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...
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...
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 =...
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...

Uranium distribution in pseudowollastonite slag from a phosphorus furnace
Edward Young, Zalman S. Altschuler
1956, Trace Elements Investigations 615
Silicate slag from the Victor Chemical Company phosphorus furnace at Tarpon Springs, Fla., has been found to consist essentially of pseudowollastonite, α-CaSiO3. The first-formed crystals are euhedral laths which form a mesh making up most of the slag. As the slag continues to solidify, its composition changes slightly and more...

Diatremes and craters attributed to natural explosions
Eugene Merle Shoemaker
1956, Trace Elements Memorandum 1090
Diatremes - volcanic pipes attributed to explosion - and craters have been studied to infer the ultimate causes and physical conditions attending natural explosive processes. Initial piercement of diatremes on the Navajo reservation, Arizona was probably along a fracture propagated by a high-pressure aqueous fluid. Gas rising at high velocity along...

Thick sequences of silicate and carbonate rocks of sedimentary origin in North America an interim report
John David Love
1956, Trace Elements Memorandum 1088
Thick sequences of silicate and carbonate rocks of sedimentary origin have been investigated in 64 areas in North America. The areas containing the thickest and most homogeneous stratigraphic sections more than 1,000 feet thick, buried at depths greater than 10,000 feet are: 1. Uinta Basin, Utah, where the Mancos shale...
