My research and that of my students focus on understanding deposit scale to camp scale deformation processes involved in the genesis and subsequent deformation of ore deposits and their host rocks. Ore deposits generally form in tectonically active environments. Tectonic structures, such as faults, directly control the genesis of ore deposits because they act as conduits for the flow and migration of hydrothermal fluids. Post-depositional deformation can subsequently affect the geometry, continuity, mineralogy, and metal grade of ore deposits. Rock units hosting ore deposits are affected by the deformation events responsible for the formation and/or subsequent modification of the deposits. Knowing how host rocks of ore deposits behaved during deformation is key to understanding how deposits formed and were subsequently deformed.
