Abstract: 通过分析高精度数字化SPOT卫星影像,结合野外考察和年代学测试,对阿尔金南缘走滑断裂带的3个典型走滑断层断错地貌点进行了研究.在安南坝沟,阿尔金南缘走滑断裂带一主要分支自(9.36±0.73)ka BP以来的左旋滑动速率为(7 5±1.7)mm/a;在七个泉子阿尔金南缘走滑断裂带有4条分支,其中1条规模较小的断层分支自(13.86±1.07)ka BP以来的左旋滑动速率为(2.3±0.5)mm/a,由此推断七个泉子附近断裂带全新世以来的滑动速率为(6.9±1.5)~(9.2±2.0)mm/a;约马克其断裂带自(4.73±0.38)ka BP以来的左旋滑动速率为(10.6±3.0)mm/a.综合以上各点结果,阿尔金南缘走滑断裂带中段88°30′E与93°05′E之间全新世以来的水平滑动速率为7~11mm/a,与最新的GPS观测结果非常接近.
