Detailed investigation of the Boss Mountain molybdenite deposits, which are on the northeast slope of Takomkane Mountain approximately 35 miles north-northeast of 100 Mile House, British Columbia, was undertaken to determine the origin of the deposits, controls of mineralization, effects of mineralization on the host rock, origin of the breccia bodies, and the relationship of these features to the Boss Mountain Stock. The deposits occur in granodiorite and porphyritic biotite granodiorite phases of the composite Takomkane Batholith near an epizonal Cretaceous quartz monzonite porphyry body, the Boss Mountain Stock. Molybdenite occurs in economic concentrations in two classes of deposits: 1) Breccia Deposits, which include fracture zones, and 2) Vein Deposits, which include both single and multiple systems. The sequence of ore formation, which includes rhyolite porphyry and rhyolite dyke emplacement, breccia formation, fracture development, mineralization, and alteration, is directly related to the oscillatory emplacement of the Boss Mountain Stock. The Boss Breccias, including Phase I Breccia, Quartz Breccia, and Phase III Breccia, were formed by pulsating magmatic activity acting on an irregularity on the side of the magma chamber (Boss Mountain Stock). The rock above this irregularity was fractured by magmatic advances. Withdrawal of magmatic pressure permitted collapse of the overlying fractured rock forming breccia bodies. Rhyolite porphyry dykes, apophyses of the Boss Mountain Stock, preceded and accompanied Phase I Breccia formation. Non-porphyritic rhyolite dykes cut Phase I Breccia and have been engulfed by later breccia phases. Four stages of rock alteration genetically related to the deposits, including (in chronological order): Stage 1, garnet-hornblende Stage 2, biotite; Stage 3, microperthite-chlorite-sericite; and. Stage k, chlorite-talc, have been identified and delineated. Stage 1 formed in mylonite zones around the Boss Mountain Stock, Stages 2 and 3 around centres of mineralization and Stage H- occurs in and near shear zones. Five periods of fracture development, each of which contains quartz veins of unique mineralogy and characteristics, were interspersed with breccia formation, alteration and mineralization. Mineralization accompanied breccia formation and fracture development. Molybdenite was introduced, during three separate periods of mineralization, two of which were separated by a barren stage that produced a complex mineral assemblage. Pyrite accompanies all stages of mineralization. Pleistocene (?) alkali basalt dykes related to Takomkane Volcano, which forms the twin summits of Takomkane Mountain, cut all rocks and ore structures. The volcanic rocks of the volcano contain xenoliths of granodiorite, glassy black augit and peridotite. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

