六十年代以来,地磁场在其地质历史时期曾经发生倒转的事实得到进一步的证实。以地磁极性时期表出现为标志的地磁极性世的研究,日益引起了人们的重视。利用古地磁的方法对比和划分地层,特别是划分第四纪地层在国内外已越来越广泛。第四纪地磁极性历史的研究不仅为全球性第四纪地层对比提供了可靠的依据,而且对于阐明和探索 Since the 1960s, the fact that the geomagnetic field was reversed during its geological history has been further confirmed. The research on geomagnetic polar world marked by the appearance of geomagnetic polar period table has drawn more and more people’s attention. The use of paleomagnetic methods to compare and divide the strata, especially the division of Quaternary strata, has become more and more widespread at home and abroad. Quaternary geomagnetic polarity history research not only provides a reliable basis for the global Quaternary stratigraphic correlation, but also for elucidation and exploration
