摘要:
依据最新地震、地质资料研究，黄骅坳陷歧口凹陷构造演化主要分为：歧口凹陷裂陷阶段和歧口凹陷裂后阶段，裂陷阶段又可分为裂陷I幕(沙河街三段–沙河街二段)与裂陷II幕(沙河街组一段–东营组)，歧口凹陷裂后阶段又可分为稳定热沉降幕(馆陶组)与加速沉降幕(明化镇组–第四系)。
Using the newest seismic and geological datum, the Qikou sag of the Huanghua depression’s tectonic evolution can be divided into chasmic stage and after chasmic stage. Chasmic stage can be divided into chasmic I act (the third group of Shahejie group-the second group of Shahejie group) and chasmic II act (the first group of Shahejie group-the Dongying group). The after chasmic stage can be divided into the stability hot act (The Guantao group) and the speed up act (The Minghuazhen group-the quaternary).
