本文主要介绍用正演法验证川东北亭子铺地区地震时间剖面上出现的深层隆起与浅层向斜的反扣现象。正演结果表明,时间剖面上的深层隆起显示是圈闭的背斜构造的反映。

A forward solution to verify the phenomenon of appearing of shallow sycline over deep upheaval in seismic time section is mainly presented in this paper. It has been proved that the indication of the upheaval at the lower part of the section is the reflection of trapped anticline.
