The Bangonghu- Nujiang suture zone is an important tectonic boundary, separating the Qiangtang and Lhasa blocks within the Tibetan Plateau (TP). This suture zone is one of the important geological windows for deciphering the growth history of TP. It can be divided into three parts: the western (from Banggong Lake to Gaze), middle (from Anduo to Dongqiao) and eastern (from Dingqing to Nujiang) sections. Few studies were undertaken in the eastern section. In this study, a vertical profile of granite near Guoqing Village of Basu County is considered for the fission track dating research, including zircon fission track (ZFT) and apatite fission track (AFT) with laser ablation inductively coupled plasma mass spectrometry (LA- ICPMS). The zircon U- Pb ages are centered at ~180 Ma, indicating that its crystallization age is the Early Jurassic. The ages of ZFT and AFT range at 180~130 Ma and 86~61 Ma, respectively. The Age- Elevation Relations (AER) of ZFT and AFT have a negative and positive slope, respectively. The QTQt simulation shows that the upper sample had experienced a fast- rate erosion during about 130~60 Ma, the middle had undergone a middle- rate erosion during 130~40 Ma, and the lower had maintained the slowest erosion since ~130 Ma. This differential uplift was caused by the earlier time of slab break- off in southward subduction than that in the northward subduction.
