| 摘 要： | 苏丹红海州的佛地宛铁矿产于元古代中性火山岩-次火山岩的断裂带中,属于裂隙充填型铁矿床.文章通过2.5维人机交互反演和磁化率三维反演模型等方法联合解释铁矿区铁矿体地表及其深部矿体特征,通过反演结果显示出铁矿体的赋存状态、规模大小和延展深度,使高精度要磁测工作获得较好的成果.

| Abstract: | Fodikwan iron deposit occurs in a fractural zone within intermediate volcanic-subvolcanic rock belonging to fracture zone-filling type iron deposit.Inversion by 2.5-demension man-computer interaction and 3-demension modelling of suscertibility are combined to interpret characteristics of ore bodies at surface and depth and display occurrences,sizes and extension to depth of ore bo9dies and better results of high precision magnetic survey. |
