摘　　要：叶家庄矿区地形陡峭、接触带形态复杂、矿体埋深较大,常规的物探方法无法满足目前的勘探要求。CSAMT具有勘探深度大、分辨率高、受地形影响和高阻层的屏蔽作用小,在深部找矿中发挥着重要的作用。在综合分析了矿区地质情况、施工条件及物性参数的基础上,选择开展了CSAMT法勘探,成功圈定了接触带的位置、形态和成矿有利部位,经钻孔验证见多层铜矿体,累计厚度61.99米,说明了CSAMT方法在该地区铜矿勘查中的有效性,可为该地区寻找矽卡岩型铜矿提供指导和借鉴。Because of steep terrain,complex contact zone shape and large buried depth of orebody,conventional geophysical exploration methods can not meet the current exploration requirements in the Yejiazhuang mining area.CSAMT plays an important role in deep prospecting due to its large exploration depth,high resolution,small shielding effect by topography and high resistivity layer.Based on the comprehensive analysis of the geological conditions,construction conditions and physical parameters of the mining area,the CSAMT exploration method has successfully delineated the position,shape and favorable ore-forming position of the contact zone.The multi-layer copper body with a cumulative thickness of 61.99 m was found in the borehole verification,which shows the effectiveness of the CSAMT method in the copper exploration in this area,and can provide guidance and reference for the search of skarn type copper deposit in this area.
