| 摘 要： | 通过河南邙岭塬北缘中部,孟津扣马黄土剖面野外观测及室内磁化率研究,剖面共发育11层(S1~11)以上黄土-古土壤序列,各层古土壤清晰;但第二层(S2)的磁化率值相对较低,而且与第三层(S3)间所夹黄土层非常薄,显示异常特征。古地磁测试结果揭示,B/M界限在深度38.9m处,位于L8的底部。松山负极性时晚期,记录了两段正极性。

| Abstract: | In this paper,Kouma profile,located in Mengjin,Henan north of middle Mangling Plateau Form has been studied.This profile contains S11 and upwands loess-paleosol each loess and paleosol are clear.The magnetic susceptibility curve shows that the susceptibility value of S2 is lower than the others,while the thickness of L3 is very thin,showing abnovmal character.Palaeomagnetic stratigraphy shows that the depth of the boundary between Brunhes normal polarity chron and Matuyama reversed one is 38.9 meters,which located at the lower part of L8.Furthermore,two normal polarity intervals are revealed in the late Matuyama reversed polarity chron. |
