Computational resources have reached a state that allows us to perform 3D spherical mantle convection simulations at full numerical resolution. Crossing this threshold barrier means in particular, that it is possible now for the first time to study the thermal evolution, geotherm, and partitioning of internal (radioactive) and external (core derived) heat in Earth's mantle in global convection models under the dynamic parameter regime appropriate for our planet. We will present early results from global fully resolved mantle convection models at Rayleigh numbers exceeding 10exp9. We will discuss the linkage of these dynamic models to mineralogic mantle models derived from thermodynamic considerations of Gibbs free energy minimisation in order to facilitate direct comparison with tomographic mantle models that aim to constrain the internal mantle temperature structure.
