Research

Research group: Volcanoes, Tectonics and Mineral Resources

  • The kinematics, geometry, and mechanics of fault zones, and the influence of existing structures and anisotropies in their development.
  • Quantitative analysis of faults, fault zones, and fractures, particularly with respect to fluid flow, and strength characteristics through time.
  • Fault rock characterisation, with special focus on the development of fault breccias, and their relationship to mineralisation phases and fluid flow.
  • The nature, evolution, and significance of transverse and transfer zones in continental rift systems.
  • Volcanic plumbing systems, including dyke and sill emplacement and the rheology of magmas in the subsurface.
  • Fault/fracture-hosted clastic intrusions and clastic infills, and their implications for conditions during and following faulting.
