摘要
Based on analysis on fission track dating of apatite and zircon in the granite and sand samples collected from the south, middle and north segment of Longmen Mountains, it is found that the uplift process of Longmen Mountains can be divided into different segments along strike direction and zones in East-West direction. From Songpan-Ganzi fold belt through Longmen thrust belt to western Sichuan foreland basin, the entire Songpan-Ganzi fold belt has experienced regional uplift,and the fission track age shows positive correlation with altitude. While in Longmen thrust belt, the fission track age has negative or no correlation with altitude, suggesting that thrust fault play a dominant role during the uplift process.
