Dear Colleagues,
We would like to bring to your attention Session #2384 "Drilling the Izu-Bonin-Mariana System: First Results and Related Studies" at the 2014 Fall AGU meeting on 15-19 December.
Three IODP expeditions will investigate the northern Izu-Bonin-Mariana (IBM) subduction system during 2014. Expedition 350 aims to drill sediment and rear-arc crust west of the Izu arc volcanic front to understand arc crust differentiation, mantle evolution during arc rifting, and patterns of arc and rear-arc volcanism since Paleogene. Expedition 351 will target sediment and oceanic crust west of the northern Kyushu-Palau ridge to investigate the nature of the crust that predated IBM subduction, the mechanism of subduction initiation, and Paleogene arc evolution. Expedition 352 will target the volcanic sequence in the fore-arc east of the Bonin Islands to investigate subduction initiation and chemical gradients in subducted fluids and mantle melting during early crust production. This leg also will test the hypothesis that supra-subduction zone ophiolites are created in fore-arcs. The first results from all three expeditions will be presented. Presentations on related research also are welcome.
Please consider submitting an abstract to our session. The deadline for abstract submission is 6 August. Abstract submission details are available at http://fallmeeting.agu.org/2014/scientific-program/

Mark Reagan (University of Iowa)
