Scope This session aims to draw together cutting edge multi-disciplinary studies on oceanic and mature arcs to explore the current state of understanding and to project how efforts could be focused to augment our understanding of crust development. Topics covered will include geophysical explorations of subduction systems as well as the petrology, geology, and geochemistry of arc magmas and crust.
