Innovative Solid Earth Modelling

Taras Gerya, ETH Zurich, Switzerland

Abstract:

Modern gross challenges in Solid Earth Modelling are: (i) creating high-resolution realistic 3D numerical models applicable to nature, and (ii) obtaining a rigorous understanding of geodynamic and planetary processes and the key physical parameters controlling them. We developed a family of finite-difference, marker-in-cell codes which can handle visco-elasto-plastic rheology, mineralogical phase changes, free surface and self-gravitation. With this new tools we created a number of predictive numerical models for various geodynamic and planetary processes, such as mid-ocean rift formation, oceanic and oceanic-continental subduction, continental collision, slab breakoff, intrusion emplacement into the crust, planetary accretion and metallic core formation.
