| 摘 要： | 黔西北铅锌成矿区海西期经历了北西向水城断陷的发育演化，沉积了巨厚的泥盆系、古炭系地层，形成区域内主要的矿化层位。青山－横塘矿区位于威水铅锌成矿带之水城中部矿田，区内构造发育，成矿条件有利，产出了青山、横塘等中小型矿床，从矿区内控矿断裂的同生活动特征分析，断陷盆地内ＮＷ 断裂的同生活动控制了矿带，活动较强烈地段控制了矿区，ＮＥ向断裂的同生活动控制了矿床。

| Abstract: | The lead-zinc mineral district at Hercynian in the northwest of Guizhou province has undergone the development and evolution of northwestern Shuicheng subsidence rift, sedimented Devonian and Carboniferous strata with a huge thickness during this period, and formed major mineralized strata in this district. Qingshan and Hengtang deposits are located in the middle Chuicheng ore field within Weining-Shuicheng ore belt in which structures well-developed and are suitable to form the lead-zinc deposits. Based on the analysis of contemporaneous activity of northe-west-trending faults within the subsidence basin, ore districts and the deposits are controlled by the contemporaneous activity of northwest-trending faults ,respectively, of the subsiednce basin.Morevoer, the deposits were reworked and destroyed by the activity of those structures formed in the orogeny period. Therefore,combination of the host-rock alteration and the contemporaneous activity of northeast-trending faults provides the prospecting indicators in the district. Meanwhile, it is worth to pay attention to the disorderly distrubutions of the petrology, petrological faces and the structures. |
