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...

This research was motivated by the common recovery of yellow diamonds from kimberlites at Chidliak, Ekati and Qilalugaq in recent years, giving Canada the potential to become the new major source of fancy yellow diamonds. This thesis focuses on the analysis of yellow diamonds recovered from the...

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...

The composition of the lithospheric mantle beneath the Karowe Mine and its associated diamond sources in north-eastern Botswana
DownloadSpring 2019
This study presents the first comprehensive data on the recently developed Karowe diamond mine from the Orapa kimberlite cluster, which hosts mines such as Orapa, Damtshaa, and Letlhakane. The objectives of the study were to establish the compositional characteristics of the lithospheric mantle...

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...

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...
