From introduction: Twenty-nine samples of sedimentary rocks of Triassic age from the Sun Valley uranium mine in northern Arizona were analyzed spectrographically, and 11 of these samples contained 0.005 to 0.1 percent of the rare metallic element, rhenium.

From introduction: A reconnaissance of Arizona uranium deposits was started in October 1950 and continued through April 1951. A total of six man--months was spent by H. C. Granger, E. P. Kaiser, and J. W. Adams. About 40 properties were examined and, of these, six were mapped by plane-table method and six were sketch-mapped. This reconnaissance was not intended as a complete evaluation of all Arizona deposits; other areas and occurrences were not examined during the investigations and are not discussed in this report.

From abstract: A small quantity of uranium ore was shipped from the White Oak No. 1 mine, Pajarito mining district, Santa Cruz County, Ariz., in 1952. The uranium is associated with oxidized lead ore in a shear zone that cuts rhyolite 'porphyry of Tertiary(?) age. The uranium minerals -- kasolite, uranophane, dumontite, autunite, and possibly radioactive pyromorphite -- are concentrated along small, discontinuous fractures, and accordingly the ore bodies are small and widely dispersed.

From abstract: During part of February and March 1953, reconnaissance examinations for radioactive material were made at 12 localities in the Yuma Air Force Base gunnery range in southern Yuma County, Ariz. The Yuma gunnery range, which is adjacent to the west edge of the Luke and Williams Air Force Bases gunnery range, is characterized by block faulted, elongate mountain ranges composed essentially of schist, gneiss, and granite of pre-Cambrian to Mesozoic age and separated by broad alluvial basins.

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.
