Despite years of research, Lower Triassic deposits of the epicontinental Central European Basin still lack a detailed stratigraphy that would allow regional correlation of isochronous horizons. The best chronostratigraphic results have up to now been achieved by microspore-based biostratigraphy and magnetostratigraphy. Integrated palynostratigraphic and magnetostratigraphic investigations, carried out on Buntsandstein cores from northeastern Poland representing the eastern margin of the basin, have made precise correlations with the better-explored basin centre. The Lidzbark and Malbork formations of the Bartoszyce IG 1 borehole were examined by means of palynology and palaeomagnetic studies. Further palaeomagnetic studies were applied to the Lidzbark, Malbork and Elbląg formations of the Nidzica IG 1 borehole and the Elbląg Fm. of the Pasłęk IG 1. Two spore-pollen assemblages were distinguished representing the Densoisporites nejburgii Subzone of the D. nejburgii Zone within the lower part of the Lidzbark Fm. and the lowermost part of the Malbork Fm. Mostly reversed polarity was detected within the lower part of the succession investigated, whereas normal polarity prevailed within its upper part. A normal polarity local zone was correlated with the undivided Tbn6–Tbn7 standard magnetozones of western Poland. The reversely polarized part of the succession corresponds most probably to the Tbr5 standard magnetozone. The base of the Tbn6–Tbn7 magnetozone can serve as a good correlation horizon for regional reconstructions.

尽管进行了多年的研究，中欧陆上盆地的下三叠纪沉积物仍缺乏详细的地层学，以使等时层位区域相关。迄今为止，通过基于小孢子的生物地层学和磁地层学已经取得了最好的年代地层学结果。在代表该盆地东部边缘的波兰东北部的Buntsandstein岩心上进行的古地层和地磁综合调查，已将其与勘探较好的盆地中心精确地联系起来。Bartoszyce IG 1钻孔的Lidzbark和Malbork地层通过古生物学和古磁研究进行了研究。进一步的古地磁研究已应用于Nidzica IG 1井眼和ElblągFm的Lidzbark，Malbork和Elbląg地层。PasłękIG 1。D的Densoisporites nejburgii子区域。nejburgii区域位于Lidzbark Fm的下部。以及马尔堡Fm的最下部。在所研究的演替序列的下部中检测到的极性反转最多，而在其上部则检测到正常极性。正常极性的局部区域与波兰西部未划分的Tbn6-Tbn7标准磁区相关。序列的反极化部分最可能对应于Tbr5标准磁区。Tbn6-Tbn7磁区的基础可以作为区域重建的良好相关层。
