RE-OS AND OXYGEN SYSTEMATICS OF VARIABLY ALTERED ULTRAMAFIC ROCKS, NORTH CAROLINA
(2020)
This study focuses on the origin and modification of six ultramafic bodies located in the Blue Ridge Province of North Carolina. The bodies consist mainly of harzburgites and dunites with associated chromites. Some of the ...
Planetary Seismology using Single-Station and Small-Aperture Arrays: Implications for Mars and Ocean Worlds
(2020)
Studying geophysical station deployment on Earth is essential preparation for future geophysical experiments elsewhere in the solar system. Here, I investigated how single-station seismometers and small-aperture seismic ...
Geophysical Exploration of Terrestrial and Lunar Volcanic Fields
(2021)
Planetary analogs are environments representative of current or past conditions on other planetary bodies. My research uses terrestrial volcanic fields as lunar analogs to conduct geophysical studies on the subsurface ...
Characterizing 3-dimensional Melt Distribution and Anisotropic Permeability in Sheared Partially Molten Rocks
(2020)
With increasing shear strain, initially homogeneously distributed melt can segregate into an array of melt-rich bands, flanked by melt-poor regions. To address how the formation of these melt-rich bands affects the transport ...
THE GEOCHEMICAL BEHAVIOR OF SCANDIUM DURING FRACTIONAL CRYSTALLIZATION AND IMPLICATIONS FOR ORE FORMATION
(2020)
Demand for scandium is increasing due to the use of scandium-aluminum alloys in the aerospace and sporting goods industries, and in solid-oxide fuel cells. Scandium deposits are associated with mafic intrusions and laterites, ...
DEFORMATION AND FAILURE OF LUNAR LAVA TUBES
(2021)
Lava tubes are long void spaces left by lava flows. Terrestrial tubes have been extensively studied. Evidence indicates lunar tubes also exist, potentially ideal environments for lunar exploration, habitation, and study. ...
DYNAMIC MELT PROCESSES IN THE LITHOSPHERES OF MARS AND IO
(2020)
The interior structures of planetary bodies beyond the Earth are broadly unknown. Our observational capacity is largely limited to surface imagery from spacecraft. The work presented in this dissertation uses novel modeling ...
CHARACTERIZING THE DURATION, PERIODICITY AND CHEMICAL IMPACT OF FLUID TRANSPORT IN THE SUBDUCTING SLAB: INSIGHTS FROM ISOTOPE GEOCHEMISTRY OF HIGH-PRESSURE METAMORPHOSED OCEANIC CRUST
(2021)
Subduction zones are key loci of geochemical cycling and natural hazards on Earth including large earthquakes and explosive volcanic eruptions. Fluids produced during subduction are thought to play a role in all these ...
Rb-Sr Radiometric Dating of Rocky Planetary Bodies via LA-ICPMS
(2021)
Constraining ages of surface features on rocky objects in the Solar System provides fundamental insights about the flux of impactors through time (including the putative Late Heavy Bombardment), rates of tectonic and ...
