Investigation of Shinarump Channels on Oljetoh Mesa, Arizona - Utah

Description: From to the files: The Shinarump-Moenkopi contact on Oljetoh Mesa in the Monument Valley district, Arizona-Utah, was examined from November 5 to 15, 1951, to determine the location of and the mineralization in Shinarump channels. Twenty-seven distinct channel outcrops were located and examined. Three of these channel outcrops are mineralized and the remaining 24 are barren. Plate I shows the distribution of the Shinarump, the Moenkopi, and the DeChelly member of the Cutler formation; the locati… more

Investigational Drilling, Hoskinnini Mesa

Description: From to the files: To date, all the mineralization seen in the Monument Valley area in the Shinarump formation has been in scour channels. The mineralized rock occurs at or near the bottom of the channel. On Hoskinnini Mesa, all the channels examined to date contain some mineralized material. Channels observed may in some cases contain copper without apparent uranium mineralization; others definitely exhibit copper-uranium mineralization.

Geology of Horse Mesa, Arizona - New Mexico, with Recommendations for Wagon Drilling

Description: Abstract: Horse Mesa is in the Navajo Indian Reservation directly on the Arizona-New Mexico state line. Uranium-vanadium deposits in the Salt Wash sandstone which caps the Mesa are fairly widespread and small tonngges have been shipped from two mines. The deposits lie 60 to 75 feet above the base of the Salt Wash formation and possibly trend northwest parallel to ore trends on King Tutt Mesa, a mile northeast. Carnotite and vanoxite are the principal ore minerals. About 6,000 feet of wagon dril… more

Results of Preliminary Drilling, Red Rock, Arizona

Description: Abstract: Structure drilling under Contract No. AT(05-l)-120 was begun May 13, 1951, and was suspended June 30, 1951, at Red Rock, Arizona with the completion of 12 holes and 2,390.5 feet of drilling. No mineralization was disclosed in the widely spaced holes. The structure and rock composition was found favorable for a potential drilling area.

Reconnaissance of Red Rock Valley, Apache County, Arizona

Description: Abstract: Reconnaissance of Red Rock Valley was begun on December 10, 1953, and completed on February 11, 1954. The mines in the region were investigated and all exposures of Salt Wash were walked. Paleostream directions and alterations of the sandstones were observed and recorded on a base map. No important new mineralization was discovered-and the area is considered to be of no commercial significance if judged by the outcrops alone. However, a vast amount of Salt Wash lies at slight depth di… more

Reconnaissance for Uranium in the Southern Carrizo Mountains, Apache County, Arizona

Description: Purpose: A reconnaissance was conducted during parts of August and September, 1956, of an area about two miles square in the southern Carrizo Mountains where the Permian Cutler formation, including its DeChelly member, and the Triassic Shinarump member of the Chinle formation, are exposed. The purpose was to appraise the uranium potential of the area and to determine the cause of bleaching in the DeChelly. Extensive uranium mineralization in the Salt Wash member of the Morrison formation around… more

Drilling in the Flatirons Locality, Monument Valley, Arizona

Description: From introduction: A subsurface exploration program was undertaken to investigate the concentration of uranium and vanadium in or near the base of the Shinarump member of the Chinle formation in the Flatirons locality, and to develop criteria whereby adjacent unexplored areas could be evaluated as to potential production capacity from study of geological and mineralogical features at the host rook outcrop. An earlier study of the area by C. G. Evensen of the U. S. Atomic Energy Commission had s… more

Historical Review of Uranium-Vanadium Production in the Eastern Carrizo Mountains, San Juan County, New Mexico, and Apache County, Arizona

Description: Introduction: This report is a brief review of the uranium and/or vanadium mining in the eastern Carrizo Mountains, San Juan County, New Mexico and Apache County, Arizona. It was prepared at the request of the Navajo Tribe, the New Mexico Energy and Minerals Department, and the Arizona Bureau of Geology and Mineral Technology. As this report deals only with historical production data, the reader is referred to reports by Blagbrough and Brown (1955), Masters and others (1955), and Stokes (1951, … more

Preliminary Reconnaissance Work in the Rattlesnake Area, Apache County, Arizona

Description: From introduction: The Bluff-Salt Wash contact was mapped on aerial photographs. Mines and prospects were also plotted on the photos. The mines and prospects were studied and a brief description of the mineralization and its occurrence was written. These field notes, which will be given to Hatfield and party, contain data on the presence of carbon and fossil logs, lithology of the gangue rock, sedimentary structures, etc. Regional structure and evidence for igneous activity were also noted.

Reconnaissance Geology of the Southern Muggins Mountains Yuma County, Arizona

Description: Summary and conclusion: More than 4000 feet of Lower Miocene lake sediments were deposited upon a gneissic basement rock, at least locally. The sediments have been gently folded into broad anticlines and synclines and have been cut by high-angle faults with displacements on the order of 100 feet. Both basaltic (?) and acid andesitic lavas have intruded the sediments. A Pleistocene (?) conglomerate unconformably overlies all older exposed rocks. The lake sediments were considered to overlie the … more

Mesaverde Uranium Deposits in the Yale Point-Black Mountain Area, Arizona

Description: Abstract: To date uranium deposits have been confined to a thin sandstone in a zone near the contact of the Middle and Lower Members of the Toreva Formation and as a leach in the Lower Sandstone Member. On a large scale the deposits are apparently restricted to zones of tectonic deformation. Locally mineralization is primarily controlled by small intraformational channels and cross bedding, and is usually associated with carbonaceous material and quartzose sand lenses.

Supplemental and Summary Report on Western Carrizo Uplift and Chuska Mountains Areas of Northern Navajo Indian Reservation Northeastern Arizona

Description: General purpose of survey: During the period 1943 and 1944, the primary purpose was to locate, describe, sample, and generally evaluate the SOM-vanadium mineralization in the western Carrizo Uplift and Chuska Mountains Areas. To this end, the areal geology of the areas, with emphasis on the Salt Wash member of the Morrison formation, was mapped. The triangulation and the laying out of leased plots were supplemental parts of this work. The field work in 1945 was for the purpose of collecting add… more

Geological Investigation of Mexican Cry Mesa, Lukachukai District, Arizona with Diamond Drilling Recommendations

Description: Abstract: The Salt Wash member of the Jurassic Morrison formation of Mexican Cry Mesa, Lukachukai District, Arizona, was examined to determine size, grade, and distribution of contained carnotite deposits and the possibilities of developing reserves by exploratory drilling. Only three occurrences of carnotite-bearing sandstone were found in 17 miles of rim outcrop. Limited drilling is recommended in the vicinity of these exposures.

Uranium-Copper Deposits Near Copper Canyon Navajo Indian Reservation, Arizona

Description: From introduction: During the summer of 1951, Navajos conducted John W. Chester, Russell C. Cutter, and E. V. Reinhardt, Grand Junction Exploration Branch, U. S. Atomic Energy Commission, to a copper deposit in Copper Canyon. Little radioactivity was noted, and no further work was done in the area at that time.
