Geodynamics

Geodynamics refers to the processes by which mantle convection shapes and reshapes the Earth and other rocky planets. Its study includes plate tectonics, volcanism, the chemistry of lava and volcanic rocks, gravity and geomagnetic anomalies as well as seismic investigations into the structure of the mantle.

    How the mass of super-Earths affects mantle convection is a key question for understanding rocky exoplanet structure and thermal dynamics. New material models based on ab initio mineral calculations characterize convection, with implications for magnetism, planetary cooling, atmospheric composition and habitability.
