吉林省白山地区磁异常解释推断

Interpretation of magnetic anomaly in baishan region of jilin province

针对物探具有多解性,磁法测量也同样具有多解性,重点阐述总场与垂直分量之间转换,理论曲线与实际曲线之间的对比,剖面曲线向下延拓合理运用,与地质结合成功解释磁异常曲线,推断出引起磁异常的地质原因及磁性体的埋藏深度、产状、形状、磁性等,并从理论上解释了某剖面为何北部没有出现负异常的原因。

In view of the problem that the physics exploration has multi-solution,the measurement by magnetic method has also multi-solution.the paper intensive expounds the conversion between the total field and vertical component,the comparison between the theoretical curve and active curve,the application rationality of downward continuation of the section curve,and it is combined with geology to explain abnormal curve of magnetism triumphantly,the characteristic of this paper is that explans why the north of NO.1 section hasn’t negative anomaly in theory.
