摘　　要：为寻找隐伏矿产和确定矿化中心等,进一步缩小异常范围,为工程设计提供依据,在勘查区开展大功率激电中梯(短导线)剖面测量工作。推测勘查区激电异常方向近南北向,与含矿构造带走向一致,该构造带是本区金及多金属矿赋存部位,经钻探工程验证,印证了激电异常是寻找金及多金属矿的有效方法之一。In order to find hidden minerals and determine the mineralization center,further reduce the abnormal range and provide the basis for engineering design,high power IP intermediate gradient(short conductor)profile survey was carried out in the exploration area.It is speculated that the direction of induced polarization anomaly in the exploration area is nearly north-south,which is consistent with the trend of ore-bearing structural belt,while the structual belt is the occurrence place of gold and polymetallic deposits in the area.The drilling engineering verification shows that IP anomaly is one of the effective methods to search for gold and polymetallic deposits.
