The Oman Drilling Project (OmanDP; 2016-2018) has recovered 3200 m of diamond drillcore that sample three intervals within the gabbroic lower crust, the crust-mantle transition, partially serpentinised peridotite undergoing active alteration, and the transition from the mantle into the underlying metamorphic sole of the Samail ophiolite in Oman, arguably the best-preserved ophiolite. Most of the boreholes have been geophysically logged and the cores have undergone extensive IODP standard core description onboard the DV Chikyu, supplemented with X-ray CT and high resolution infrared scanning of the entire core. These cores and boreholes can be used to investigate the full spectrum of processes operating during the formation and modification of oceanic crust and shallow mantle. These processes involve mass and energy transfer between all the major components of the Earth system (the mantle, the crust, the hydrosphere, the atmosphere and the biosphere) and occur over a broad range of temperatures, depths and tectonic settings. In this session, we invite abstracts relating to the Oman Drilling Project including core analysis, geophysical logging and microbial studies as well as studies related to the Samail ophiolite and the oceanic lithosphere in general.
