On the section, the imbricatethrust zone is situated below the front margin of the triangular-zone structure, and they are overlapping distributed on plane.
在剖面上，叠瓦冲断带位于三角带构造的前缘下方，平面上呈重叠分布。

The middle(early Himalayan)is the main deformation, characterized by the imbricatethrust structure system, whose west zone shows thrusting from SW toward NE.
中期（喜马拉雅早期）是主变形期，西带显示由SW向NE逆冲，以叠瓦状逆冲构造系统为其特征。

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.
