Research Abstract

Field survey and chemical analysis were carried out for the Oman ophiolite, a large fragment of 100 million year-old oceanic lithosphere. The field survey revealed widespread occurrence of boninite which represents the volcanic rock formed in subduction zone with extremely hot thermal structure. The chemical analysis showed that hydrous fluids liberated from subducted, amphibolite-facies oceanic crust (500~700℃) were widely incorporated in magma genesis in the initial stage of subduction.
