| 摘 要： | 中牟凹陷边界断裂"左行走滑拉分"是中牟凹陷形成的主导因素,从中生代(侏罗纪)到早第三纪,沉积中心由北向南迁移,凹陷内的南部凹陷为南断北超的"箕"形凹陷,具有西深、东浅的特征,其演化主要分为三期:侏罗纪左行走滑拉分盆地发育期,早第三纪断陷期,晚第三纪、第四纪为坳陷期。

| Abstract: | The key factors for generation of the Zhongmu depression are marginal faults that are featured in ＂left lateral strikes slip pull＂ . From the Mesozoic era （Jurassic Period） to Paleogene, the center of sedimentation moved from the north to south. In the depression, the south part is featured in deep at west and shallow at east. In addition, the tectonic evolution of the Zhongrnu depression can be divided into 3 periods： ＂left lateral strikes slip pull＂ in Jurassic Period, faulted depression in Paleogene, and depression period in Neogene and Quaternary. |
