A report about a sample of uranium-bearing conglomerate from the Shinarump member of the Chinle formation in northern Arizona was disaggregated in an ultrasonic separator.

Report summarizing the general geologic relations of some uranium deposits in the San Juan Basin, speculating on the origin and localization of some individual deposits and the entire SanJuan Basin mineral belt, and attempting to appraise the chances for discoveries of additional deposits.

A report about a geometry based on the reciprocal lattice concept and geometrical construction of Ewald needed for the interpretation of transmission electron-diffraction single-crystal patterns.

The following report covers the study of electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting.

From introduction: This report contains the results of a detailed geological and uranium deposits study made of the Monument Valley.

Abstract: "Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part of the Tertiary. The individual ages determined on zircon from 2 rocks from southeastern Alaska and 1 from east-central Alaska gave results of 90, 100, and 96 million years; those determined on 4 rocks from central Alaska gave results of 47, 56, 58, and 51 million years."

A report about a new quadrivalent vanadium oxide from the Peanut mine named Duttonite which has the formula VO(OH)2. The mineral occurs as crusts and coatings of pale-brown transparent platy crystals.

Report discussing the exploration of the uranium ore-containing ancient channels of the Shinarump member of the Chinle formation of Late Triassic age through the use of a refraction seismograph.

Report discussing the geology and numerous ore deposits of the Chicago Creek area in Clear Creek County, Colorado. Prior to this report, gold, silver, copper, lead, zinc, and uranium were produced from this area.

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."

A report about the optical properties of rutherfordine.

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

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 the U.S. Geological Survey's investigation for uraniferous coal in the central region of the Great Divide Basin of Sweetwater County, Wyoming.

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

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.
