The session topic is interpretation and modelling of the geodynamic processes in the lithosphere-asthenosphere system and the interaction between crust and lithospheric mantle, as well as the importance of these processes for the formation of the discontinuities that we today observe in the crust and mantle. We aim at establishing links between seismological observations and process-oriented modelling studies to better understand the relation between present-day fabrics of the lithosphere and contemporary deformation and ongoing dynamics within the asthenospheric mantle. Methodologically, the contributions will include studies based on application of geochemical, petrological, tectonic and geophysical (seismic, thermal, gravity, electro-magnetic) methods with emphasis on integrated interpretations.

We invite, in particular multidisciplinary, contributions which focus on the structure, deformation and evolution of the continental crust and upper mantle and on the nature of mantle discontinuities. The latter include, but are not limited to, the mid-lithosphere discontinuity (MLD), the lithosphere-asthenosphere boundary (LAB), and the mantle transition zone, as imaged by various seismological techniques and interpreted with interdisciplinary approaches. Papers with focus on the structure of the crust and the nature of the Moho are also welcome.
