贵州从江友能铅锌矿是断控型中低温热液矿床，发育北西向和近南北向2组断裂，北西向压扭性党扭断层是控矿断裂，是主要控矿构造。矿体呈囊状、透镜状主要赋存于甲路组、乌叶组地层中。本文从矿石特征及控矿断裂特征2方面讨论成矿特征。矿体严格受断裂控制，该矿床分为4个成矿阶段，第Ⅱ，Ⅲ阶段为主要成矿阶段；研究发现断层泥厚度－矿体厚度－品位三者之间存在一种正相关关系，矿体具有膨大狭缩特征。

The Youneng lead zinc mine controlled by fracture in the town of Congjiang belongs to low -middle temperature hydrothermal deposit,which develops the NW and SN two groups’fractures.The NW pressure -shear Dangniu layer is the ore control fault,which is the main ore controlling structure.Cystic and lenticular orebody mainly occurs in Jialu Formation and Wuye Formation.This paper discusses the characteristics of mineralization from the two aspects,i.e.the ore characteristics and the ore fracture characteristics.The orebody is strictly controlled by faults.Mineralization of the deposit is divided into four phases,among which theⅡ stage and the Ⅲ stage are the main mineralization stages.The study finds that there is a positive correlation between the gouge thickness,the orebody thickness,and the ore grade.Orebody has swollen pinched features.
