The quantitative characterization of mixing is fundamental to understand whether and how compositional heterogeneities are preserved or destroyed by thermal convection in planetary mantles. Accurate Lagrangian techniques based on particle tracing have been successfully applied to quantify the mixing properties of the Earth’s mantle. Nevertheless, little attention has been devoted to describe mixing in systems in which a strongly temperature-dependent viscosity leads to the formation of a so-called stagnant lid, an immobile rigid upper layer, which does not participate in convection and characterizes all terrestrial bodies other than Earth. The thesis will require the application of existing techniques (Lyapunov exponents) to quantify the mixing properties of such fluids.
