摘要
位于库车县北面的却勒塔格活动断裂带发育在上第三系塑性岩层中 ,为逆断层或逆掩断层。其部分地段在晚更新世晚期以后断层性质转化为正断层 ,并错动渭干河阶地。断层滑动速率在1 mm/ a以内。却勒塔格活动断裂带为表层滑脱构造。
Queletage active fault zone is located in the north of Kuche County,Xinjiang,and develops in the plastic beds of Tertiary.Generally,it has the property of thrust or overthrust,but after late Late Pleistocene,it changed into normal fault on some segments, and faulted the terrace of the Weigan river. The slip rate of the faults is less than 1 mm/a. Queletage fault zone is a surface decollement structure.
