Primary Sedimentary Trend Indicators as Applied to Ore Finding in the Carrizo Mountains, Arizona and New Mexico

Description: Abstract: Field and laboratory study of primary sedimentary features of the Salt Wash sandstone was undertaken to learn if these structures can be of use in finding hidden deposits of ore and also if they have influenced the localization of either individual ore deposits or larger mineralized districts.

Preliminary Reconnaissance of the Dripping Spring Quartzite Formation in Gila and Pinal Counties, Arizona

Description: Abstract: A four-week reconnaissance of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, was undertaken in March and April, 1953, to inspect accessible outcrops of Dripping Spring quartzite, a pre-Cambrian formation which has lately attracted the interest of the Atomic Energy Commission by the discovery of two separate occurrences of uranium mineralization. Although no new deposits were found during the field work, a more thorough examination of the quartzite seems warranted. Recommendations for further prospecting by airborne and ground methods are presented in this report, and are based largely on observations made during the brief visit.

Preliminary Report on Uranium-Bearing Deposits in Mohave County, Arizona

Description: Abstract: Preliminary studies of the Wallapai Mining District and selected properties in the Maynard and Greenwood Mining Districts, Mohave County, Arizona, from January 8 to March 8, 1953, were made to determine the extent of uranium mineralization. All of the uranium properties examined are of the vein type and are believed to be of mesothermal origin. Brecciation and porosity of the veins appear to be controlling factors in the concentration of uranium minerals from the ore-bearing solutions. Although the uranium minerals present in these districts have not been specifically identified, they appear to be mostly primary with very minor occurrences of secondary products. One exception is the State mine in the Greenwood District, where secondary minerals predominate.

Preliminary Report of Reconnaissance in the Cameron Area, Arizona

Description: Introduction: A radiometric airborne reconnaissance of the Cameron, Arizona, district was conducted in the late fall of 1952 and early winter of 1953. Flying was carried out under the direction of the Salt Lake Exploration Branch of the Atomic Energy Commission, Division of Raw Materials. Airborne equipment and ground personnel were provided through the Technical Services Branch of the Grand Junction Exploration Division.

Uranium Occurrences in Wilson Creek Area, Gila County, Arizona

Description: Abstract: The Wilson Creek Area, in northern Gila Cointy, is about 10 miles southeast of Young, Arizona, along the east side of Cherry Creek. Four claims covering concentrations of uranium mineralization in the Dripping Spring Formation are owned by the American Asbestos Cement Company. The claims are located in typical plateau-type topography, with flat mesa* and nearly vertical canyon walls. The bedded zones of uranium mineralization are exposed in the Dripping Spring Quartzite near the bottom of the canyons. It is suggested that the mineralized beds may have spatial relationship to the bottom of the Mescal limestone and to the bottom of a thick zone in the upper member of the quart site. Two of the four bedded deposits occur in *crackled" beds. One mineralized fracture was noted. The uranium mineral, meta-torbernite, has formed in tiny vugs in the quart site and is also intergrown with the iron oxide coating on the quart site surfaces. Associated minerals are minor and consist of chalcopyrite magnetite and chalcocite.
