摘　　要：四川攀西地区某钒钛磁铁矿区位于安宁河、攀西深断裂钒钛磁铁矿含矿带上,地面磁测圈定T2异常,对经过该异常的A-A′精测剖面进行2.5D人机交互反演。反演结果不仅为确定验证钻孔的施工位置起到了关键作用,而且推断了地下可能存在的磁性异常体及有利的成矿部位,为下一步的地质勘探工作提供地球物理依据。A vanadium - titanium magnetite （V - Ti magnetite） area of Panxi region is loca- ted near Anning River, and on the Panxi deep fault belt which contains V - Ti magnetite ore. This paper delineates T2 abnormalities through ground magnetic survey, and makes 2. 5D inversion in human - computer interaction on the abnormal profile of A-A＇. The inversion results play key roles not only in verifying the location of drilling, but also in deducing the ground magnetic anomalies and favorable ore bodies so as to provide available geophysical basis for the next geological exploration work.
