摘　　要：汝阳王坪西沟大型铅锌银矿床，属构造蚀变岩型热液矿床，主要工业矿体呈似层状或大透镜状赋存于断裂破碎带中。矿床产状与矿带一致，属陡斜倾矿体，在走向或倾向上呈舒缓波状，膨缩特征明显。铅含量大于锌，银以类质同象赋存于方铅矿品格中，铅与银呈正比变化。诚然，在能圈出富矿体的铅锌矿体部位，也是银矿体的分布空间；矿石组构方面，硫化矿石结构主要有半自形-它形粒状结构为主；构造则以细脉浸染状构造和脉状块状构造为主。Large sized Wangpingxigou lead and zinc silver deposit of Ruyang belongs to the tectonic altered rock type of hydrotherrnal deposit. Major industrial ore bodies show layer or lenticular occurrence in fault fracture zone. Occurrence of ore deposits and ore belt is consistent, belongs to the steep inclined dip orebody. It is on to or tends to slow wave~ the characteristic of bulk shrinkage is obvious. Lead content is greater than the zinc, silver with such quality as occurrence in galena character, lead and silver were in positively relation. It is true, where can circle the lead-zinc mine rich ore body, also existed the silver ore bodies; On ore fabric, structure of sulfide ores are mainly hypidiomorphic, and the structure with fine vein disseminated and vein block structure are dominant.
