Introduction to thermal-mechanical lithosphere models with surface processes

Louis Moresi and Romain Beucher, University of Melbourne

Surface processes including erosion, transport and sedimentation have the potential to strongly influence crustal and lithospheric deformation whether passively, through isostatic response, or more actively by affecting the thermal structure, the potential energy field, and / or the local stress field. Thermo-mechanical models have proven to be valuable tools to understand the processes involved during deformation of the lithosphere. Coupling state of the art thermo-mechanical models to surface processes model is not without challenges. In this webinar we will briefly give an overview of why we think surface processes must be taken into account, how it can be done using numerical models and what are the remaining challenges. The webinar will cover a range of geodynamic contexts and will present some new models of rifts.
