My research to date has primarily involved studying mafic layered intrusions (MLI) and in particular, late-stage magmatic processes that occur during their crystallization. MLI are excellent natural laboratories for understanding important petrologic precepts, especially in closed-system intrusions where slow-cooling with little interaction can be achieved.
My BSc research, also at UBC, focused on symplectites (late-stage reactive microstructures) in the Kiglapait layered intrusion (Labrador, Canada) in order to decipher their compositional and textural relationships and to tease out the chemical evolution of interstitial liquids.
My MSc project aims to establish the variability in lead isotopic compositions of plagioclase from the ~56 Ma Skaergaard intrusion (E. Greenland) by laser ablation ICP-MS. The trace element and Pb isotope systematics will be used to constrain the parent magma and mantle source compositions and to determine the extent of crustal contamination prior to emplacement. Given the Skaergaard intrusion cooled from a single, homogeneous magma body, it is an ideal testing ground for basic petrologic processes - making it one of the world's most influential layered intrusion.
