| 摘 要： | 很多矿产都产于不整合面及其附近，常见的有油气、金、铀、铅锌、铜、锑与铂族元素等，不整合面与成矿的关系值得深入研究。作认为，不整合面不仅是成矿热液运移的通道和储矿的空间，且是一种容易失稳的界面，在后期的构造活动演化过程中，常形成走向弯曲的拆离断层带和韧性与脆性变形并存的韧性剪切带，进而驱动矿液运移和沉淀。不整合面类型不同，矿体形态和产出特征也不同，不整合面附近多形成一些中低温热液矿床。清墟洞组是贵州铅锌、汞和铀矿的重要赋矿层位，其原因是该地层成矿元素丰度较高，地层上部有透水性低的“地球化学障”，下部有与断裂相通的“矿源层”，一般都沿深大断裂发育的背斜轴部出露。银厂坡矿床的地质地球化学特征与其附近的会泽的矿山厂、麒麟厂(超)大型铅锌矿床非常相似，预测其深部具有良好的找矿前景。

| Abstract: | It is worth studying the relationship between discordant surface and ore formation. At or near discordant surfaces, there are many kinds of mineral deposits, such as oil and gas, Au, U, Pb-Zn, Cu, Sb, and PGE. They are usually of meso-epithermal origin and have different shapes of ore-body and different occurrence features . The Qingxudong formation is an important host for Pb-Zn, Hg and U ore deposits,which generally distribute along anticlinal axes with deep faults. The Yinchangpo deposit has similar geological and goechemical characteristics to the Kuangshanchang and Qilinchang super large Pb-Zn deposits in Huize and thus has a good prospect of exploration in the deep parts of the deposit. |
