The Yanacocha Mining District in northern Perú is considered the largest group of
high-sulfidation style epithermal gold deposits in the world. District-scale geologic mapping coupled with detailed 40Ar/39Ar geochronology, geochemistry and petrography establish the volcanic history of the area and analyze the temporal and spatial evolution of volcanism, hypogene advanced...
This thesis presents a detailed seismotectonic investigation of the Himalayan region and the Tibetan plateau as part of project HiCLIMB to explore the state of stress and the kinematics of the world’s largest continental collision zone. Using full regional waveforms for moment tensor inversion, source parameters for 107 earthquakes were...
Catalysis of the racemizationof optically active phenyl
benzenethiolsulfinate, (+)-I, by (a) methylthioacetic acid (II) and (b)
a -methylthio-m-toluic acid (III) has been investigated in aqueous
dioxane and anhydrous acetonitrile at 39.6°C. Added II did not cause
any increase in the rate of racemization of (+)-I in either solvent. In
aqueous...
Western redcedar (Thuja plicata Donn.) is a valuable commercial species found in
the northwestern United States and southwestern Canada. This dissertation includes four
papers focused on wood and stem characteristics of second-growth western redcedar, and
how those characteristics vary within the stem or how they are influenced by cultural
practices....
The ability of Flexibacter columnaris to attach to fish
cells was studied. Four of the five bacterial strains
tested were able to adhere to fish cells derived from four
different fish species. The attachment of these strains
in vitro required magnesium but was not affected by
increasing the incubation temperature...
The Hi-CLIMB seismic experiment (2002-2005) operated 233 sites along an 800-km long north-south array extending from the Himalayan foreland into the Central Tibetan Plateau and a flanking 350x350 km lateral array in southern Tibet and eastern Nepal. Data from the experiment’s second phase (June 2004 to August 2005), when stations...
