This PhD project is entitled “Diamonds and their syngenetic inclusions from the Koffiefontein mine, South Africa.” This research aims to identify the role of ultra-deep diamonds and their relationship to high value diamonds at the Koffiefontein mine, with ferropericlase being the main mineral of interest. This will be achieved through characterisation of the host diamond with nitrogen aggregation state and carbon isotopes, as well as chemical classification of the included silicate, oxide, and sulphide minerals on the microprobe. Lastly, Re-Os dating of the sulphides will provide further insights on the timing for the formation of the diamonds within the Koffiefontein pipe. This research marks the first in-depth study of the ultra-deep diamonds and the ferropericlase inclusions at Koffiefontein since they were first described in the early 80s.

Funding for this project is provided by the South African National Research Foundation (NRF) through the Doctoral Scholarship Abroad programme.
