Geodynamicists, structural geologists, petrologists and mineralogists are driven by the same essential curiosity about processes affecting the Earth’s crust and lithosphere, and use different tools to understand these processes. If properly quantified and interpreted, fabrics and microstructures in rocks provide fundamental constraints on lithospheric evolution. It has been recognized that deformation and mineral reactions are closely linked. The smaller the scale considered, the more heterogeneous an apparently uniform rock sample is! This heterogeneity, that we must account for, is not only characterized by variation in chemical composition but also in mechanical properties of different mineral phases. During the past years, the coupling of the two processes and its quantification has received an increasing attention. New quantification approaches and new experiments have been developed. Moreover, the increased use of numerical models in computational geomechanics has brought important insights in the understanding of these complex processes. Here, we encourage presentations focused on the relationship between metamorphic processes and deformation at all scales to discuss (1) how and when stress/pressure variations can be preserved at geological timescales, (2) quantification approaches for the coupled systems, (3) impact of volumetric changes during phase transitions on geodynamic reconstructions or (4) simply the conventional metamorphic contributions where the mechanical feedback to the metamorphic reactions seems to be irrelevant. Contributions from natural samples, experiments, as well as theoretical and modelling studies are welcome.

Keynote: Marcello Campione (University Milan, Italy) “Friction from the standpoint of single atoms: How nanoscale mineral topography drives macroscale seismicity”.
