Izu-Bonin-Mariana arc system:  synthesis and remaining questions

Session ID#: 81027

Session Description:
The Izu-Bonin-Mariana (IBM) system is arguably the best-studied example of an intra-oceanic arc. The region has been a primary focus of subduction factory studies for several decades. From 2014-2017, four International Ocean Discovery Program (IODP) cruises further explored this arc system, with drilling sites in the Izu forearc (subduction initiation), Izu reararc (arc evolution), west of the Kyushu-Palau remnant arc ridge (arc origins), and the Mariana forearc (serpentinite mud volcanoes). Proposals for future IODP drilling in the region are still being submitted. This session aims to highlight recent developments in IBM subduction zone studies resulting from these concentrated multi-disciplinary studies. We invite papers on subduction initiation, the formation and evolution of arc magmas and arc crust, volcanology and arc cyclicity, geochemical cycling, deep biosphere activity, geophysical structure, slab dynamics, mantle flow, and modeling studies. We also welcome papers on outstanding scientific questions that can be addressed in the IBM system.
