The course aims to understand mechanical behavior (rheology) of Earth materials exposed to various environmental conditions (e.g. pressure, temperature, force-stress, deformation rate) as a key to understand the large-scale processes leading to redistribution of large portions of Earth`s crust and mantle. A physical response of Earth materials to deformation will be explored throught the micro-scale study of deformation microstructures and crystal plasticity. Particular examples of various rock microstructures will be demonstrated during the practical part of the course. In addition, the course aims to clarify physical background of intracrystalline and intercrystalline deformation and recrystallization processes occurring in most common Earth materials. |
