摘　　要：山东省某铜矿区位于莱芜铜矿成矿远景重点勘查区北部,为查明该区域铜矿体空间分布特征,开展了激发极化法测量工作,并结合区内地质资料、岩矿石特征及已有钻井资料对取得的测深剖面进行了分析解译。通过以上工作确定了铜矿体主要赋存于沿河流发育的区域构造内部,沿构造走向呈串珠状发育,具有一定尖灭再现特征,取得了较好的找矿效果,表明激发极化法在该地区铜矿勘查中是合理有效的物探方法。A copper mine in Shandong province is located in the northern part of the prospecting area of the Laiwu copper deposit,in order to find out the spatial distribution characteristics of copper ore bodies in the area,the method of induced polarization measurement is carried out,and combined with the geological data in the area,rock and ore features and existing drilling data to obtain a bathymetric profile in the analysis and interpretation.Through the above work to determine the copper ore bodies mainly occur along the river development of regional internal structure,along the tectonic to was beaded development,reproduction characteristics with certain annihilation and achieved better find mine,indicating that the induced polarization method in the exploration in the mine is reasonable and effective geophysical method.
