This teaching module provides an overview of our current understanding of the dynamic forces that drive Earth's
evolution by linking seismic observations and mantle mineral properties with geodynamic processes.
Based on geophysical fundamentals (conservation of energy, mass, and momentum, viscous mantle convection, viscoelastic deformation of the lithosphere, effects of phase transitions), numerical methods will be presented and explained (finite differences, finite elements, and spectral methods) that provide versatile modeling tools to study the non-linearly linked processes of plate tectonics and deep mantle convection. Using available "public domain" software (CIG repository), all participants should become able at the end to solve typical geodynamic problems (e.g. calculation of lithosphere geotherm or of convective mantle heat flow). The module examination consists of a written homework on an assigned numerical problem set (in MATLAB), that has to be solved within 6 weeks after finishing of the course. Successful completion will give 6 ECTS. |
