[S-CG56] ICDP Oman Drilling Project: Oman to Oceanic Lithosphere to Island Arc Formation and Beyond

convener:Eiichi TAKAZAWA(Department of Geology, Faculty of Science, Niigata University), Katsuyoshi Michibayashi(Department of Earth and Planetary Sciences, Nagoya University), Sayantani Chatterjee(Niigata University, Department of Geology, Faculty of Science)

The on-going Oman Drilling Project has drilled numerous hard-rock cores of ancient oceanic lithosphere and the underlying subduction zone of the Samail ophiolite in Oman, with support from ICDP, IODP, the Sloan Foundation's Deep Carbon Observatory, and Japanese, US, and European research agencies. In this session, we invite presentations on the scientific results of Oman Drilling Project. We also invite related studies of on-land geological investigations of Oman ophiolites and experimental studies. The session is intended to be interdisciplinary, including the fields of geophysics, geochemistry, petrology, engineering, and biology.
