A detailed knowledge of the Earth’s physical properties and chemical composition is fundamental in order to shed light on the planet inner workings, and improve our understanding of phenomena such as plate tectonics, mantle convection and glacial isostatic adjustment. The last decades have seen a steady increase in the quality and quantity of various kinds of geophysical data, for example seismic, gravity and electromagnetic observations. A new generation of geophysical models, able to simultaneously satisfy multiple constraints, is necessary to take full advantage of such a diverse dataset.

This session principally focuses on forward and inverse modelling of crust and mantle physical properties and chemical composition. We particularly welcome studies (i) leveraging on a multi-disciplinary approach, using gravity data (e.g. GRACE, GOCE, regional scale dataset), magnetic observations (e.g. Swarm, EMAG2, Chaos, regional scale dataset), seismic measurements, mineral physics constraints and petrological data; (ii) dealing with regional to global scale modelling; (iii) willing to evaluate the impact of the inferred thermo-chemical structure on geodynamic processes.
