    Abstract

    In this paper, Late Miocene blueschist and eclogite belts, including the world's youngest blueschist belt in Timor-Tanimbar Island chain, eastern Indonesia, and the world's youngest coesite-bearing eclogite, Papua New Guinea, together with selected Cenozoic high-pressure and ultrahigh-pressure metamorphic rocks are reviewed. From a synthesis of the geology, metamorphism and chronology of these rocks, the formation and exhumation process are evaluated and the significance on tectonics at convergent plate boundaries is discussed.
