Additional feeds to the subduction channel correspond to overriding plate fragments that are removed by subduction erosion. Understanding the diagenetic and metamorphic transformations, and mechanical behaviour of the fluid-saturated subducting material is critical, because they govern processes such as inter-plate friction, hydrofracturing or basal erosion. Pore fluids have also a major influence on heat transfer, and control in turn the location of the seismogenic zone and the amount of co-seismic slip. At greater depths, the dehydration and partial melting of subducted sediments strongly affects the composition of volcanic arc magmas. We welcome here geological, geophysical and geochemical observations and models concerning different aspects of fluid flux, mass transfer and energy release in subduction zones. The objective is to better understand the processes governing margin evolution that occur from the trench to the mantle wedge at different spatial and temporal scales.
