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 Capitol Reef, which is on the east and northeast flanks of a structural and topographic dome, The uranium deposits are in the basal part of the Shinarump conglomerate. Zippeite and metatorbernite are the uranium minerals found, and are associated with copper minerals, carbonaceous matter, clay beds, a thick bleached zone at the top of the Moenkopi formation, and channels or scours in the top of the Moenkopi. The highest radioactivity is in a clay bed at the base of the Shinarump conglomerate, and was detected at 7 localities between Grand Wash and Capitol Gorge, at the Birch Spring prospect in Moonie Draw, and at the Oyler mine in Grand Wash.

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 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 the sources of about 1,400 samples of samples of mine, mill, and smelter products that were collected by the U.S. Geological Survey. In addition, the "kind of material sampled, i.e. ores, concentrates, middlings, tailings, flue dusts, and so forth, and the radioactivity of the samples are listed in the report."

Report discussing geophysical observations in parts of the Grants district of McKinley County, New Mexico. This study had the "dual objective of investigating the unusual occurrence of negative aeromagnetic anomalies in close association with airborne radioactivity anomalies, and of investigating other geophysical methods which might assist directly or indirectly in the search for uranium ores in the Grants district."

Report discussing a study regarding the highly radioactive Tertiary porphyries, which were found in Colorado.

Report discussing a the presence of volcanic debris in sandstones containing uranium, and this volcanic debris' possible use in identifying uranium origins.
