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 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: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer-controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

Although uranium gas first discovered in the Carrizo Mountains area in 1918, the ores were not developed until 1942. They have, however, been mined continuously since that time. Formations in the area range from the Pernian Cutler through the Cretaceous Mancos shale, and all are intruded by a dioritic laccolith and its related dikes. The older structures, which include the Defiance Uplift, the San Juan Basin, and the Four Corners Platform are somewhat disrupted by the effects of the intrusion. A number of mines are described and mineralogical and geochemical studies made are outlined. The primary uranium mineral is unknown, but the chief uranium ore-mineral is the secondary mineral, tyuyamunite. It is concluded that there is at least minor structural control of the ore bodies along sedimentary trends and joints, and that all ore bodies of 500 tons or more are on the Defiance monocline or its extensions. The uranium may have been syngenetic in the sediments, and redistributed by solutions or, more likely, that it rose vertically in hydrothermal solutions from the local intrusive bodies.

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.
