Trans-lithospheric plumbing systems provide a framework for understanding how melts are generated, transported, modified and stored across the mantle-crust continuum, linking deep magmatic processes to their volcanic and plutonic expressions. The architecture and evolution of these systems control how mantle-derived melts interact with the lithosphere, undergo differentiation and mixing, and ultimately feed crustal reservoirs and volcanic systems, including their metal endowment. Investigating their deep roots and connectivity is therefore essential for reconstructing the spatial and temporal evolution of magmatism and for understanding the relationships between igneous processes in the mantle and the crust, as well as the interaction of volcanic systems with the atmosphere.
This session thus invites contributions addressing the architecture, dynamics and evolution of trans-lithospheric active or fossil plumbing systems from mantle melting to magma transport, crustal storage, differentiation and eruption. We particularly welcome multidisciplinary studies integrating geophysical, geochemical, petrological, structural or numerical modelling perspectives that investigate the connections between deep and shallow magmatic processes and provide new perspectives on the volcano-plutonic link and associated volcano hazards.
