First part of an annual report describing studies conducted by researchers at Columbia University to surveyuranium mineralization in the Marysvale, Utah region: "Part I deals with field studies and mineralogical data derived from the laboratory examination of suites collected during the previous summer" (p. 5).

From abstract: A study, consisting of field and laboratory work, was undertaken in an endeavor to establish possible structural mineralization controls associated with the copper-uranium occurrences in the Willaha area, Coconino County, Arizona. Uranium mineralization, apparent at present, is localized along small fissures and vugs and in certain beds and lenses of the middle member of the Kaibab formation(Permian). It is associated with copper and iron oxide staining. Though no definite ore controls were disclosed by this study, at least a limited program of shallow drilling is warranted on the property. This sub-surface exploration should determine possible extensions of known mineralized areas, explore surface radiometric anomalies, and provide data for the determination of possible guides to ore. Deeper exploration may encounter mineralization in other horizons of the Kaibab limestone.
