An experimental study on a minette and its associated mica-clinopyroxenite xenolith from the Milk River area, southern Alberta, Canada
DownloadFall 2012
Buhlmann et al. (2000) studied the minettes and xenoliths from southern Alberta, Canada. They hypothesized that the minettes were derived from a source containing phlogopite + clinopyroxene at pressures ≥ 1.7 GPa. To test this hypothesis, we investigated 1) the liquidus mineralogy of a primitive...

Phlogopite, an alkali-rich and water-bearing mineral, is a common phase in the Earth’s upper mantle. Its breakdown could generate melts or stabilize fluids that will metasomatize mantle rocks. To date, the effect of CO2 on phlogopite stability remains unconstrained. To evaluate the stability of...

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...

Exploration methods for diamonds often employ the geochemistry of single minerals to identify deposits. Due to the scarcity of diamonds, exploration practices use minerals known as “kimberlite indicator minerals” as these minerals are typically more abundant than diamond and may have equilibrated...
