The well mineralized area of Nage Pb - Zn - polymetallic Sulfide Ore Deposit in Congjiang is the place between near east - west Weidongxi fault（F₂） and middle - upper part of Jialu Formation of Xiajiang group(Qbj^2a). Ore output is strictly controUed by structures,and the fault is the first ore - controlling factor.And the Zaibian fault （F₁） is for leading the ore structure,Weidongxi fault（F₂ ） and the subprime fault are for ore control and let mine structure,its fault belt in rock deformation points with phenomenon is obvious,structure and mineralizing has close relationship.Obviously,from a series of symbolized rock deformation of fabrics,it is found that the fault as a F₂ strike-slip characteristic of the fault is obvious,strike - slip direction is to the left.In this paper,Nage Pb - Zn - polymetallic Sulfide Ore Deposit ore - controlling structures in deformed rocks of the macro and micro deformation is analyzed,the ductile deformation features are obvious,brittle deformation characteristics also has relative development.Deformation mechanism has a brittle deformation characteristics of toughness conversion,and it is deformed in the low temperature, low strain rate,high stress difference under the environment of the deformation.The study area is mainly for multi -stage belt - type brittle - ductile shear zone,in accordance with the first extrusion and shear,and then with the extensional process.
