Interim Report on Geologic Investigations in the Monument Valley Area, Arizona

Description: From abstract: The Geological Survey has completed a program of uranium investigation and geologic mapping in the Monument Valley area, Apache and Navajo Counties, Ariz. The program, undertaken on behalf of the 'Atomic Energy Commission, had two principal objectives. The first was to establish prospecting guides for uranium ore deposits. The second objective was to appraise the relative favorableness of formations and areas for the occurrence of uranium deposits in order to select localities that deserve further exploration.

Structural Analysis of a Mechanized LHD Trench Undercut Caving System

Description: Abstract: This U. S. Bureau of Mines (USBM) report presents results of stress analyses and field observations to investigate the effects of elevated trench drifts on the structural stability of rock mass zones surrounding a production draw drift in a mine utilizing a mechanized load-haul-dump (LHD) trench undercut panel caving system. A two-dimensional boundary-element mine stress model was developed to predict the locations and extent of damaged rock mass zones surrounding draw drifts where adjacent, parallel trench drifts are either elevated or not elevated above the LHD production draw drift level. A Mohr-Coulomb shear-failure criterion was obtained directly from in situ borehole shear test data. Hoek-Brown shear-failure parameter values were computed from borehole-shear and triaxial test data. A procedure is described to estimate these parameters when a rock mass rating (RMR) value and triaxial data on intact samples exist, and no borehole shear test data exist. Results indicate that trench drifts, elevated to the level equal to the height of the LHD production draw drift, would not minimize material damage nor significantly enhance the stability of rib and crown pillar zones surrounding production draw drifts in the mechanized LHD trench undercut caving panel investigated at this mine.

Mineral Resources of the San Carlos Indian Reservation, Arizona

Description: From abstract: At the request of the Council of the San Carlos Apache Tribe the U. S. Geological Survey entered into a cooperative agreement calling for a brief reconnaissance study to determine, as far as practical, the mineral potential of the San Carlos Indian Reservation. Five months of field work was done during the winter and spring of 1952-53. About 30 percent of the reservation is covered by alluvial deposits of late Tertiary, Pleistocene, and Recent age, and another 60 percent is covered by volcanic rocks of Tertiary and perhaps Pleistocene age. These rocks are younger than the major epochs of metallization in southeastern Arizona. The remainder of the area is underlain by pre-Cambrian and Paleozoic sedimentary rocks, pre-Cambrian granite, and pre-Devonian diabase.

Preliminary Summary of Reconnaissance for Uranium in Arizona

Description: From introduction: A reconnaissance of Arizona uranium deposits was started in October 1950 and continued through April 1951. A total of six man--months was spent by H. C. Granger, E. P. Kaiser, and J. W. Adams. About 40 properties were examined and, of these, six were mapped by plane-table method and six were sketch-mapped. This reconnaissance was not intended as a complete evaluation of all Arizona deposits; other areas and occurrences were not examined during the investigations and are not discussed in this report.

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. In October 1951, the same group of Navajos reported the discovery of uranium ore in another portion of the same area. The site was visited by Cutter who noted that an excavation made by the Navajos had disclosed a 3-foot thickness of low-grade uranium ore. In November 1951, Cutter again visited the area and observed that the Navajos had opened a 5-foot face of good ore.

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 additional and supplemental geological data in order to complete the record and to calculate the ore reserves of the areas.

Ground-Water Monitoring in the Tucson Copper Mining District

Description: Abstract: Ground-water and tailings pond monitoring in the Upper Santa Cruz Basin Mines Task Force's Special Studies Area has been performed to determine the nature and extent of aquifer contamination from copper tailings pond's recharge in the basin. A monitoring program for each of three mining areas (Mines A, B, and D) was developed. Analysis of data shows that recharge from Mine A's ponds has caused increased hardness, sulfate and total dissolved solids in local ground water. However, pumpage in the area has controlled most of the water's movement. Pond recharge from Mine B has led to similar conditions, and the degraded water is moving towards a local public-supply well. Pumpage from Mine D's interceptor wells is controlling some, but not all, of the movement of recharge seepage from Mine D's ponds. Recommendations include the need for enhanced monitoring programs at each current mine site, development of a monitoring program for Mine C's area, development of water budgets for all mines, investigation of tailings pond compaction and sliming, establishment of mine closure plans for containment of recharged pond water, and the need for additional interceptor wells in several locations.

A Preliminary Investigation of Triassic Rocks in the Lukachukai Mountains, Arizona

Description: Abstract: During the summer of 1955, two test holes were drilled into the Triassic Chinle Formation in the Lukachukai Mountains near Cove, Arizona, to obtain geologic information. Brief airborne and ground reconnaissance was made of Triassic outcrops near Cove. No anomalous radioactivity was found in the test holes, but chemical tests showed concentrations of heavy metals in conglomerate lenses in the Chinle Formation. Channel sandstones in the middle part of the Petrified Forest Member appear to be the most favorable for mineralization. The Shinarump Member, here underlain by a permeable unit, and occurring at depths greater than 500 feet, appears less promising for uranium exploration.
