Engineering geology of the Nenana-Rex area, Alaska
Reuben Kachadoorian
1956, Open-File Report 56-67
A geological examination of the Nenana-Rex area, Alaska, was made during August, 1954 by a Geological Survey party consisting of Reuben Kachadoorian, geologist, and Lloyd Plafker, field assistant. The area examined lies in parts of the Fairbanks A-4, A-5, B-4, B-5, C-4 and C-5 quadrangles (fig. 1). A preliminary highway...
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...
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....
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...
Geophysical abstracts 164, January-March 1956
Mary C. Rabbitt, Dorothy B. Vitaliano, S.T. Vesselowsky, and others
1956, Bulletin 1048-A
Geophysical Abstracts includes abstracts of technical papers and books on the physics of the solid earth, the application of physical methods and techniques to geologic problems, and geophysical exploration. A new table of contents, alphabetically arranged, has been adapted to show more clearly the material covered.Abstracts are prepared only of...
Geophysical abstracts 165, April-June 1956
Mary C. Rabbitt, Dorothy B. Vitaliano, S.T. Vesselowsky, and others
1956, Bulletin 1048-B
Geophysical Abstracts includes abstracts of technical papers and books on the physics of the solid earth, the application of physical methods and techniques to geologic problems, and geophysical exploration. The table of contents, which is alphabetically arranged, shows the material covered.Abstracts are prepared only of material that is believed to...
Contributions to the geology of uranium and thorium by the United States Geological Survey and Atomic Energy Commission for the United Nations International Conference on Peaceful Uses of Atomic Energy, Geneva, Switzerland, 1955
Lincoln R. Page, Hobart E. Stocking, Harriet B. Smith
1956, Professional Paper 300
Within the boundaries of the United States abnormal amounts of uranium have been found in rocks of nearly all geologic ages and lithologic types. Distribution of ore is more restricted. On the Colorado Plateau, the Morrison formation of Jurassic age yields 61.4 percent of the ore produced in the United...
