Abstract

Abstract

The western Pacific is the most active area in tectonics and continental-ocean interaction in the globe. After more than 50 years of oceanic drilling in the western Pacific, many topics have been studied well, such as the origin of back-arc seafloor spreading, dynamic mechanism of the subduction factory, mantle evolution process, seismogenic zone, magmatism of hotspots, and paleo-sedimentary environments. However, tectonic histories of the western Pacific marginal basins are diverse and complex. We identified seven scientific issues yet to be fully analyzed, including unique oceanic lithospheric evolution of marginal basins, in-situ upper mantle serpentinization, mechanism of initial subduction and spreading, natures of submarine plateaus/seamounts/ridges/upwells/rises, intensity of hydrothermal circulation and its influence on the evolution of oceanic lithosphere, conjugate modes and mechanisms of lithospheric rifting and breakup, and oceanic red beds and abnormal sediments. We further recommended eight key drill targets, which are fluid geochemical profiling, seamount magma profiling, the Mussau trench and the Gagua ridge, the Ayu trough, the Caroline ridge system, the Eauripik rise, the Okinawa trough, and the Moho of marginal seas. Detailed geophysical investigations should be carried out on these targets before preparing drillable drilling proposals, and such efforts will help provide ideas for future ocean drilling research in the region.
