摘要
梅仙铅锌银矿田形成于裂谷成矿环境,具有块状硫化物矿床特征,成矿物质和成矿热液有多来源特征,成矿经历了同生沉积、变质改造和岩浆热液叠加三个阶段,并与闽中裂谷带的构造演化密切相关,提出了"三阶段"成因模式。
Meixian Pb-Zn-Ag ore field were formed in the central Fujian rift zone, with the distinct characteristics of massive sulfide deposits. Both ore-forming materials and fluids were originated from multiple sources, and the mineral deposits were resulted from superimposition and transformation of multiple geological events. Consequently, a three-epoch genetic model, related to tectonic evolution of the rift, was proposed for Meixian Pb-Zn-Ag ore field.
