然后分析区域构造特征和展布格局，特别强调逆冲推覆断裂的重要性；

Then, the regional structure characteristics and distribution pattern are analyzed and the importance of thrust nappe fault is emphasized especially.

喜山期持续的区域应力作用使那里沟背斜SE翼沿软弱面断裂，经递进扩展变形，最终形成逆冲推覆构造。

The SE limb of Naligou anticline was fractured in the action of persistent regional stressing and expanded into detachment-thrust structure during Himalayan orogenic period.

推覆构造体系是由几条逆冲断裂带及其逆冲席、逆冲片组成，主干断层与次级断层组成叠瓦式构造。

The structural system of nappe consists of several overthrust fracture belts, thrust sheets and thrust slices, and master fault and secondary fault form an imbricate structure.
