山东省兰陵县车辋地区铜铅多金属矿地质特征及找矿标志

Geological Characteristics and Prospecting Symbols of Copper Lead Polymetallic Deposit in Chewang Area of Lanling County in Shandong Province

车辋地区铜铅多金属矿区位于山东省兰陵县车辋镇东部,区内寒武-奥陶纪碳酸盐岩地层分布广泛,中生代岩浆活动频繁,构造活动强烈、层间破碎带发育。激电异常明显,且具低阻高极化特征。铜铅多金属矿化期为岩浆期后热液阶段,岩体边部和外侧的构造破碎带、层间破碎带为成矿热液的运移、储存提供了有利空间,是寻找多金属矿的有利部位。

Copper lead polymetallic deposit in Chewang area is located in east of Chewang town of Lanling county in Shandong province. Cambrian - Ordovician carbonate rock strata are widely distributed in this area. Mesozoic mag- matic activities are frequent, tectonic activities are stong and interlayer fractural belts developed well. The induced polarization is obvious and has low resistance and high polarization characteristics. Copper lead polymetallic miner- alization stage is the hot liquid phase of the magma period. Structural fracture belts in the outer and outside of the rock mass provide a favorable space for migration and storage of the ore forming hydrothermal fluid. It is favorable position for prospecting multi - metallic deposits.
