Based on the macroscopic characteristics, microstructure and fabric of the tectonite in the Yingxin fault zone,this paper proves that there are two types of tectonite, i.

依据龙门山中段映秀断裂带构的宏观地质特征、显微构及组构特征，论证了构有性和韧性两大类型，形成序次上为先韧性后性。

In the ductile shear belt,the alteration and zonation of tectonite and wall rock are obviously,and miliolite belt,quartz,iron pyrite,ankerite alteration belt and gold mineralization belt are trinity.

韧性剪切带内构、围蚀变分带明显,并有典型的“(超)糜棱—石英、黄铁矿、铁白云石化—金矿化”等“三位一体”成矿特征。
