Notes on the Relationship of Uranium Mineralization and Rhyolite in the Marysvale Area, Utah
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.
Preliminary Memorandum, East Slope Area, Marysvale, Utah
From introduction: Preliminary field data have been assembled as a background for laboratory investigations directed toward interpretation of alteration features in the East Slope area. Such data constitute one of several units which should improve our understanding of the pattern of uranium distribution.
Preliminary Memorandum on the Trinity Mines, Marysvale, Utah
This report provides results from a preliminary study to determine rock types and alteration products that are responsible for an observed abundance of radioactive gas at the Trinity Gold Mine in Utah. It includes an overview of the study and the location, description of the methods and general statements, details about the structure, petrography and mineralogy, and a discussion of findings.
[Marysvale Region Study], Annual Report: July 1, 1951-June 30, 1952, Part 1. A Geologic Guide to the Marysvale Area
Introduction: It is the purpose of this guide to describe the general geological features of the Marysvale area which may aid in exploration for uranium.
[Marysvale Region Study], Annual Report: June 30, 1953-April 1, 1954, Part 1
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).
The East Slope No. 2 Uranium Prospect, Piute County, Utah
From abstract: The secondary uranium minerals autunite, metatorbernite, uranophane (?), and schroeckingerite occur in altered hornfels at the East Slope No. 2 uranium prospect. The deposit, in sec. 6, T. 27 S., R. 3 W., Piute County, Utah, is about I mile west of the Bullion Monarch mine in the central producing area of the Marysvale uranium district. Hornfels, formed by contact metamorphism of bullion Canyon volcanic rocks along the edge of a quartz monzonite stock, is in fault contact with the later Mount Belknap rhyolite.
Proposed Exploration: Papsy's Hope No. 2 Uranium Prospect, Piute County, Utah
From abstract: This report describes the new workings and proposes that additional exploration be undertaken on the Papsy's Hope No. 2 property in Marysville, Utah.
