Spring 2021
Diamonds, due to their inert and robust nature, encapsulate and preserve minerals, recording the mantle substrate in which they form. Forming in the subcontinental lithospheric mantle over a protracted period, diamonds provide snapshots of craton formation and mantle evolution over much of...

Spring 2009
Natural peridotitic diamonds form in the 'diamond window' (DFW), an area of the upper mantle bounded by temperatures of 900-1400°C and pressures between 4 and 7 GPa. This study has experimentally tested and shown the viability of a hydrous, halide bearing silicate melt as a possible diamond...

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...
