中文摘要:文章从碳、氢、氧、硫、铅、锶等同位素地球化学方面探讨了湘中锑金矿床的成矿物质与成矿流体来源。研究表明:湘中盆地中锑矿床的碳、硫等矿化剂主要来源于基底地层,而盆地边缘锑(金)矿床的碳、硫等矿化剂来源于深部岩浆作用;Au,Sb等成矿物质都来源于基底碎屑岩;成矿流体主要为大气降水。
Abstract:Central Hunan area is a world_famous area for Sb (Au) mineralization. This paper has systematically studied carbon, hydrogen, oxygen, sulfur, lead and strontium isotopic geochemical characteristics of Sb (Au) deposits in central Hunan and discussed sources of ore_forming metals and ore_forming fluids. The researches show that the ore_forming metals such as Sb and Au came from basement clastics, while the ore_forming fluids were mainly derived from meteoric water.
