Scientific Objectives
Based on IODP Proposal 697-Full3, this expedition aims to understand crustal genesis and mantle evolution of the Izu-Bonin-Mariana (IBM) rear arc system by examining sediments and crust in the Philippine Sea. The primary objective is to obtain a temporal history of across-arc variation in magma composition during five main intervals of arc evolution.
Three main hypotheses will be tested: (1) geochemically asymmetric crust in the rear arch is either a fundamental trait or a secondary trait that develops during backarc spreading; (2) nonsteady state events, such as rifting, play a major role in the evolution of arc crust; and (3) the origin of the Izu rear arc seamount chains is related to mantle convection patterns.
