Welcome to the Macquarie’s Geophysics and Geodynamics Group (MG3) website. The MG3 is based in the Department of Earth and Planetary Sciences at Macquarie University and focuses on understanding the nature and evolution of our planet, as well as other terrestrial planets and moons. We study a wide variety of geophysical and geodynamic processes, ranging from shallow geothermal studies to the deep dynamics of the Earth’s mantle (see our About Us tab!). We are particularly interested in understanding the Earth in a holistic manner, and therefore our research is characterised by a strong multidisciplinary approach. In our studies, we combine concepts/data from a number of disciplines, such as Mineral Physics, Geochemistry, Numerical Modelling, Thermodynamics, Inversion Theory, etc.

We are liaised with the Australian Research Council’s Centre of Excellence for Core to Crust Fluid Systems (CCFS) and the Australian Research Council’s National Key Centre GEMOC (see links to the right). We also have a long list of formal collaborators (see our About Us tab for details) in Australia and overseas. The research questions that our staff and students address include, but are not limited to:

  • Multi-observable probabilistic inversion for the thermochemical structure of the Earth.
  • Multi-phase reactive flow in the Earth’s mantle.
  • Mantle convection and episodic overturns over Earth’s history.
  • The lithospheric structure of Venus.
  • Finite-frequency surface wave tomography.
  • Ambient noise surface wave tomography.
  • Long-term seismicity and fault strength of plate boundaries.
  • Subduction initiation at the Hjort Trench near Macquarie Island.
  • Geothermal modelling and temperature state of the crust in Australia.
  • Thermal and compositional evolution of the oceanic lithosphere.
