An Occurrence of Rhenium, Associated with Uraninite in Coconino County, Arizona

Description: From introduction: Twenty-nine samples of sedimentary rocks of Triassic age from the Sun Valley uranium mine in northern Arizona were analyzed spectrographically, and 11 of these samples contained 0.005 to 0.1 percent of the rare metallic element, rhenium.

Uranium Deposits of the Carlile Quadrangle, Crook County, Wyoming

Description: From abstract: The uranium deposits in the Carlile quadrangle, southwestern Crook County, Wyo., are in relatively flat-lying sandstone beds in the lower part of the Inyan Kara group of Early Cretaceous age. The Carlile mine has the largest deposit in the quadrangle; the ore minerals are carnotite and tyuyamunite associated with carbonaceous material in a sandstone lens.

Preliminary Report on the Rimini Area, Jefferson City Quadrangle, Jefferson County and Lewis and Clark County, Montana

Description: Abstract: A number of radioactivity anomalies and secondary uranium minerals have been found in the Rimini area near the northwestern margin of the Boulder batholith. Most of the anomalies are associated with chalcedonic vein zones that consist of one or more veins of cryptocrystalline and fine-grained quartz in silicified quartz monzonite and alaskite. Seventeen of the anomalies were found along veins that contain base and precious metals; nine were along veins in the vicinity of the village o… more

Progress Report on Geologic Studies in the Capitol Reef Area, Wayne County, Utah

Description: From abstract: During 1951 about 60 square miles of the Capitol Reef area, Wayne County, Utah, the northern end of the Waterpocket Fold, was mapped by plane-table methods on a scale of 1:62, 500. Formations, with an approximate aggregate thickness of 3, 200 feet, range from the Coconino sandstone of Permian age to the Navajo sandstone of Jurassic (?) age. About 35 linear miles of Shinarump conglomerate of Triassic age was examined in detail. Cliffs 900 to 1, 000 feet high form the west face of … more

Relation of Uranium to Hypogene Mineral Zoning in the Front Range Mineral Belt, Colorado

Description: From abstract: Many of the mining districts of the Colorado Front Range mineral belt contain mesothermal sulfide ores that exhibit a zonal distribution. Present data indicate that in most of the zoned districts pitchblende and/or secondary uranium minerals are most abundant in a transition zone between central areas containing predominantly pyritic gold ores and peripheral areas containing dominantly lead-zinc-silver deposits. Copper in the form of chalcopyrite is also probably more abundant in… more

An Investigation of Airborne Radioactivity Anomalies in the Rock Corral Area, San Bernardino County, California

Description: From abstract: The investigation in the Rock Corral area was undertaken to determine the relationship between 1) the anomalously high radioactivity recorded during an airborne survey and 2) the distribution and mineralogic mode of occurrence of radioactive material.

Airborne Radioactivity Surveys for Phosphate in Florida

Description: Introduction: Deposits of phosphate in Florida, located beyond the limits of known producing areas, have been reported by prospectors and mining companies. Much of the information has been based upon prospecting and exploration which was undertaken many years ago and as a result the published data relating to the occurrence of these deposits are fragmentary, and few details relating to specific locations and extent are available.

Study of Radioactive Equilibrium in Carnotite Ores of the Colorado Plateau

Description: Report discussing a geological study for which the objective was to determine the age of Colorado Plateau carnotite. "In addition to quantitative analyses of uranium and lead, the radium-uranium equilibrium of each sample was studied."

Some Natural Variations in the Relative Abundance of Copper Isotopes

Description: Abstract: "The relative isotopic abundance of copper has been measured in a number of minerals. Suites of samples from Michigan and the Colorado Plateau have been examined to determine if local variations due to isotopic exchange or diffusion could be found. The relative isotopic abundance of copper in specimens from a number of other places was also determined. The variations noted were small but in most cases were felt to be significant because they were larger than the experimental error (0.… more

Comparison of Thickness, Grade, and Depth of Radioactive Layers as Determined by Gamma-Ray Logging and by Core Sampling

Description: Abstract: "Thickness, grade, and depth data were obtained by analyzing gamma-ray logs and core samples from 56 diamond drill holes penetrating uranium deposits in the Colorado Plateau. The data from the two methods were compared to determine variations found in gamma-ray log interpretation and chemical and radiometric analyses of the drill core. Correlations within each parameter varied among the drilling areas analyzed. Gamma-ray interpretations of grade compared to chemical analyses were with… more
