Derek’s is currently working on the Chesterfield Fault Zone, which is the one of the largest and most poorly understood structures in the Rae Craton, i.e. the northwestern portion of the Canadian Shield. This research includes regional and detailed geological mapping as well as micro-textural, mineralogical and isotopic studies in order to determine the geologic history of the shear zone. Derek collaborates with the Geological Survey of Canada and has worked with multiple northern communities during his research including Baker Lake, Taloyoak, and Resolute Bay, Nunavut.
