【摘要】 琵琶山铅锌铜多金属矿体产于白垩系红色砂砾岩和板溪群板岩的不整合接触带中,不整合面总体走向NE30°,矿体沿不整合面在有利成矿部位呈豆荚状分布.按照成矿时间可划分为早期硅化阶段、中期硫化物成矿阶段、后期改造阶段.根据矿床地质特征和矿体的空间展布规律,认为沿不整合面深部及其北东方向找矿前景看好.更多还原

【Abstract】 Piper Mountain’s Pt-Zn-Cu polymetal orebodies are produced in the contact zone of the Cretaceous red glutenite and Banxi Group slate. These orebodies,forming ore pods,are distributed favorably along the NE30°-oriented unconformity.The formation of the ore deposit,according to the time period,has experienced three stages—the early silicification,the mineralization of sulphide,and the late deformation. Considering geological charateristics of this ore deposit and the spatial distribution law of orebodies,the unconformity’s deep area as well as its northeast are prospective targets for ore-finding.更多还原
