摘　　要：开平凹陷非典型的凹陷结构以及凹陷中部KP11地质异常体的成因近年来引发了较大争议。本文在阐述开平主洼的拆离作用及其证据的基础上,分析了KP11地质异常体的成因,搭建了开平地区南北向构造格架,恢复了开平凹陷的构造演化过程,并对裂陷期文昌组的两幕伸展作用对沉积的控制进行简要分析。The atypical structure of Kaiping Depression and the forming mechanism of KP11 anomalous body have aroused great arguments in recent years. On the basis of analyzing the detachment effect and its evidence,this article elaborates the forming mechanism of KP11 anomalous body,sets up the structural framework of Kaiping Depression,restores its structural evolution process,and briefly states the control effect of two-stage extension on sedimentation of Wenchang Fm..
