通南巴构造位于米仓山构造带和大巴山弧形构造带的交接处，向南与川中低缓构造带以通江凹陷相接。其现今主要存在北东向和北西向两组构造体系，它们的形成完全受区域构造的控制，在成因上两者是相辅相成的，该地区的现今构造形迹是多期构造运动的结果。文中研究了通南巴地区主要的构造特征，并且对主要构造形成的成因进行了探讨，总结出了3种成因模式。

Tongnanba structure is situated in the connection part of Micang mountain structure belt and Daba mountain structure belt. The
structure is linked together with the gentle structure belt in central Sichuan by Tongjiang Depression. Now there are two structure
systems with NE and NW strikes, which are controlled fully by the regional tectonic and are supplement each other on the origins.
The present vestages of Tongnanba structure are the result of multiphase structure movements. This paper studies the major
structural features and origins in Tongnanba region, and summarizes the three genetic models.
