The result shows that there are two Quaternary thrust (oblique) fault-fold belts, namely: the Miaoshan and Hongjianshan fault-fold belts, in the front area of the south wall’s strike-slip movement of the Tianjingshan fault zone. The Hejiakouzi Quaternary anticline, which is a part of the Miaoshan fault-fold belt, is mainly discussed. It is pointed out that the fold began to grow in the middle part near Hejiakouzi in the mid-late stage of middle Pleistocene epoch and then gradually developed towards the ends in late Quaternary. Based on the Cenozoic structural features, the genesis of the Miaoshan and Hongjianshan fault-fold belts and the kinematic relation they bear with the Tianjingshan fault zone are analyzed.展开更多
