A report about a 22-square mile tract of pre-Cambrain rocks and veins containing thorium mapped at the scale of 1:6,000 located on the west flank of the Wet Mountains, Custer and Fremont Counties, northeast of Westcliffe, Colorado.

A report about the ages of the four great batholiths in the western United States.

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."

The following report is the fourth in a series of reports on rare and uncommon elements prepared by the Geological Survey. This report covers columbius and tantalus, two chemical elements belonging to the fifth group of the periodic table and quinquevalent in most of their compounds.

A report which presents the results of a study of the uranium resources of the Green River and Henry Mountains districts, Utah, and is part of a series of similiar reports synthesizing the geologic relations of uranium deposits in all formations on the Colorado Plateau.

Report discussing a study in which "thorium nitrate is quantitatively extracted by mesityl oxide from solutions saturated with aluminum nitrate even in the presence of relatively large amounts of phosphate."

From Abstract: "This paper presents the methods of chemical analysis that were used to aid in mineralogic studies of Colorado Plateau carnotite for purposes of determining age of materials."

Report discussing a study of 1,000 Gamma-ray logs of oil wells in the central part of the United States which confirmed the use of these logs for the detection of radioactive deposits.

A report about a new uranium mineral from the Fuemrol No. 2 mine, Emery County, Utah, named abernathyite.

A report pertaining to uranium which has been found in two stratigraphic zones in rocks of permian age in northern Texas and south-central Oklahoma.

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 (0.1 percent in the ratio). A total spread of +3 to -8 parts per mil compared to the standard was found in the specimens tested."

Report discussing uranium oxides, their thermodynamic relations, and how these relations connect to the oxidation states of uranium ores found at the Colorado Plateaus. This report provides information regarding thermodynamic properties of some compounds and ions of the U-O-H2O system, discussion and interpretation of thermodynamic properties, and a summary with conclusion.

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 within the range of -10 to +25 percent. Most depth measurements determined by gamma-ray log interpretation compared to drill core measurement were within 0.5 percent. Results of the study indicate a need for better thickness definition in both gamma-ray logging and core scanning equipment."

Report discussing a geological experiment in which drill holes in carnotite deposits were logged with the objective of developing a technique for the stratigraphic correlation of ore-bearing beds.

Report discussing a 1951 geological study of about 60 square miles of the Capitol Reef area of Wayne County, Utah. Specifically, the details of the first season's field work on the uranium deposits and on the sedimentary rocks of the area are presented.
