| 摘 要： | 本文通过冀中北部地区高精度航磁局部异常与盖层断层对应关系之实例,经与地震资料对比及正演拟合计算,着重分析研究了盖层断层引起局部磁异常的条件、特征及地质因素,从而提出了利用高精度航磁资料确定盖层断层的可能性及划分原则与方法。本文还指出,串珠状微弱局部磁异常带与盖层断层十分吻合的事实,为高精度航磁确定盖层断层提供了重要依据。

| Abstract: | Based on correlation between high-predsion aeromagnetlc local allomallesand faults in covenng strata In nortlleffi part of centralHchel and through acomparison witll seismic data and direct fitting calctilation, this paper makesa detdlodanalysls of tile prerequlsite and geologicaf factors with which thefaults in covering strata may arollse local magnetic atomanelies,and thus indi-cates the posslbility of using high-precision aeromanetic data to detect faultsIn covedng strata as wu asdle prlncl“es and methods for division. It is alsopointed out in this paper that the perfect coincidence betwee the clusteredweak local magnetic anomalous zones and the faults In covering strata willprovide lmportant basls for using high-precision aelomagnetic survey ln deter-mining faults In covering strata. |
