| Abstract |
The objectives for Expedition 352 were to drill through the entire volcanic sequence of the Bonin fore arc to
- Obtain a high-fidelity record of magmatic evolution during subduction initiation and early arc development,
- Test the hypothesis that fore-arc basalt lies beneath boninite and understand chemical gradients within these units and across the transition,
- Use drilling results to understand how mantle melting processes evolve during and after subduction initiation, and
- Test the hypothesis that the fore-arc lithosphere created during subduction initiation is the birthplace of suprasubduction zone (SSZ) ophiolites.
