摘要
在航磁调查工作中,为了追踪隐伏断裂、隐伏岩体及隐伏矿体,尝试了应用方向导数、斜导数和插值切割法等方法。针对建立的理想模型进行对比分析,并在内蒙古某地进行实验,认为应用斜导数追踪隐伏断裂、隐伏岩体,参考插值切割法追踪隐伏磁铁矿体方法较好。
In order to track buried faults, rocks and ore bodies, the authors tentatively applied the directional derivative, tilt derivative and interpolation-cut method as well as some other methods for airborne magnetic survey, and then created a model for comparative analysis in Inner Mongolia. In the application of the tilt derivative to track concealed faults and rock bodies, the interpolation-cut method for tracking concealed magnetic ore bodies seems to be comparatively satisfactory.
