The physical and geochemical characteristics of diamonds from the Artemisia Kimberlite (Northern Slave Craton, Nunavut, Canada) and the micro-/macro-diamond relationship
DownloadFall 2011
This thesis presents the results of a study on diamonds from the Artemisia kimberlite, Nunavut, Canada. This study integrates the isotopic, chemical and physical characteristics of the diamonds in an attempt to provide insight into the nature of the micro-/macro-diamond genetic relationship, and...

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 origin and evolution of eclogite xenoliths and associated diamonds from the Jericho kimberlite, northern Slave craton, Canada: an integrated petrological, geochemical and isotopic study
DownloadFall 2011
Diamond-bearing eclogite xenoliths are relatively rare but provide insight into the composition and evolution of the cratonic lithospheric mantle and also insight into the diamond formation process. The major-, trace-element and Sr-Pb-O-isotope compositions of both high- and low-MgO diamond...

Fall 2009
The oxidation state, reflected in the oxygen fugacity (fO2), of the lithospheric mantle is both laterally and vertically heterogeneous. Depth-fO2 profiles from kimberlite-borne peridotitic mantle xenoliths from the Bultfontein kimberlite, Kimberley, South Africa and the A154-N and A154-S...

Gahcho Kué is a diamond mine in the Northwest Territories of Canada that opened in 2016. This is the first study into the morphology, N systematics, and stable isotope (C and N) composition of the Gahcho Kué diamonds, and the mineral chemistry of the associated inclusions. The resulting data are...

Rockbursts have been a hazard for mining operations since underground mining first came into practice; the consequences they present to mining personnel and machinery can be fatal and costly. Underground mining in Northern Canada has presented the opportunity to study the bursting properties of...

Mineral inclusions in diamonds from Chidliak (Nunavut, Canada): constraining the diamond substrates
DownloadFall 2018
The Chidliak kimberlite pipe is located on the Hall Peninsula on Baffin Island in Nunavut. The first kimberlite in Chidliak was discovered in 2008. Previous studies (e.g., Hogberg et al., 2016) on Chidliak inclusion-free diamonds have suggested that 1) two diamond growth stages are recorded by...
