The deep crust represents one of the least observable and most challenging domains of the Earth's interior. Its physical and chemical properties exert a fundamental control on the mechanical behaviour of the lithosphere, the localization of deformation, (i.e., shear zone development, occurrence of seismicity) and the transfer of heat and mass between the crust and the mantle. However, its depth and limited exposure have long restricted direct constraints on its composition, structure, and dynamics. In recent years, significant advances in geophysical imaging and analytical techniques have profoundly improved our understanding of the deep crust, providing new constraints that are now driving the formulation of updated evolutionary models for this critical horizon. This session seeks to integrate the latest geophysical, experimental, geochemical, and structural observations into these models, advancing our understanding of deep crustal dynamics and evolution.
