Preliminary Report on the Stratigraphy of the Park City and Phosphoria Formations and an Analysis of the Distribution of Phosphate in Utah

Description: "The Purpose of this paper is to present a preliminary discussion of the stratigraphy of the park city and phosphoric formations with special emphasis on the phosphatic parts and to discuss the distribution of phosphate in Utah. The Mississippian deposits are discussed only briefly because of the lack of new data concerning them"

Chattanooga shale investigations along the Sequatchie anticline of Tennessee and Alabama

Description: "The results of an investigation of the Chattanooga shale along the Sequatchie anticline of Tennessee and Alabama are summarized in this report. The project was of an exploratory nature designed to 1) obtain fresh core samples from areas where analyses of outcrop samples showed uranium contents as high or higher than those of the Youngs Bend area in DeKalb County, Tenn.; 2) learn more about the distribution and thickness of the shale in those areas and, if necessary, do some geologic mapping; 3) observe general topographic, drainage, and geologic conditions that would affect the mining of shale."

Thorium and rare earth minerals in the Powderhorn district, Gunnison County, Colorado

Description: "Thorium deposits were discovered in the Powderhorn district in 1949. This district has long been known for its occurrences of alkalic igneous rocks, of which the best known is the Iron Hill complex (Larsen, 1942). Some of these alkalic rocks contain titanium, barium, strontium, rare earths, thorium, and niobium in greater percentages than those of most igneous rocks. A study of the thorium deposits was undertaken to obtain more information on the geologic relation of minor elements, particularly rare earths, and thorium, to alkalic igneous rocks, and to evaluate the economic significance of the Thorium deposits."
