Structural map of the King Tutt Mesa, East Carrizo District, in New Mexico produced for the U.S. Atomic Energy Commission's mining operations. Scale 1:24,000

A report regarding plans for the Geological Survey's investigations of uranium in pre-Morrison formations in southern Utah, Northern Arizona, and Northwestern New Mexico.

Preliminary recommendations are presented for drilling the area on a 1,000-foot grid to provide final elevation of the East Carrizo mining district.

Report documenting work to map in detail the Roy Mesa and Enos Johnson claim areas so that ore guides could be determined and the areas could be evaluated for drilling and to complete a general reconnasaince of the favorable Mesozoic.

Letter from L. E. Cowling to Truett Latimer discussing opposition from many to an Insurance Policy Approval Bill, as it would give more authority to the National Association of Insurance Commissioners rather than the State Insurance Department.

Report summarizing information regarding the mineralogy of uranium ores of the Colorado Plateau. The report includes sections on classification, mineralogy of the primary unoxidized ores, oxidation sequence and mineralogy of vanadiferous uranium ores, mineralogy of oxidized nonvanadiferous uranium ores, relation of oxidation to water saturation of ore, relative stability and size of oxidized deposits, secondary enrichment, and time and depth of oxidation.

The following document provides a mineralogical and geological map of the Colorado Plateau providing deposits and groups of deposits that have been found to produce 1,000 tons or more of uranium-vanadium within December 31, 1953.

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.

The following report covers the study of electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting.

From abstract: "Stratigraphic studies of the Triassic and associated formations have been made in southeastern Utah and adjoining parts of Colorado and Arizona. These studies have followed five principal lines of investigation: regional stratigraphy, sedimentary petrology, pebble studies, sedimentary structure studies, and lithofacies studies."

Report discussing the investigation of the chemical composition of sandstone-type uranium ores and unmineralized sandstones of the Colorado Plateau. Spectrographic and chemical analyses was used.

This is a tectonic map of the Colorado Plateau.

From introduction: A rapid appraisal of the carnotite resources of the Salt Wash sandstone member of the Morrison formation in the Carrizo Mountains area was undertaken by the U. S. Geological Survey late in 1951 in connection with its current project of geologic mapping of the area. Though brief and preliminary, this report provides a summary of production trends and estimated reserves in the area and indicates as far as possible the total potential of the area as a source of uranium. This information may be helpful in planning new milling facilities or other measures to encourage a higher rate of production.

From Purpose, Scope, and Methods: The objective of this study was an evaluation of resources of the Carrizo Mountains area. Four factors: distribution of ore bodies, relation of uranium to the host rock, relation of ore to structure, and circumstances that might precipitate uranium were studied in search of data bearing on manner of distribution of ore, the time and causes of deposition, and the probable source of the uranium-bearing solutions.
