在航、卫片解译的基础上,结合已有的区域地质填图成果,经过详细的野外观测研究,明确了甘孜-玉树断裂带最新地表活动形迹的空间展布特征。通过对断错地貌及新地层变形与位错的研究,结合(14)C和热释光(TL)测龄结果,对断裂带晚第四纪以来的平均滑动速率进行了初步研究。结果表明,甘孜-玉树断裂带的平均滑动速率为:甘孜段水平滑动速率为3.4±0.3mm/a,垂直滑动速率为2.2±0.1mm/a;马尼干戈段水平滑动速率为7±0.7mm/a;邓柯段为7.2±1.2mm/a;当江段为7.3±0.6mm/a。
On the basis of navigation and satellite interpretation, combined with the existing regional geological mapping results, through detailed field observation and study, the spatial distribution features of the latest surface activity traces of the Garze-Yushu fault zone have been clearly defined. Based on the study of the degenerated landform and the deformation and dislocation of the new formation, combined with the results of (14) C and TL measurements, the average slip rate of the fault zone since the late Quaternary has been studied. The results show that the average sliding rate of Ganzi-Yushu fault zone is: the horizontal sliding rate of Ganzi section is 3.4 ± 0.3mm / a and the vertical sliding rate is 2.2 ± 0.1mm / a; A rate of 7 ± 0.7mm / a; Deng Ke paragraph 7.2 ± 1.2mm / a; when the river is 7.3 ± 0.6mm / a.
