GEOLOGY AND GENESIS OF THE SHUANGSANZI Ag-Pb-Zn DEPOSIT IN INNER MONGOLIA
-
摘要: 双山子区位于乌兰浩特-巴林右旗铜多金属成矿带的南西端，目前共发现有5条银铅锌盲矿体.区内银铅锌矿体主要受早期北东东向断裂构造所控制，铅锌矿（化）体具有集中分布于火山碎屑角砾岩内及其边部的特征，矿床属于岩浆热液型矿床成因.区内呈北东东向以不规则状出现的物探激电异常、中低视电阻率异常与△T磁异常及较高浓度Ag、Cu、Pb、Zn、As等元素的土壤异常分布区，是本区重要的找矿信息和标志.Abstract: The Shuangsanzi area is located in the southwest end of the Ulanhot-Balinyouqi Cu-polymetal metallogenic belt, where five Ag-Pb-Zn blind orebodies have been found. The orebodies are mainly controlled by the early NEEtrending faults and intensively distributed in and around the pyroclastic breccia. The deposits genetically belong to magmatic hydrothermal type. They occur in a zone of NEE direction, with irregular-shaped geophysical anomaly and rich Ag, Cu, Pb, Zn and As soil anomaly. All of those are important prospecting information and indicators in the area.
