| 摘 要： | 运用磷灰石裂变径迹高差法对普鲁地区克里雅河南岸海拔3000m花岗岩山体进行了分析，显示西昆仑北部山前在晚新生代9－8Ma左右发育有抬升事件，区内西域砾岩中花岗岩砾石的磷灰石裂变径迹年龄跨度至少20－4．5Ma，表明西域砾岩的沉积（3．5－1．6Ma）并非对应西昆仑的快速抬升。

| Abstract: | Apatite fission track dating data of 9 samples selected from Pulu range in the northern regions of west Kunlun mountain were obtained. The results recorded that rapid uplift occurred in 8-9Ma B.P. in this region. The FT ages range from 20Ma to 4.5Ma, so we infer that the deposited age (3.5-1.6Ma) of Xiyu conglomerate is uncertainly corresponding to the time of rapid uplift of west Kunlun moutain. |
