The tectonites are characterized by macroscopic cataclastic and microscopic mylonitic structures.
宏观碎裂结构与微观糜棱状结构是断层构造岩的主要特点。

The low reservoir permeability is mainly caused by destroyed fracture system, producing and increasing fragmented coal and mylonitic coal.
碎粒煤和糜棱煤的不断产生与增加及对裂隙系统的严重破坏是煤储层低渗透性主要影响因素；

Especially, tectonic breccia associated with mylonitic lithofacies in tenacity shear zone, it has significance in dividing different shear zones on regional scale.
