Abstract

Over the past decades, global geodynamical models have been used to investigate the thermal evolution of terrestrial planets. With the increase of computational power and improvement of numerical techniques, these models have become more complex, and simulations are now able to use a high resolution 3D spherical shell geometry and to account for strongly varying viscosity, as appropriate for mantle materials. In this study we review global 3D geodynamic models that have been used to study the thermal evolution and interior dynamics of Mars. We discuss how these models can be combined with local and global observations to constrain the planet's thermal history. In particular, we use the recent InSight estimates of the crustal thickness, upper mantle structure, and core size to show how these constraints can be combined with 3D geodynamic models to improve our understanding of the interior dynamics, present-day thermal state and temperature variations in the interior of Mars.

Abstract

For the Earth, it is speculated that plate tectonics plays an important role for its long-term habitability at the surface. This convection mechanism transports efficiently surface material by subduction into the planetary interior and allows life to grow and survive due to recycling of nutrients, the stabilization of the climate and the cooling of the deep interior. The latter further helps to maintain the magnetic field that protects the atmosphere from erosion and life from harmful radiation.
