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...
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...
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...
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 =...
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...
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,...

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...
Sources of the elements in the sandstone-type uranium deposits of the Colorado Plateau
Eugene M. Shoemaker, W.L. Newman, A.T. Miesch
1956, Trace Elements Investigations 629
Sandstone-type uranium deposits of the Colorado Plateau are epigenetic. Certain elements have been added locally to the sandstone host to form the deposits; the added fraction of each element in the deposits is call extrinsic to distinguish it from the part present in the original unmineralized host. The principal extrinsic...

The absorption spectra of the complexes of uranium (VI) with some β-diketones
H.I. Feinstein
1956, Trace Elements Investigations 631
The absorption spectra of the complexes of uranium (VI) with four β-dike tones were determined under various conditions of pH, concentration of uranium, and alcohol concentration. Under optimum conditions, the maximum molar absorptivity (31,200) is obtained using 2-furoyltrifluoroacetone. This compares with about 4,000 and 19,000 for the thiocyanate and dibenzoylmethane...
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...

Relationship of sediment discharge to streamflow
B. R. Colby
1956, Open-File Report 56-27
The relationship between rate of sediment discharge and rate of water discharge at a cross section of a stream is frequently expressed by an average curve. This curve is the sediment rating curve. It has been widely used in the computation of average sediment discharge from water discharge for periods...
