摘要
In this paper, the authors study the geological features and its evolutionary history and late reformation of the Lower Cretaceous in the south of Ordos Basin. Detailed field investigation, stratum distribution, sedimentary characteristics analysis and the erosion thickness restoration are adopted. The Lower Cretaceous stratum in the south of Ordos Basin has experienced two sedimentary cycle periods of Yijun Luohe-Huanhe Huachi and Luohandong-Jingchuan, which shows the form of east slow and west steeper, as an asymmetric syncline. The erosion thickness restoration indicates that the most erosion thickness may reach to 2 000 meters at the eastern and southern side.
