摘要
在分析成矿元素区域背景的基础上 ,依据岩、矿石的稀土配分型式、矿物包裹体的成分、成矿温度、盐度、压力等特征 ,探讨了湖南桥口铅锌矿成矿流体的物质来源和成矿流体的特征。认为成矿物质来源于震旦系地层和岩浆热液 ,流体中的水应是层间水、岩浆水和大气降水的混合流体 ,预示在矿区南部穹隆的深部存在隐伏岩体。
On the basis of the regional background of ore-forming elements; the rock and ore REE partition pattern; the components, ore-forming temperature,salinity and pressure of the mineral inclusions; the origin and characteristics of the ore-forming fluids are discussed.The results indicate that the ore-forming materials come from the sinian strata and thermal fluid of the magma, the water in the fluids is mixture of interstratified water,magmatic water and atomospheric water.It hints that there exist hidden rock body in the deep parts of the dome fold in the southern ore district.
