GEOLOGY AND GENESIS OF THE SHUANGSANZI Ag-Pb-Zn DEPOSIT IN INNER MONGOLIA

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.
