Abstract: Reconnaissance for uranium in coal and black shale in New Mexico during 1952 was largely an extension of work initiated during the 1951 field season. No uranium deposits of economic interest were found, although minor amounts of uranium were noted at several localities.

Report discussing the results of geological studies that have been conducted in the Clancy Creek in the Jefferson City Quadrangle of Jefferson County, Montana. The location is of interest due to the discovery of several radioactivity anomalies and secondary uranium minerals in the area.

Report discussing an Chattanooga shale adit for laboratory test samples of rock and gaining information regarding mining conditions.

Report discussing an exploratory drilling program in the Charles T. area and vicinity during the period from November 1947 and September 1949. "The purpose of the exploration was to discover new carnotite deposits to support milling operations on the Colorado Plateau, and to appraise the uranium and vanadium resources of the area explored."

Analysis of geologic, hydrologic, and geophysical data obtained in and around Yellow Creek core hole No. 1, Rio Blanco County, Colorado, indicate a 1,615-foot section of oil shale was penetrated by the hole. Geophysical log data indicate the presence of 25 gallons per ton shale for a thickness of 500 feet may be marginal. The richest section of oil shale is indicated to be centered around a depth of 2,260 feet. Within the oil shale the interval 1,182 to 1,737 feet is indicated to be relatively structurally incompetent and probably permeable. Extension of available regional hydrologic data indicate the oil shale section is probably water bearing and may yield as much as 1,000 gallons per minute. Hydrologic testing in the hole is recommended.

A report about the optical properties of rutherfordine.

Report discussing an investigation of radioactive Chattanooga black shale found in east central Tennessee.

From abstract: The U.S. Atomic Energy Commission, through the Office of Test Operations, Albuquerque Operations Office, plans to detonate a nuclear device in a massive salt bed 1,200 feet beneath the land surface. The project, known as Project Gnome, is an element of the Plowshare program--a study of peacetime applications of nuclear fission. The location of the proposed underground shot is in a sparsely-populated area in southeastern Eddy County, N. Mex., east of the Pecos River and about 25 miles southeast of the city of Carlsbad.

Report discussing a method for the volumetric estimation of the oil yield of oil-bearing shale. The method can be applied to both shale and phosphatic shale.

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

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.

From introduction: The geologic studies in the Ul2e.03a and Ul2e.03b tunnels were conducted as part of the Geological Survey's investigations for the Vela Uniform program, Project Shade, and were completed for the purpose of 1) determining the preshot lithologic, structural, and chemical and physical properties of the tuffs exposed in the tunnels for comparison wits postshot geologic data, and 2) evaluating these data in order to predict the geologic effects of the planned nuclear explosion at tie end of the tunnels.

From introduction: The geologic studies in the U12b.08 tunnel were conducted by the U. S. Geological Survey on behalf of the U. S. Atomic Energy Commission for the purpose of determining the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel. These data will be used in evaluating the geologic effects of the explosion by comparison with similar post-shot geologic data.

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

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.

Report discussing the progress made on various geologic studies during the period from April 1 to June 30, 1952.

The following report was undertaken to overcome poisoning difficulties that are caused by passage of solutions containing nickel through the Jones reductor/zinc amalgam reductors.

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 the results of a geological study of the Idaho Springs-Central City area of the Front Range mineral belt. The study was still in progress at the time of publication.

A report regarding a geological survey of the geology and ore deposits of the Freeland-Lamartine District, Clear Creek County, Colorado. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

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 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.

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.

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