摘要

玉门断裂是祁连山北缘断裂带的组成部分 ,也属于酒西盆地南缘断裂带的一支 ,是酒西盆地内二级构造单元的边界。玉门断裂表现为强烈的逆冲推覆特征 ,并有不大的左行水平位移分量 ,次级断裂走滑方向与其走向有关 ;玉门断裂自早更新世以来一直活动 ,是现代地震断裂 ,也是玉门地震的发震断裂。
The Yumen fault, as a part of the northern Qilianshan fault zone, is a branch of the south-margin fault of the Jiuquan basin and also the boundary of the second-order structural element in this basin. The Yumen fault is characterized by intense thrusting and napping from south to north with relatively small sinistral displacement. The sense of the strike-slip of the secondary faults inside the Yumen fault is related to the trend of the faults. The Yumen fault has been active since the Early Pleistocene to the present day, so it is an active fault during the Holocene Epoch and a causative fault of the Yumen earthquake.
