Will Siva-Jothy MSc| DERTS Trainees

Will defended his MSc in February 2020.

My research involves examination of mineral inclusions within diamonds obtained from the recently opened Gacho Kue mine, within the Slave Craton. Samples have been provided by DeBeers. The aim of my project is to identify the major element chemistry, and how it relates to the nitrogen content and stable isotope data of the enclosing diamond, with olivine inclusions being prioritised, as they enable temperature estimates for the initial conditions. Prior to starting this program, I assisted in a research project at the University of Leeds, as an undergraduate, examining the Sr and Nd signatures in clinopyroxene phenocrysts from the Eifel field. In the future, I plan to apply the techniques, expertise and approaches I will develop during this program to examine formation processes from other diamond-bearing localities.
