摘　　要：野外地质调查表明,会东县麦地区内铅锌异常范围内麦地坪组下、底部层位已经发现较具规模的铅锌矿化体,为了进一步查明矿化体的延伸及矿化情况,在矿区开展了1∶10 000的频率域激电扫面工作,通过激电异常特征,大致圈定了区内矿体的分布范围;同时,通过瞬变电磁法基本探明了控矿层间破碎带的埋藏深度,为下一步找矿工作的开展提供了有力地球物理依据。Base on field geological survey,medium scale lead-zinc mineralized body has been found under Maidiping group in Maidi deposit of Huidong province.In order to further identify the extension and mineralization of the mineralized body,1：1million IP work has been done.And distribution range of ore bodies has been determined by exception feature of IP,at the same time,we have determined the interstratified fractured buried depth by TEM method.A powerful geophysical basis for the development of mineral exploration work has been provided.
