The cleavage and schistosity acted as an axial plane role in the early generation of compressed shearfold, and changed into a slip plane in the later generation of flexural slip fold.
片理(劈理)为早世代挤压-剪切褶皱的轴面片理,又成为晚世代弯滑褶皱的滑动面;

The ore belts, mining area, deposits and ore-bodies are all controlled by the deep faults, large scale shear zones and the fold and fault-crack system aside.
深断裂带、大型剪切带及其旁侧的褶皱及断裂裂隙系统控制矿带、矿区、矿床和矿体。

The equilibrium equation of surrounding rock mining fault system is established. The fault destablizing process with shear failure pattern belongs to fold catastrophe model.
