摘要
黔西北铅锌成矿区是川-滇-黔铅锌成矿域重要组成部分,也是贵州省主要的铅锌产地。研究认为,黔西北铅锌成矿区可划分为4个构造带,3个成矿亚带,铅锌矿产出受地层、岩性、构造、沉积环境等多重因素控制,岩性优于层位,断裂构造是主要控矿因素,构造具分级控矿特点。区内成矿地质条件优越,具备寻找大型、超大型矿床的潜力。作者结合区域地质特征,初步建立了地物化遥综合找矿模式。
The Pb-Zn metallogenic area in southwestern Guizhou Province is an important part of the Chuan-Dian-Qian Pb-Zn metallogenic district and it is also the main Pb-Zn producer in Guizhou Province. The authors have distinguished four structure belts and three metallogenie subbelts on the basis of the structural and mineralization features. The study showed that the controlling factors of Pb-Zn deposits include strategraphy, lithology, structure, sedimentation environment, etc. Lithology is more important than strategraphy, and fault structures are the most important controlling-ore factor. In the fault structures there is potential of seeking middle-scale or large-scale Pb-Zn deposits because the metallogenic geological conditions are much better there. The prospecting model for search of Pb- Zn deposits in the area has been established, which involves geology, chemistry , geophysics and remote sensing.
