摘要
白石岭矿区北部铅锌矿床位于沂沭断裂破碎带中段,明显受控于北北东—南南西向次级断裂破碎带,具有较大的找矿潜力。研究表明:矿体展布方向与断裂破碎带展布方向一致,具有奠定的构造控矿特征;矿区围岩蚀变较为发育,从矿体中心向两侧围岩具有“硅化、萤石化、黄铜矿化→方解石化、钾长石化”的变化规律;激电测深能够有效的反应出深部矿化蚀变带的分布规律和空间展布位置,在矿区深部找矿中具有良好的应用效果。
The Pb-Zn deposit in the northern Part of Baishiling mining area is located in the middle part of Yishu fracture zone,which is obviously controlled by the NNE-SSW secondary fracture zone,and has great potential for prospecting.The results show that the distribution direction of ore body is consistent with that of fracture zone,and has the characteristics of structural ore control.The alteration of surrounding rocks in the mining area is relatively developed.From the center of the ore body to both sides,the surrounding rocks have the change rule of"silicification,pyrolization,chalcopyrite,calcite and potash feldspathization".IP sounding can effectively reflect the distribution rule and spatial distribution position of deep mineralized alteration zone and has a good application effect in deep mining prospecting.
