I am an MSc student working under the supervision of Thomas Stachel and Graham Pearson. My project is done in collaboration with De Beers Group and aims to provide a detailed examination of both mineral inclusions and their host diamonds from the former Snap Lake Mine.  Snap Lake kimberlite dike is located on the southern Slave Craton, which is poorly studied with respect to its mantle root and diamond content in comparison to the Lac de Gras area of the central Slave Craton.  I plan to conduct a detailed examination of the mineral inclusion content in a representative sample of over 100 diamonds from the Snap Lake dike, using electron microprobe (major elements) and laser ablation IC-MS (trace elements) analyses.  From these data I aim to reconstruct both the mineralogy and geochemistry of the diamond substrate beneath Snap Lake and to determine specific pressure-temperature conditions of diamond formation.  The diamonds will be sectioned and polished to produce plates suitable for d13C, d15N and N-content analyses along core-rim transects via ion microprobe. These data will provide constraints on the characteristics of the diamond-forming fluid.    My BSc thesis, which was also completed here at the University of Alberta, involved measuring nitrogen content and aggregation state using Fourier Transform Infrared (FTIR) spectroscopy, and the stable isotope compositions (Carbon and Nitrogen) using multi-collector ion microprobe (MC-SIMS) on sulphide inclusion-bearing diamonds from Victor Mine, Ontario.
