对取自南黄海中部泥质区的NHH01孔进行了高分辨率的古地磁研究,结果显示在4.26～3.84m为一地磁场反极性漂移。结合钻孔在4.59m处和5.69m处的AMS~(14)C测年校正值分别为10200aB.P.和13500aB.P.以及岩芯的沉积特征,认为其在该时段为相对稳定的海相沉积。线性外推该反极性漂移的年限为9470～8540aB.P.,可能是哥德堡反极性漂移在该沉积物中的记录。这就为地磁场在全新世初期发生过漂移提供了一个新的佐证,同时也为该区晚更新世以来地层的进一步精细划分和对比提供了一个标志。
High-resolution palaeomagnetic studies on NHH01 pores taken from the muddy area in the central part of the southern Yellow Sea show that the magnetic field has a reverse polarity drift of 4.26 ~ 3.84m. The correction of AMS ~ (14) C dating at 4.59m and 5.69m in boreholes was 10200aB.P. and 13500aB.P., respectively, and the depositional characteristics of the core, which were considered as relatively stable in this period Phase deposition. The linear extrapolation of the reverse-polarity drift is from 9470 to 8540 aB.P., probably the result of a Göteborg reverse polarity drift in the sediment. This provides a new evidence for the geomagnetic field drifting during the early Holocene, and also provides a mark for further fine division and comparison of strata in the area since the late Pleistocene.