as one of three explanations of a prominenttine delay in the 6.5 km/s branch of their seismic refraction survey in the Rocky Mountain Trench, Eennett et al (1975) suggested a high-angle crustal fault crossing the trench near Radium. If the density contrast between basement and cover rocks is 0.1 g/cm3, a gravity anomaly of approximately 18 mgal should be observed. To test the fault hypothesis, a gravity survey has been carried out in and adjacent to the trench in the Radium area. The resultant data are not consistent with the proposed fault model. The principal feature of the data is a pronounced low which coincides with the trench throughout the survey area. The low is due to Cenozoic fill and interpretation by two-dimensional modeling indicates the thickness of fill is about 550 m to the north and 420 m to the south of Radium. An analysis has also been performed of the shear-wave data recorded during the seismic survey of Bennett et al (1975). Although the quality of the S save data is poor, they show consistent behavior with the P save data. There is weak evidence suggesting a basement refractor velocity of 3.5 km/s and a Moho refractor velocity of 4.2-4.5 km/s. The corresponding Poisscn's ratios are 0.30 and 0.28-0.32. To determine maximum and minimum depth limits to the Hcho allowed by the seismic data, an extremal analysis was performed on both the P and S wave record sections. From the P wave data, the limits on crustal thickness beneath the Rocky Mountain Trench are 52 km and 60 km; from the S wave data, the limits are 47 km and 59 km. Is a result of these additional studies, the tao alternative hypotheses of Bennett et al (1975) to explain the seismic data must be reconsidered. These are (1) the existence of a crustal low velocity zone and (2) a major deformation of the basement and overlying rocks due to the trench being an ancient zone of weakness which coincides with the western limit of the continental Precambrian craton. As reflections from the top of the low velocity zone are not observed by Bennett et al (1975), the second alternative is preferred. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The Black Mountain phase of the Mimbres Mogollon cultural tradition, dating from around A.D. 1150 through A.D. 1300, is perhaps the most poorly understood time period of the entire Mimbres sequence. During that time, people inhabiting the Mimbres Valley of southwestern New Mexico adopted new ceramic sequences, ceased producing Black-on-white pottery, adopted new architectural styles, and possibly changed mortuary patterns. These changes have been interpreted in a multitude of ways that can be reduced to models of continuity and discontinuity. Unfortunately, these models and interpretations rest on a very limited set of data that comes largely from three moderately tested Black Mountain phase sites in the Mimbres Valley proper: Montoya, Old Town, and Walsh. Thus, arguments for or against either model based on the presence of absence of particular traits are necessarily limited by the modest data from these three sites. It was in this context of opposing interpretations that other aspects of the life ways of Black Mountain phase peoples were analyzed. Specifically, I look at the ways lithic and ceramic technologies were organized to assess if the changes that occurred during the Black Mountain phase also represent changes in the ways social systems were organized. I believe that while certain aspects of material culture such as shifts in ceramic or architectural style are easily changed whereas the social mechanisms responsible for their production are more resistant. The results of these analyses demonstrate that there are more similarities than differences with respect to the manner in which technologies were organized during the time periods traditionally accepted as representing “Mimbres” manifestations and the Black Mountain phase. Thus, the social mechanisms dictating the processes of production, distribution, transmission, and reproduction appear to be similar from the Pithouse periods through the Black Mountain phase. This research adds to the growing body of evidence that suggests continuity between the Classic period inhabitants of the Mimbres area and later Black Mountain phase peoples. / text

Approved for public release, distribution is unlimited / The unique combination of thin air, freezing temperatures, and mountainous terrain that forms the high altitude environment has resisted advances in military technology for centuries. The emergence of precision warfare has altered the nature of warfare on most of the world's surface, yet has not significantly changed the conduct of ground combat at high altitude. The tactics that lead to victory on the high altitude battlefield have remained constant over time. This thesis examines the impact of the high altitude environment on soldiers, their weapons, and military operations, and identifies the lessons of the 1999 Kargil Conflict that are relevant to future high altitude combat. Combat at altitudes approaching 18,000 feet (5,485 m) above sea level between India and Pakistan at Kargil illustrates the timeless nature of high altitude warfare. U.S. combat experiences in the mountains of Afghanistan in 2002 parallel those of the combatants at Kargil despite the overwhelming technological advantage of U.S. forces. Trained and wellequipped light infantry is the only force capable of decisive maneuver in mountainous terrain. Heavy volumes of responsive firepower, in concert with bold maneuver, determine victory. Artillery, rather than air power, remains the preferred source of firepower to support ground maneuver. / Captain, United States Army

The study of the subsurface flow and distribution of water is critical to the evaluation of the unsaturated zone for a potential geologic high-level radioactive waste repository. This site is located at Yucca Mountain, Nevada in the northern Mojave Desert. and was chosen on the basis of its low precipitation, deep unsaturated zone, and layered volcanic rocks providing the potential for natural hydraulic barriers to reduce the downward percolation of water through the waste storage area. The detailed characterization of hydrologic properties is necessary to evaluate the mechanisms responsible for the distribution and flow of water in the unsaturated zone. Analyses in this study have provided detailed hydrogeologic units with unique hydrologic properties and hydraulic parameters. Porosity was determined to be a useful physical property for predicting hydraulic parameters, as it relates to the largescale deterministic processes that created the volcanic rocks. The detailed property dataset, along with field measurements of moisture status, temperature, and chemistry, were used to evaluate the potential for lateral diversion in the rocks above the potential repository. It was determined that lateral diversion is a small-scale process in this natural system. On the basis of analyses performed in this study, it is suggested that large-scale diversion is not likely to occur at this site. This mechanism should not, therefore, be relied upon to perform as a natural hydraulic barrier to flow reducing percolation through the unsaturated zone. / Graduation date: 2002
