| Research Abstract |
This research aims to establish the international leadership of Japanese scientists for four IODP (Integrated Ocean Drilling Program)-related research projects and to realize drilling experiments for these projects by ‘Chikyu.’ NanTroSEIZE conducted Chikyu drilling at Nankai Trough and has decoded the stress and thermal structure of the subduction zone complex including the seismogenic zone. IBM proposed the continental crust formation model based on subarc crust-mantle structure and petrological/geological constraints, which enables four drilling experiments to be on a schedule of IODP expeditions. LIP/OAE found a close linkage between surface global changes and Os-Pb isotopic record decoded in marine sediments. Mohole conducted geophysical and geological surveys both in the ocean and the obducted oceanic crust section and, based on these data, decided successfully three candidates for mantle-drilling.
