Temple Mountain member, a new member of the Chinle formation in the San Rafael Swell, Utah
Raymond C. Robeck
1956, Trace Elements Memorandum 800
A lithologic unit, referred to as mottled purple and white, or the 'pinto bed,' in the San Rafael Swell has E?nough thickness and continuity to be formally named the Temple Mountain member of the Chinle formationo The member is characterized by the presence of: the interfingering of siltstone, mudstone, and...
Comparison of the pebbles of the Shinarump and Moss Back members of the Chinle formation
Howard Franklin Albee
1956, Trace Elements Memorandum 832
Lithology, color, size, sphericity, and roundness of pebbles from the Shinarurnp and Moss Back members of the Chinle formation were analyzed and compared. The difference in the quartz:quartzite:chert ratios of the pebbles, the presence of limestone and siltstone pebbles, and to a lesser degree,the difference in color of pebbles serve...

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...

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...

The bibliography consists of annotations or abstracts of selected reports that pertain to the geology and occurrence of uranium in marine black shales and their metamorphic equivalents in the United States. Only those reports that were available to the public prior to June 30, 1956, are included. Most of the...
Selected annotated bibliography of the geology of uraniferous and radioactive native bituminous substances, exclusive of coals, in the United States
Harriet Nell Jones
1956, Trace Elements Investigations 536
Native bituminous substances are divided into two groups, 1) bitumens and, 2) pyrobitumens. Bitumens are composed principally of hydrocarbons substantially free from oxygenated bodies, are fusible, and are soluble in carbon disulfide. Native bitumens occur in liquid and solid forms. The native liquid bitumens include all petroleums or crude oils....

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...
