摘要
使用全站仪实测了天山南麓北轮台逆断裂库尔楚段阿克艾肯—喀腊萨喀腊阿塔木冲洪积扇断层崖地形地貌 ,采用 10 Be测年方法测定了该冲洪积扇的形成年龄 ,得到该断裂段垂直位移滑动速率为 0 .4 8mm /a、0 .85～ 1.0 mm/a和 1.5 2 mm/a。
Beiluntai fault zone is the boundary line between Tarim basin and south Tianshan Mts. Akeaiken-Kalasakalaatamu alluvial and diluvial fan is lied in Kuerchu segment of Beiluntai fault in the south edge of Tianshan.The topographic and geomorphic survey of the fan was made using Total Station,and the age of the fan was measured through 10Be dating.The vertical slip rate of the segment is calculated to be 0.48 mm/a,0.85-1.0 mm/a and 1.52 mm/a,and the horizontal shortening rate of the segment and the horizontal shortening amount of Tianshan since Quaternary were calculated,too.
