摘　　要：本文介绍了地球磁场的成因、极性变化以及运用极性倒转划分对比地层和指示环境。在实际应用中,运用古地磁极性变化和古纬度方法对二连盆地某地区地层定年和地层界面进行识别。the use of method is the Erlian This paper introduces the formation of magnetic field, polarity reversal, secular variation and geomagnetic polarity reversal or susceptibility in stratigraphic study. It is verified that this effective in dating of stratum and differentiating the boundary between two different layers in basin, northeast China.

关 键 词：磁性地层 磁极倒转 二连盆地
