摘　　要：川西凹陷近南北展布的合兴场构造带的发育史分为四个阶段:安县构造事件时期、中侏罗统千佛崖组时期(早燕山期)、古新世、第四纪,分别形成近EW向、近SN向、NNE向、NNW向四个方向的断裂带。其中古新世形成的NNE向断裂较多,为矿区的主期构造,后期形成的断裂对主期构造有一定的破坏或改造,因此矿区构造形态是四期构造相互叠加演化的结果。The Western Sichuan depression HEXINGCHANG Sn trending tectonic belt development history is divided into four stages： Anxian tectonic event period, Middle Jurassic Qianfoya period（early Yanshan period）, quaternary Paleocene, respectively, formed near EW, near SN, NNE, NNW to four directions the fault zone. The Paleocene formation of NNE faults are the main stage for the tectonic fracture, formed in the late stage of destruction or modification of some of the main structure, the tectonic form is four tectonic superimposition of the evolution results.
