Research Abstract

Purpose of this study is to realize P-T-t conditions from the multiple collision zones in SE Asia. Very high-T and -P conditions were obtained from the collision zone between the Indochina and South China cratons, which indicate that deep continental subduction had occurred in this collision zone. The age mostly yielded the Late Permian. On the other hand, no evidences of the subduction were obtained from the Sibumas-Indochina collision zone, and their ages are little younger than that of the Indochina-South China collision. These characteristics strongly imply that there are significant age gap and different collision system in multiple collision zones in SE Asia during the Pangaea formation.
