Abstract:

长江中下游地区是中国重要的铜、金、硫产地,区内分布着一系列喷流沉积及喷流沉积热液叠加改造型层状铜金矿床。本文以冬瓜山层状铜矿床为例,通过热液流体和矿石同位素地球化学研究,探讨层状铜矿床的成矿机制,重点分析了成矿物质的来源。冬瓜山铜矿床热液流体氢、氧、碳和锶同位素分析表明,成矿热液流体主要来自岩浆,混有少量大气降水;CO2可能主要来自被岩浆同化的原始地层中海相沉积碳酸盐;ISr具有地壳物质来源的特征。各种类型矿石的硫、铅同位素研究显示,硫具有海底喷流沉积和后期岩浆热液叠加作用的特征,铅则以上地壳铅为主,混有少量的地幔铅。上述同位素地球化学特征表明冬瓜山层状铜矿床是在原始沉积基础上,经燕山期岩浆热液叠加成矿作用所形成。
