摘要
灯坪地区铜铅锌矿化特征表明:其成矿地质作用具有"热液充填交代"、"氧化淋积—次生富集"、"动力变质分异"的明显特征,且热液充填交代成矿作用是本区最为主要的成矿作用.矿物及包裹体特征、碳氧同位素组成及矿脉与地层岩体微量、稀土元素对比值的相关分析表明,热液充填交代成矿作用中成矿物质主要来源于地层,热液水主要来源于大气降水,部分来源于地层和岩浆残余水.
The copper-lead-zinc mineralization characteristics of DengPing area indicated the metallogenic geological process have obvious features about hydrothermal filling and re- placement, oxidation leaching area-secondary enrichment, and dynamic metamorphism dif- ferentiation. Heatliquid filling and replacement mineralization is the main mineralization in this area. The correlation analysis ratio of Mineral inclusions characteristics, carbon and ox- ygen isotopes and veins with the formation rock trace rare earth elements manifest that met- allogenic material of hydrothermal filling and replacement mineralization are mainly from the stratum. Hydrothermal water mainly comes from the atmosphere precipitation, partly from the stratigraphy and ma^ma residual water.
