集Co,Ni,As,Mn,Cu,Pb和Zn等元素,其中Co,As,Ni,Sb和Ge等元素主要是以类质同象的方式赋存于黄铁矿的晶格之中,大部分的Zn和Pb分别以闪锌矿微米级包裹体和方铅矿微/纳米级包裹体的形式赋存于黄铁矿中,而Cd,Mn和Cu,Ag则以类质同像的方式分别赋存于闪锌矿和方铅矿的晶格中.此外,黄铁矿的Co/Ni(均值1.0),Zn/Ni(均值42.0)和Cu/Ni(均值3.5)比值均指示其为热液型的黄铁矿.总体而言,大脑坡矿床黄铁矿微量元素特征可与典型MVT型铅锌矿床类比,在Co-Ni含量投影图上,样品点与MVT型矿床投影区高度吻合.结合矿床地质地球化学和黄铁矿微量元素特征,我们认为大脑坡矿床属于MVT型铅锌矿床.关键词:大脑坡铅锌矿床;黄铁矿;原位微量元素;MVT型矿床;LA-ICP-MS;......
