| 摘 要： | 黔西北铅锌矿属后成层控矿床,赋矿地层中铅锌丰度和矿石铅同位素特征表明成矿金属来自下古生界。成矿受构造控制明显,矿床的形成和分布受垭都-蟒硐、威水和银牛复背斜构造的控制,复背斜带中的复杂构造段控制着矿田,而矿床受复杂构造段中的小背斜及其压性纵断层的上盘或陡翼的层间破碎带控制。

| Abstract: | The Pb-Zn ore deposit in northwestern Guizhou belongs to epigenetic strata-bound deposit type. The abundance of Pb.Zn in strata and Pb isotope feature of ore shows that metallogenic metals are derived from the Lower Palaeozoic. The formation and distribution of Pb-Zn ore deposits in northwestern Guizhou are controlled by the anticlinorium of Yadu-Mangdong, Weishui and Yingnu. Complicated structural sectors control the ore field in anticlinorium belt,while ore deposits are controlled by the small anticline in the complicated structural sectors and interlayer crushad zone between the upper wall and steep flank of the longitudinal compression fault. |
