Arc volcanism typically results in the formation of stratovolcanoes made up of crystal-rich calc-alkaline magmas, commonly linked to dehydration of the subducting slab followed by protracted differentiation through vertically extensive mush systems. However, subduction zones are intricately complex. They may, for example, involve monogenetic volcanism fed by more direct transfer pathways, as well as distinct eruptive activity in back-arc regions and beyond. A comprehensive understanding of magma generation, transport, and storage across and along arc settings, spanning oceanic to continental systems, is essential to better constrain the links between volcanic arcs, eruption style and hazards, and economic mineralization. This session invites contributions that delve into magma generation and transfer in subduction settings, exploring their relationships with magmatic architecture, eruption triggers, and mineralization potential. We encourage studies employing field observations, textural evidence, experimental petrology, and geochemical data from elements to isotopes, and from bulk rock to intra-crystal and melt heterogeneities. Additionally, we particularly welcome multi-disciplinary studies involving novel geochemical approaches and advanced computational techniques. We are excited to generate a diverse forum to discuss the intricacies of arc volcanoes across space and time. Join us in this collaborative effort to expand our knowledge of dynamic arc systems and their impact on our planet and society.
