Research Dissertation: The Magmatic-Hydrothermal Behaviour of Trace and Ore Elements Within Intermediate-Evolved Igneous Systems
My current research focuses on improving our understanding of volatile recycling at subduction zones through analysis of primitive rocks from Kamchatka.
Our project involves the in-situ analysis (EPMA, LA-ICP-MS, SIMS) of minerals, glasses, and melt inclusions to reveal systematic variations in the concentrations of H2O, C, F, Cl, S, B, and other volatile trace elements cycled through subduction zones.
My PhD research assimilated complimentary information derived from experimental petrology (IHPV) and natural volcanic samples (Augustine volcano, AK) to better constrain the fluid-crystal-melt partitioning behaviour and fluid transport of trace and ore elements in intermediate-evolved magmatic systems, and their associated hydrothermal ore deposits (Spirit Lake Pluton/Margaret Cu-Mo porphyry deposit, Mt. St. Helens, WA).
