The main objective of Benoit-Michel Saumur's MSc thesis project is to evaluate the origin of serpentinites in the oceanic subduction complex in the northern Dominican Republic. There are three different types of serpentinites in the area; a) massive serpentinites, b) serpentinite melanges containing fragments of blueschist and eclogite, and c) serpentinites along major deformation zones.


After completing MSc in December, 2007, he started a PhD program at the University of Toronto in 2008, then moved to Monash University in Australia to follow his supervisor.
