals of two chemically dissimilar minerals has not been...
Semiquantitative spectrographic analysis and rank correlation in geochemistry
Francis J. Flanagan
1956, Trace Elements Investigations 628
The rank correlation coefficient, rs, which involves less computation than the product moment correlation coefficient, r, can be used to indicate the degree of relationship between two elements. The methods is applicable in situations where the assumptions underlying distribution correlation theory may not be satisfied. Semiquantitative spectrographic analyses can be...
The determination of uranium (IV) in apatite
Roy S. Clarke Jr., Zalman S. Altschuler
1956, Trace Elements Investigations 637
Geologic and mineralogic evidence indicate that the uranium present in apatite may proxy for calcium in the mineral structure as U(IV). An experimental investigation was conducted and chemical evidence was obtained that establishes the presence of U(IV) in apatite. The following analytical procedure was developed for the determination of U(IV). Carbonate-fluorapatite...
