滨州—青岛地磁剖面地下磁性结构分析

Analysis of Underground Magnetic Structure along the Binzhou-Qingdao Geomagnetic Profile

通过探测滨州—青岛剖面的地磁总强度,获取其岩石圈磁场数据,利用延拓方法对岩石圈磁场数据进行解析延拓,并对该剖面地下磁化率结构进行分析研究。结合剖面地质构造特征,发现磁场曲线在断裂分布较复杂地段有较剧烈的起伏波动,磁化率结构在断裂处多呈高磁化率团块分布。

In this paper, through detection of the total geomagnetic intensity along the Binzhou-Qingdao profile, we obtained lithospheric magnetic field data. The lithospheric magnetic field data was extended using continuation method, and then we analyzed the underground structure of magnetic susceptibility along the Binzhou-Qingdao profile. According to the characteristics of the geological structure of the profile, it is found that the magnetic field curve has an intense fluctuation in the complicated fracture distribution area, and the magnetic susceptibility structure shows high magnetic susceptibility fraction at the fault.
