THE GEOCHEMICAL BEHAVIOR OF SCANDIUM DURING FRACTIONAL CRYSTALLIZATION AND IMPLICATIONS FOR ORE FORMATION
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, ...
Petrologic, Geochemical, and Spectral Characteristics of Oxidized Planetary Differentiation
Meteorites provide evidence that planetary formation occurred across a wide range of oxidation environments in the early Solar System. While the process of differentiation for many reduced, oxygen-poor assemblages has been ...
Petrologic and geochronologic constraints on the thermal and structural evolution of paleo-subduction interfaces
In subduction zones, the interface between the downgoing slab and overriding plate controls a number of important dynamic processes. Both the rheologic behavior and thermal structure of the interface influence fluid release ...
DYNAMIC MELT PROCESSES IN THE LITHOSPHERES OF MARS AND IO
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
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 ...
