随着晚三叠世龙门山造山带的崛起,四川前陆盆地开始形成。强烈的喜马拉雅运动使龙门山进一步崛起,造就了龙门山与四川前陆盆地的盆-山耦合景观。结合遥感解译与实地调查,发现江油-灌县断裂带控制着前陆盆地的边缘,是一个构造形迹较为复杂的盆-山耦合断裂,由二王庙断裂和香水断裂组成,其主体断裂为二王庙断裂。而在四川前陆盆地西缘的香水断裂是半隐伏乃至全隐伏的盆地基底断裂构造,断裂在江油南西裸露地表且控制盆地边界,但在江油北东到广元则处于隐伏状态。香水断裂对盆地边缘早-中侏罗世盆地沉积相和晚侏罗世-早白垩世所谓＂城墙岩系＂巨厚磨拉石建造的形成均具有较强的控制性。

With the rise of Longmen Mountain in the Late Triassic,Sichuan foreland basin began to form.Strong movement of the Himalayas forced Longmen Mountain to further rise,created a basin-mountain coupling landscape between the foreland basin of Sichuan and Longmen Mountain.In this paper,integrating remote sensing interpretation and field survey,found that Jiangyou-Guanxian fault zone controlled the edge of the foreland basin which was a complex construct features basin-mountain coupling fracture,it consisted of two king temple fault and Xiangshui fault,its main fault was the two king temple fault.The Xiangshui fault in the western margin of Sichuan foreland basin was a semi-concealed even concealed basement fault,the fault was bare upon surface in the southwest of Jiangyou and controlled the basin boundary,but in a concealed state from the northeast of Jiangyou to the Guangyuan.Xiangshui fault had strong controlling to the early-middle Jurassic sedimentary facies and the formation of Late Jurassic-Early Cretaceous’ thick molasse construction which called "wall rock series".
