本文依据斑岩铜矿中黄铁矿硫同位素组成研究,并与其它铜矿类型对比,初步探讨其成矿物质来源。根据硫同位素组成特征,划为三种类型:地幔原生岩浆岩源型,如基性和超基性岩铜镍矿床,与蛇绿岩套有关铜矿床等,其硫同位素比值特征与陨石值类似,表明未受到污染;地壳混合岩浆岩源型,如中基性、中酸性岩浆岩有关斑岩铜矿,以及与火山岩有关铜矿,硫同位素受到污
Based on the study of the sulfur isotopic compositions of pyrite in porphyry copper deposits and the comparison with other copper types, the source of ore-forming materials is discussed. According to the characteristics of sulfur isotopes, they are divided into three types: mantle primary magmatic source types, such as basic and ultrabasic rock-copper nickel deposits and ophiolite sets related copper deposits. The sulfur isotopic ratios and meteorite values Similarly, it shows that it has not been polluted. Crustal mixed magmatic source types, such as porphyry copper deposits of medium and medium acid magmatic rocks, and copper deposits associated with volcanic rocks, the sulfur isotopes are contaminated
