| 中文摘要: |
| 文章通过地面高精度磁法面积测量工作,圈定6处具有较大规模的地磁异常,编号为DC1~DC6。通过典型剖面2.5D磁化率反演,推断的磁性体与地质工程实际控制的磁铁矿体位置基本吻合,产状基本相近。通过磁法3D磁化率反演计算,基本搞清了高磁化率磁性体在深部空间的分布范围、分布面积、延深等情况,为后续地质找矿工作指明了方向。 |
| 英文摘要: |
| In this thesis, we conduct a series of high-precision ground magnetic surveys in this area, Our studies reveal six large-scale magnetotelluric anomalies, indexing from DC1 to DC6. Geological surveys show that our inversion results are in good consistency with the real positions and orientations of the magnetite ore bodies. In addition, we conduct a 3D magnetic susceptibility inversion, and provide a preliminary estimation of the range, the distribution area and the thickness of some high magnetic susceptibility bodies in deep of the underground. Our studies should be considered as the target region for future exploration of blind magnetite ores. |
