摘要

本文介绍并讨论了在Brześc Kujawski IG-1钻孔(波兰中部)中Buntsandstein剖面钻探的新磁地层资料。文中还讨论了Buntsandstein特殊地层的年代地层位置。从Brześc Kujawski IG-1井中获得的磁极模式与早先在中欧盆地波兰部分的其他井中获得的模式相匹配。尽管磁地层学和孢粉学证据毫无疑问地表明，CEB波兰部分的Induan/Olenekian边界位于波美拉尼亚组的下部，但Olenekian/Anisian边界在中欧盆地沉积序列中的位置仍然存在问题。根据孢粉学研究，这一边界很可能位于upper Buntsandstein的上部。

Buntsandstein magnetostratigraphy in Poland: new data from the Brześć Kujawski IG-1 borehole

New magnetostratigraphic data from the Middle Buntsandstein section, drilled in the Brześc Kujawski IG-1 borehole (Central Poland), are presented and discussed. The chronostratigraphic positions of particular formations of the Buntsandstein are discussed as well. The magnetic polarity pattern obtained from the Brześc Kujawski IG-1 borehole matches the pattern obtained earlier in other boreholes from the Polish part of the Central European Basin. Although magnetostratigraphy and palynological evidence undoubtedly indicates that the Induan/Olenekian boundary in the Polish part of the CEB is located in the lower part of the Pomerania Formation, the placement of the Olenekian/Anisian boundary within the sedimentary sequences of the Central European Basin remains problematic. This boundary most probably is located within the upper part of the Upper Buntsandstein, as can be inferred from palynological studies.
