| Session Description | Subduction zones are the dynamic site of mass and energy exchange between slab and mantle. As the places where Earth’s lithospheric plates sink into the mantle, they are responsible for earthquakes, volcanic eruptions and mineral resources at convergent plate margins. These natural phenomena result from such processes as deep and shallow seismicity, deformation and metamorphism, heat flux and fluid flow, and element enrichment and magmatic activity. Although it has been well established that high- to ultrahigh-pressure metamorphic rocks are the product of subduction-zone metamorphism and that island and marginal arc volcanic rocks are the product of subduction-zone magmatism, it is not clear how these two processes are linked to each other within the framework of subduction factory. Subduction zones are also central to plate tectonics, but their structures and how they have operated in the history of Earth still remain unresolved. This session aims to have a combined study from geophysics, geology and geochemistry for the purpose of better understanding the structures and processes of subduction zones. Therefore, we invite contributions from computational geodynamics and laboratory experiments as well as field-based investigations such as seismology, petrology and tectonics to address the above issues. |
