The strike of Huanghai block and Huaihai block in the east mainly tends towards north-east, while the strike of Shanxi block and the eastern edge of Ordos block in the west mainly tends towards north-west.(3) According to the feature of Moho, the crust of the research zone can be divided into six parts in the Shanxi block, Moho looks like a nearly north-south sunk belt, and the crust is thick; at the southern edge of the Inner Mongolia block and in the south of Yanshan block, Moho presents the structural features of fold belt, tending nearly towards east-west; at the eastern edge of Ordos block, the structure of Moho is relatively complex with nearly northwest folds.

3根据莫霍面的形态特征，研究区地壳可大致划分为6个区块；在山西地块范围内，莫霍面呈近南北向的凹陷带，地壳厚度大；内蒙古地块南缘和燕山地块南部，莫霍面表现出褶皱带的构造特征，其延展趋势为近东西方向；鄂尔多斯地块东缘，莫霍面构造相对复杂，呈近北西向凸、凹相伴的褶皱；黄淮海地块为莫霍面隆坳区，隆、坳相间排列，构造较复杂，但从整体上看，这是全区莫霍面最浅的隆起区段；鲁西台背斜主要为莫霍面断陷区，其断陷带沿枣庄－曲阜一线向北西方向延伸。
