摘要
湘黔铅锌矿带主要受下寒武统清虚洞组的碳酸盐台地边缘浅滩—藻礁相控制,矿床位于热液活动活跃的湘黔深断裂带边缘。矿体受岩石的原生孔隙和容矿层内构造等多因素控制。区内分布众多铅锌或汞锌地球化学异常带,与清虚洞组地层分布及其矿床集中区相吻合。本文针对湘黔铅锌矿带下寒武统清虚洞组地层中铅锌矿富矿成矿规律进行总结,可为进一步找矿提供借鉴。
The Hunan-Guizhou Pb-Zn metallogenic belt is mainly controlled by Shoals and algal reef phase located in the edge of Carbonate platform in Lower Cambrian Qingxudong formation.The deposits are located at the edge of Hunan-Guizhou deep fault where hydrothermal solution is active.The ore bodies are mainly controlled by multi-factors,including primary porosity of rocks and structures in ore-bearing strata.In the study area,numerous Pb-Zn or mercury-zinc geochemical anomaly zones are agree well with strata distribution of Qingxudong formation and its deposits concentration area.The formation rules of high-grade Pb-Zn ore in Lower Cambrian Qingxudong formation is summarized in this paper,which can provide reference for further prospection.
