摘要
由矿区在湘黔汞矿带所处的位置,结合区域地质及古地理背景,讨论了含矿围岩的成因。根据矿床地质及地球化学特征,论述了成矿作用的两个过程:成矿元素初步沉淀和后期再富集。并且认为含矿围岩的层间滑动是成矿元素后期活动再富集的有效机制。
In terms of the location of mining areas in Xiang-Qian mercury deposit belt as well as regional geology and paleogeographic setting.the genesis of country rocks is discussed. On the base of ore geology and geochemistry .two rpocesses are summarised of mineralization :ore forming elements primarily setting and re-enriching afterwards. The conclusion is reached that interforma-tional slip of country rocks is an effective mechanism for ore forming element activation and reenrichment.
