Geological characters of Baogutu porphyry copper deposit in Xinjiang, NW China

  • 新发现的包古图斑岩铜矿床位于准噶尔盆地西缘,达尔布特断裂以南的包古图地区。通过对V号主要赋矿岩体及钻孔岩心的野外和镜下观察,研究了矿体矿化情况、蚀变分带特征和矿石组合。对该矿床的流体包裹体分类研究表明,主成矿期成矿温度在180℃~450℃,包裹体的形成压力多在1~9MPa。由此得出的斑岩体的侵位深度在100~600m。黄铜矿和黄铁矿的δ^34S变化范围分别是-2.4‰~-0.8%o和-2.7‰~+0.7‰。对该矿床的初步研究认为,矿床是在埃达克质岩浆侵位到地壳浅部冷却成岩后,经历了两期含矿热液的作用而成矿的。早期形成Cu、Fe、Mo、Zn的硫化物矿物,可划分为4个成矿阶段;晚期形成Cu-Te-Bi-Au-Ag的复杂矿物组合。早期矿化形成的辉钼矿Re-0s年龄是310Ma。
