摘　　要：周格庄多金属矿化带位于山东海阳周格庄东部,区内中生代地层广泛分布,中生代岩浆岩活动频繁,构造活动强烈、破碎带发育。激电异常明显且低阻高激化特征,多金属矿化期为岩浆期后热液阶段。岩体边部和外侧的断裂破碎带为成矿热液运移、储存提供了有利空间,是寻找多金属矿的有利部位。Polymetallic mineralized belt in Zhougezhuang area is located in the east of Zhougezhuang town of Haiyang city in Shandong province.Mesozoic strata are widely distributed in this area.Mesozoic magmatic 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 mineralization 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 for prospecting multimetallic deposits.
