[S-IT05] Hard-Rock Drilling: Oceanic Lithosphere to Island Arc Formation and Beyond

Wed. May 27, 2015 11:00 AM - 12:45 PM 303 (3F)

A limited number of IODP expeditions have been conducted for hard-rock drilling for the last decade including most recent expeditions investigating the northern Izu-Bonin-Mariana (IBM) subduction system during 2014 (Expeditions 350, 351 and 352). In this session, we review the current status of our understanding for oceanic lithosphere and island arc formation or anything important beyond and discuss significant issue to be answered by up-coming/future hard-rock drilling. The session invites contributions from interdisciplinary field ranging from geophysics, geochemistry, petrology, engineering and biology working on hard-rock cores/samples from the expeditions or any other research vessels as well as on-land geology such as ophiolites. Preliminary results from the three IBM Expeditions are also welcome.
