主要遵循4个基本步骤，轴面分析是基础，断层褶皱形态分析是核心，平衡观念是灵魂，构造复原是手段。

The structural model should be built in 4 steps with the axial surface analysis as the basis, the fault-fold geometric analysis as the key, the balanced idea as the guidance and the stru.

构造裂缝的形成和分布与局部构造作用(断层、褶皱作用)有关。

The forming and distribution of the structural fractures are related to the local tectonics (e. g. the rifting and the folding).
