Report discussing a study of uraniferous lignite collected from three coal beds from Harding County, South Dakota. The report contains information regarding the location and geologic setting of the coal, the materials studies, coal petrologic studies, and a discussion of results.

Report outlining information regarding uranium and geology of uranium. Sections include geochemistry of uranium, influence of orogeny on concentration of uranium, types of uranium deposits, and general criteria for prospecting.

A report discussing features of uranium that may be important in searching for and appraising deposits.

Report discussing a study in which ten samples of carnotite and metatyuyamunite ore that contain more than 0.1 percent lead area analyzed for uranium, radium, and lead.

Abstract: "A rapid-scanning microphotometer is described with which a 10-inch spectrum may be scanned in two minutes. The resulting chart may be 60, 300, or 1,500 cm long (wavelength scale) and 4 cm high (intensity scale). Commercially available components are used."

Report summarizing findings of investigations for radioactive source materials in Alaska from 1945 through 1954, and assessing possible Uranium sources in the state.

From introduction: A tectonic map for the northern part of the Cordilleran Foreland was compiled to aid in establishing the geologic setting of uranium deposits within the region, and to determine what relationships, if any, exist between the distribution of uranium deposits and localities, and the regional tectonic pattern (Osterwald, 1955). The relationships might suggest new areas favorable for the discovery of uranium deposits in the Cordilleran Foreland as well as in other areas with similar tectonic history. The map will show the distribution of crest lines and troughs of folds, faults, uranium deposits and localities, and areas of volcanic activity. Outcrop areas of Precambrian and post-Eocene rocks are shown to designate the relative age of structures. Where possible the Precambrian rocks are subdivided into structural types, so that their influence on younger deformations may be inferred. The map of eastern Montana is one of a series being prepared before the final map is assembled (fig. 1.).

From abstract: Field work leading to this report was done by the U. S. Geological Survey for the Division of Raw Materials of the U. S. Atomic Energy Commission, Nearly 24 townships were mapped in the central part of the Great Divide Basin, Sweetwater County, Wyoming, Fourteen of these townships contain outcrops of uranium-bearing coal. Thirty coal beds were mapped, but only seven of them have uranium-bearing coal reserves as defined in this report.

Report discussing a comparison of three methods of sample splitting for grain counting: the microsplit, the cone splitter, and hand quartering.

A report discussing an examination of the Dismal Swamp property for niobium, tantalum, and uranium.

Report discussing a study in which "a suite of alkalic rocks from the Beemerville, NJ, intrusive body was separated and the percentages of their accessory minerals were determined."

Report discussing the geology of the Red House Cliffs area, which comprises 296 square miles of canyon and plateau country in southwestern San Juan County, Utah.

Report discussing the geology of the Wood vein and East Calhoun mine areas of Gilpin County, Colorado.

Report discussing uranium deposits and their origins. Sections include information regarding geochemistry of uranium, occurrence of uraniferous deposits, uraniferous igneous rocks, uranium in vein deposits, sandstone-type deposits, uraniferous coal and associated carbonaceous shale, and uraniferous marine sedimentary rocks.

Abstract: An automatic micromuffle for the determination of the ash content of small samples of carbonaceous material is comprised of a furnace of the radiant-heating type with a direct reading pyrometer for temperature control. This furnace can be assembled with a minimum of labor using parts available from scientific laboratory apparatus companies.

Abstract: "All published data on the hafnium content and hafnium/zirconium ratio in minerals and rocks have been compiled." Information regarding hafnium and zirconium content and the ratio Hf/Zr in the earth's crust and in rocks as well as of minerals is included.
