摘要
通过对由地下热(卤)水,埋藏水、变质水、深循环水等热液作用形成的一系列矿床的地质特征、控矿条件和硫、铅同位素特征分析,认为这一类矿床可归并为三个成矿系列,即雪峰-幕阜山加里东隆起区前泥盆系浅变质岩容矿的金、锑、汞、钨、砷、萤石、重晶石成矿系列;武陵加里东台坳区寒武—奥陶系矿源层容矿的铅、锌、汞、砷成矿系列;印支坳陷区上古生界碳酸盐岩容矿的铅、锌、铁、锰、金、锑、汞、硫成矿系列。
Systematical analysis of geological characteristics, ore-controlling factros and S-Pb isotopic components shows that deposits in Hunan Province formed by hydrothermal activity of brine,metamorphic solution and deep-circulating hot water can be divided into three metallogenetic series: Au-Sb-Hg-W-As-fluorite-barite series hosted in pre-Devonian slight-metamorphized rocks of Xuefengshan-Mufushan Caledonian upwarping region, the Pb-Zn-Hg-As series hosted in the Cambran-Ordovician source beds of Wuling Caledonian flatform and downwarping region, and the Pb-Zn-Fe-Mn-Au-Sb-Hg-S series hosted in late Palaeozoic carbonates of Indosinian downwarping region.
