摘要
闪锌矿、方铅矿、黄铁矿、石英及重晶石是镇旬铅锌矿田的主要矿物。不同世代的闪锌矿 ,其形态、颜色及矿物共生组合的差异 ,反映了形成条件的差异。主要矿物的化学成份、微量元素含量 ,反映了本区铅锌矿床与西成 -凤太地区的喷流沉积改造型铅锌矿床一样 ,即与国内岩浆热液型铅锌矿床有相似之处 ,更与典型的沉积改造型铅锌矿床类同。
The principal minerals of lead-zinc deposit in Zhenxun are shalerite,galena,pyrite,quartz and barite.The shape,color and coexisting minerals of shalerite are different because of different time,which reflect the differences of formation conditions.The chemical components and micro-elements content of principal minerals might be concluded that this lead-zinc deposit is the same as one to be formed by eruption sedimentary in Xicheng-Fengtai area,that is similar to this lead-zinc one of magmatic hydrothermal in China .
