【Abstract】 The Upper Permian Dibucuo Formation is newly established. It contains the Noeggerthiop-Pterophyllum mixed flora and has an unconformable contact with the underlying strata. Holocene volcanic rocks are found in the Gangdise magma arc and a group of isotopic dating data are obtained, which further enriches the temporal-spatial framework of the magmatic evolution in Gangdise.更多还原
