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.
