Report discussing geologic structures which localize carnotite deposits of the Colorado Plateau.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

A report about uranium in Colorado which oxidize to yield U(VI) before reacting significantly with other mineral constituents.

The following report analyzes channel samples from two mines (Mineral Joe No. 1 and Virgin No. 3) on the Colorado Plateau that have been studied in detail both mineralogically and chemically.

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.

From introduction: This report details mineral and chemical relations in two uranium-vanadium ores of the Colorado Plateau.

Three maps illustrating distribution of metal deposits in metal-mining districts in Colorado. The first map is a geological survey indicating uranium deposits, rock characteristics, and the location of the Central Mining District in relationship to counties in Colorado. The second map shows pitchblende deposits and bostonite dikes in the Front Range Mineral Belt near Central City, Colorado. The third map near indicates the locations of pitchblende deposits alongside metal vein systems near Central City, Colorado

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

Report discussing the geology and numerous ore deposits of the Chicago Creek area in Clear Creek County, Colorado. Prior to this report, gold, silver, copper, lead, zinc, and uranium were produced from this area.

Report discussing the results of a geological study of the Idaho Springs-Central City area of the Front Range mineral belt. The study was still in progress at the time of publication.

A report regarding a geological survey of the geology and ore deposits of the Freeland-Lamartine District, Clear Creek County, Colorado. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing the zoning of Bitter Creek mine vanadium and uranium deposits. Information regarding field work/acknowledgments, general geology, features of the mine, zoning of the mine, zoning of other parts of the area, origin of the zones, and conclusions are included.

From introduction: Geophysical surveys have been made in the Uravan area, in southwest Colorado, with the aim of providing information on regional geology, especially on those aspects that may not be apparent from surface evidence alone. Aeromagnetic surveys were made in 1952, and regional gravity surveys were made during the summers of 1953 and 1954. Figure 1 shows the area covered. Information on surface geology was obtained from publications, from geologists working on the Colorado Plateau, and from personal observations.

Report discussing information produced from aeromagnetic and regional surveys conducted in the Uravan area of Colorado. This was part of a regional geology study of the Colorado Plateau.

A report which refers to a study that indicated there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore.

The following report covers a study of the electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau province where it is indicated that there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore. This report presents the measurements of resistivity trends.

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.

Report discussing different types of uranium deposits found in Colorado mines and the geological guides which can help locate these deposits.

A report regarding reconnaissance investigations for uranium in the Colorado Front Range and Adjacent Areas.

"This paper summarizes the results of the field studies of the Survey's Reconnaissance Group and outlines some geologic criteria that may be useful in guiding the search for uranium ore. The writers wish to acknowledge the cooperation of the minding companies and individuals who materially aided the program of investigations by reporting radioactive localities and by submitting samples of radioactive rocks and ores."

A report about a reconnaissance of the Sharon Springs member of the Pierre shale in western Kansas and eastern Colorado was conducted during 1954.

A report about uranium content of water from various rocks in certain states in the United States. It attempts to locate areas in which large amounts of uranium in the water will reflect the presence of nearby uranium accumulations.

From introduction: The primary objective of these studies is to determine the content and distribution of uranium areally and stratigraphically in the Sharon Springs member of the Pierre shale of Late Cretaceous age.

A report regarding the uranium content of ground and surface waters in Western Kansas, eastern Colorado, and the Oklahoma panhandle. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.
