摘要
产于元古宙碳酸盐岩中的浑江市铅锌矿，多年来被认为是层控沉积矿床。作者通过详细的室内外构造解析工作，认为该矿区及其区域上相当大的范围内为韧性剪切带发育地带，尽管铅锌矿床在区域上与碳酸盐岩有较密切的依赖关系，但具有开采价值矿体的生成与赋存主要受韧性剪切活动所制约，因而提出新的成矿、找矿模式。
On the basis of structural and petrological studies of the region, it is believed that the Huang goushan mining area has undergone a strong ductile deformation, which is commonly inhomogeneous and localized in zones of varying sizes. The dluctile nature is obvious and characterized by the development of s (the mylonitic foliation)─C (shear plane) structures,stretching lineations,ubiquitous mylonitization of rocks and the scaly structure belts.The formation and distribution of the Pb─Zn deposits of the studied area are mainly controlled by the ductile shear zone. The scaly structure belts control the distribution of mineralized zones. Foliation of s and c control the distribution of ore dodies of economic value. The incontinuity and equidistance of the scaly structure belts led to the formation of orebodies and its present distribution.Through research on the characteristics of ductile shear zone and their controll effects on Pb─Zn orebodies the mining area and its deeper part ,and three other belts of the studied region are suggested as favourable areas for prospecting.
