The petrography and mineral chemistry of melt-intruded mantle xenoliths from the Chidliak kimberlite field, Baffin Island, Canada
DownloadFall 2021
The nature of kimberlitic melts at mantle depths and their interaction with mantle wall-rocks is poorly constrained. This is due to the scarcity of mantle xenoliths and xenocrysts that have preserved this interaction without disaggregating during their transport to Earth’s surface. This thesis...

The Quandary of the Sask Craton: Origin and Evolution of the Lithospheric Mantle beneath the Sask Craton
DownloadFall 2018
Mantle xenoliths from the Cretaceous (~106 to ~95 Ma) kimberlites at Fort à la Corne (FALC) present a unique opportunity to study the lithospheric mantle beneath the newly recognised Sask Craton. The Sask Craton, a small terrane with Archean (3.2 - 2.5 Ga) crustal ages, is enclosed in the...
