Following the wish of the students, this class will be entirely in English or German
Most geo-processes invoke the redistribution of energy and matter. Prominent examples for such processes, among others, are mantle convection, the formation of hydrothermal ore deposits, or the formation and dissociation of gas hydrate processes. Further, in active regions such as subduction zones, energy and fluids are transferred between plates. The spatial distribution of thermal material properties strongly influences such processes and therefore the thermal structure of the earth. Heat transport is quantitative described with partial differential equations of the diffusion type, and therefore a process, which can be simulated efficiently employing numerical methods such as finite difference or finite element simulations. Thermal gradients, temperatures, and heat transport also affect deformation, as they determine the rheological behaviour of the subsurface. Circulation of aqueous fluids and especially through faults leads to efficient redistribution of heat in the brittle crust, thus playing an important role e.g. in hydrothermal ore deposit formation and the accumulation of hydrocarbons including gas hydrate systems.
