Abstract

From the results of fission-track dating of different minerals from the granodiorite of the middle Gangdise granitoids belt in Qinghai-Xizang Plateau,the authors suggest that the uplifting of southern Qinghai-Xizang Plateau is episodic,there having occurred a slow uplifting from the emplacement of the intrusive to about 30 Ma,which was followed by an acceleration in velocity from 30 to 7 Ma and a rapid uplifting since 7 Ma.
