Our high-resolution data of pollen and macrofossils from 2 cores taken from the Jagodne site (Garwolin Plain) reveals a pollen succession covering the final part of the Late Saalian (Marine Isotope Stage MIS 6) and embracing the Eemian (MIS 5e). The results correspond to Regional Pollen Assemblage Zones (RPAZ). The hornbeam phase (E5 RPAZ) has been subdivided into subzones and compared to the corresponding division of the key profile of the Garwolin Plain, Kozłów K2-19. The comparison revealed a considerable sedimentary hiatus in the E5 RPAZ at Jagodne. This is attributed to significant palaeohydrological changes occurring widely in this zone, and also seen at other Eemian sites in Poland. Another specific feature of the Jagodne site is the early, rapid terrestrialisation of the palaeolake and its transformation into a raised bog, which occurred already at the end of the hornbeam phase. The Sphagnum dominated peatbog developed for a long time as evidenced by a thick peat layer covering also the Early Vistulian. Both pollen and plant macrofossil data correspond well to observed lithological boundaries, providing a consistent record of palaeoenvironmental and palaeoclimate changes. The results obtained contribute to knowledge of palaeoenvironmental changes and palaeoclimate interpretation of that area.

Jagodne 遗址(波兰中部加尔沃林平原)Eemian 间冰期演替的古植物记录

我们从 Jagodne 遗址(Garwolin 平原)采集的 2 个核心的花粉和大型化石的高分辨率数据显示,花粉演替覆盖了晚萨利安(海洋同位素阶段 MIS 6)的最后部分,并包围了伊米安(MIS 5e)。结果对应于区域花粉组合区 (RPAZ)。角树阶段 (E5 RPAZ) 已细分为子带,并与加沃林平原关键剖面的相应划分进行了比较,Kozłów K2-19。比较显示,Jagodne 的 E5 RPAZ 存在相当大的沉积中断。这归因于该区域广泛发生的重大古水文变化,并且在波兰的其他伊米亚遗址也可以看到。Jagodne 遗址的另一个具体特征是古湖早期、快速的陆地化及其转变为凸起的沼泽,这已经发生在角树阶段结束时。这泥炭占主导地位的泥炭沼泽发展了很长时间,厚厚的泥炭层也覆盖了早期维斯图尔纪。花粉和植物大型化石数据与观察到的岩性边界很好地对应,提供了古环境和古气候变化的一致记录。获得的结果有助于了解该地区的古环境变化和古气候解释。
