A number of IODP expeditions have focused on hard-rock drilling over the last decade including Expedition 352 in 2014, which drilled the volcanic sequence associated with subduction initiation in the Bonin fore-arc, and Expedition 360, which drilled the lithosphere associated with ultraslow-spreading at the Southwest Indian Ridge in 2016. 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. Preliminary results from the recent Expeditions are also welcome. The session also seeks to explore the crust-mantle connections among ophiolites, at divergent and convergent plate boundaries and ocean island settings. Crustal thickness and composition are correlated on ocean islands where the spatial variability in erupted magma compositions is reflected in the composition of the crust. To what extend to crustal composition reflect those of the primary melts? How diverse is the spectrum of primary melts and which factors may contribute to its variations? What is the influence of crustal processing vs. primary magma diversity in creating the diversity of the Earth's crust? 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.
