| 摘 要： | 高精度磁测是一种直接寻找磁铁矿的有效方法，但由于磁法存在纵向分辨率低的缺点，浅部磁性变化往往又对磁异常影响很大。本文结合矿区地质资料，依据矿区物性参数、成矿模式，使用2．5D剖面人机交互正反演技术对矿区内几个典型的磁异常进行定量反演，结合对矿区铁矿情况进行了定量分析，为矿区进一步工作提供了依据。

| Abstract: | It is an effective method to detect the magnetic iron by high--precision magnetic survey. But because of low along track resolution, the alternation of superficial magnetic field has a great effect on magnetic anomaly. Considering the geological data, physical property and mineralization model of this mining field, this paper inverses several typical magnetic profiles quantitatively by 2.5D Man--computer forward and inversion technology, and analyzes the iron--ore deposits. These researches provide meaningful referential data for further work in the ore area. |
