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

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.

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 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.

Report discussing airborne radioactivity surveys, aimed at finding uraniferous phosphate deposits, in ten areas of Florida. A subsequent ground investigation of two radioactivity anomalies out of eight was conducted. Information on radioactivity measurements for each area is given as well as conclusions.

A report about uranium bearing multiple oxide minerals first recognized in the jig-bed concentrate of the Tyee Mining Company's gold dredge on the Red River. The gravels of the placer deposits were derived from the Idaho batholith and a roof pendant of Precambrian rocks in the batholith.

A report about the Central City district and adjoining mining areas in the central part of the front range mineral belt which has supplied small quantities of uranium ore intermittently since the discovery of pitchblende at Central City in 1871.

Report discussing the relationship between uranium deposits and hypogene mineral zoning in the Front Range mineral belt of Colorado. This report is mostly based on work done by other geologists.
