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 30 0 0m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 2 0— 4 .5Ma ,表明西域砾岩的沉积 (3.5— 1.6Ma)
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.
