Master thesis: Role of variable thermal expansion on the initiation of plate tectonics

Beschreibung:

The problem of the initiation of plate tectonics regards understanding the conditions, which lead to the formation of weak zones (plate boundaries) that serve as nucleation points for the onset of subduction - the process with which tectonic plates sink into the mantle. The creation of such weak zones can be favoured by a positive feedback exerted by the temperature dependence of the coefficient of thermal expansion, which, however, is generally kept constant in plate tectonics models. The thesis work will involve numerical simulations of visco-plastic convection devoted to assess the importance of variable thermal expansivity in controlling the onset of plate tectonics on terrestrial planets.

The student will learn

• how to handle and run a complex 3D convection code (C++) on a cluster
• how to use a visualization tool (IDL) and analyze data
• some basic understanding on planetary physics in particular in planetary dynamics
