在四川盆地东北部,由于地质力学环境复杂且不稳定,形成了较为特殊的构造形迹组合,特别是在平面上其构造形迹变化更加特殊,形成了各种形式的构造式样,这不是一次构造运动的结果,而是多期构造运动共同作用的结果。通过对该区横向构造式样和剖面构造式样的分析,总结了该区构造式样的基本特征和形成发育规律,指出了该区未来天然气勘探的主要方向。

Because the geomechanical environment in the northeastern area of Sichuan basin is complicated and unstable, the combination of structural features formed thereis specific, and exceptionally the planar change of structural features is much more specific. All kinds of structural styles formed there is not formed in onestage of movement but in many stages of movements. This paper summarizes the basic features and the formation and development rule of the structural styles instudy area on the basis of analyzing the transverse structural styles and the sectional structural styles.
