A petrochemical study of the Mount Fubilan Intrusion and associated ore bodies, Papua New Guinea

Creator:: Doucette, John
Abstract:: The Mount Fubilan Intrusion is part of a geologically young hypabyssal stock in the Star Mountains of Papua New Guinea. This stock was mapped as the Ok Tedi Intrusive Complex and divided into four separate bodies: the Mount Fubilan, Sydney Intrusion, Kalgoorlie, and Ningi Intrusions. Hydrothermal fluids caused alteration of...

Crystal Records of the Origin, Evolution, and Thermal Histories of Magmas

Creator:: Bradshaw, Richard W., 1985-
Abstract:: In volcanic systems, magma is generally stored in the shallow crust prior to eruption. The conditions of this storage directly impact whether the magma eventually erupts, or crystallizes within the crust to form a pluton. In this dissertation I present four studies that investigate the storage conditions of a number...

Atomic solid state energy scale applied to novel thin-film solar absorbers

Creator:: Pelatt, Brian D.
Abstract:: The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...

Roles of gas and solid components in the direct nitridation of silicon

Creator:: Pavarajarn, Varong
Abstract:: The factors influencing the direct nitridation of silicon, including the effects of the native oxide layer covering the surface of silicon, the effects of hydrogen contained in the nitridation gas and the catalytic effects of metals added to the raw material silicon, were investigated, using a tubular flow reactor and...

Electronic device and nanolaminate application of amorphous metal thin films

Creator:: Cowell, E. William, III
Abstract:: The objective of this dissertation is to develop amorphous metal thin films (AMTFs) for two-terminal electrical device and nanolaminate applications. Two AMTFs, ZrCuAlNi and TiAl, are investigated in both two-terminal electrical device and nanolaminate applications. Material properties including composition, atomic order, surface morphology, surface potential, and electrical resistivity are explored....

Ecological relation of sympatric steelhead and resident rainbow trout in the Deschutes River, Oregon

Creator:: Zimmerman, Christian E.
Abstract:: Sympatric steelhead and resident rainbow trout (Oncorhynchus mykiss) are known to exist in many rivers throughout the Pacific Rim. Whether sympatric steelhead and resident rainbow trout are polymorphisms within a single gene pool or two reproductively isolated populations has significant implications concerning the study and conservation of this polytypic species....

Deep crustal and mantle inputs to North Sister Volcano, Oregon High Cascade Range

Creator:: Schmidt, Mariek E.
Abstract:: The Central Oregon High Cascade Range is an anomalously mafic segment of the Cascade Arc due to ongoing intra-arc extension, which allows most magmas to traverse the crust without stalling and evolving to more evolved compositions. North Sister, a composite volcano in this arc segment, has produced a seemingly monotonous...

Stable isotope investigation of a hydrothermal alteration system : Butte porphyry copper deposit

Creator:: Zhang, Lihua, 1965-
Abstract:: Typical porphyry-type Cu-Mo mineralization predates and underlies the well-known Main Stage polymetallic veins of the Butte district, Montana. This thesis presents the first systematic study of the isotopic characteristics of the pre-Main Stage K-silicate and sericitic wallrock alteration related to the porphyry Cu-Mo stage. Oxygen and hydrogen isotopic compositions were...

Feeder dikes to the Columbia River flood basalts : underpinnings of a large igneous province

Creator:: Petcovic, Heather L.
Abstract:: Feeder dikes to the Columbia River Basalt Group (CRBG) large igneous province provide a rare opportunity to examine magma transport through the shallow crust during flood basalt eruptions. Over 70% of the CRBG erupted from the Chief Joseph dike swarm, which is exposed across southeastern Washington, eastern Oregon, and western...
