Geology of Devils Tower National Monument, Wyoming
Charles Sherwood Robinson
1956, Bulletin 1021-I
Devils Tower is a steep-sided mass of igneous rock that rises above the surrounding hills and the valley of the Belle Fourche River in Crook County, Wyo. It is composed of a crystalline rock, classified as phonolite porphyry, that when fresh is gray but which weathers to green or brown....
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...
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...
Gravity survey of Ogden Valley, Weber County, Utah
Samuel Woods Stewart
1956, Open-File Report 56-112
Ogden Valley is a northwest trending valley within the Wasatch Mountains of north-central Utah. On the basis of geological evidence Ogden Valley is believed to be structurally controlled by normal faults along both the east and west margins. Gravity measurements in the valley definitely indicate a fault with at least...
An inferred relationship between some uranium deposits and calcium carbonate cement in southern Black Hills, South Dakota
Garland B. Gott
1956, Trace Elements Memorandum 1000
Evidence resulting from geologic mapping in the southern Black Hills indicates that the areas marginal to some of the larger carbonate-cemented sandstones constitute favorable geochemical environments for the localization of uranium deposits. To determine whether these favorable environments are predictable a limited experimental core-drilling program was carried out. An extensive...
