Abstract
Oman Drilling Project (ODP) aims at drilling fresh core samples that were constituents of the oceanic crust and mantle, with using Oman ophiolite. Scientific objectives of the ODP are to unravel oceanic crust formation at the mid-ocean ridge and interaction occurring within the oceanic crust-mantle at hydrosphere, the atmosphere and the biosphere. The ODP scientific studies are expected to launch next year. I will introduce its scientific impact and fascination, with showing several examples.
