摘　　要：昆仑山中段策勒西南冲洪积扇上的古地震形变带总体走向北东 ,长约 4 0 km,最宽有 6 km。该形变带由 50多条长短不一的正反断层陡坎组成 ,陡坎最长有 13km,最高有 2 0 m,为多次古地震造成的结果。古地震最高震级估计在On the alluvial and diluvial fan in the middle part of Kunlun Mountain, namely,the southwest of Cele, Xinjiang, there is an above 40 km long, 3 to 6 km wide, 70° general strike paleoearthquake deformation belt. The belt consists of over 50 normal and reverse fault scarps with varying lengths; the longest scarp is 13 km, and the highest is 20 m, the result of many times of paleoearthquakes. It is estimated that the strongest paleoearthquake is with the magnitude of M>7.
