摘　　要：引起航磁异常的原因有多种,对于金属矿勘查而言,研究航磁异常的意义不仅在于发现磁性矿体,不少内生金属矿床的成因及其产出位置与磁性侵入体有着密切的关系,然而,仅仅依靠磁测方法并不能解决非磁性矿体的空间定位问题。因此,多方法、多参数的综合运用势在必行。在长江中下游成矿带东段,运用大功率电法勘探技术勘查金属矿,已取得了令人鼓舞的成果。通过一个应用实例的介绍,说明方法的应用效果。In terms of metallic deposits, the significance of studying aeromagnetic anomaly was helpful to find magnetic ore bodies, the origin and occurrence of some endogenetic metallic deposits were closely related with magnetic intrusions, while magnetic survey was unable to solve the space orientation of non-magnetic ore bodies. So a synthetic use of multi-method and multi-parameters was imperative, the use of mass power electricity method to investigate the metallic deposits had received satisfactory results. The method was depicted in the text through a case analysis.
