| 摘 要： | 在上扬子地台及其周缘分布着众多铅锌矿，这些位于震旦系一奥陶系海相碳酸盐岩中受岩性控制且受断裂控矿明显，以层状、似层状为主，成矿温度相差较大，成矿流体盐度高，成矿流体为热卤水的沉积岩型铅锌矿床，有着特殊的成矿背景及成矿条件，与MVT相似也有不同特征的铅锌矿称为“扬子型”铅锌矿。新一轮国土资源大调查以来，该地区扬子型铅锌矿找矿及勘查取得重要进展，在近几年的找矿工作中已累计探明铅锌资源量1000万吨以上。通过深入研究，总结出具有中国特色的“扬子型”铅锌矿的成矿规律及找矿标志。

| Abstract: | Lead-zinc deposits were widespread in upper Yangtze plate and periphery area. All these deposits, which distributed in Sinian-Qrdovician marine carbonate rocks, controlled by lithology and fault system, main- ly have stratiform and stratoid structure, variable metallogenic temperature, mineralized fluid are hydrothermal brine with high salinity,have special metallogenic setting and ore-forming conditions, have a similar and differ- ent characteristics with MVT lead-zinc deposit. The sedimentary-hosted lead-zinc epigenetic deposits with above characters are defined as Yangtze type lead-zinc deposits. Since the whole country survey in land and resource, significant progress has been made in Yangtze type lead-zinc deposits exploration in recent years. The prospecting work has accumulated proven lead and zinc resources of 10 million tons. To summarize the metallogenic regularity and prospecting criteria of Yangtze type lead-zinc deposits has great signification for further research. |
