During the construction of the S-3 road near Gorzów Wielkopolski, a sedimentary succession of the Eemian Interglacial and the older part of the Weichselian Glaciation were exposed. The succession, ~22 m thick, consists of lacustrine and fluvioglacial deposits. Lake sediments, mainly calcareous gyttja with peat intercalations, represent the infills of two palaeolakes. The almost complete skeleton of a forest rhinoceros, Stephanorhinus kirchbergensis, and a bone of the fallow deer Dama dama were found in the older lake deposits. Mollusc shells were numerous in both lake sequences, analysis of which revealed two types of assemblage, representing the coastal, littoral zone of a shallow lake with a muddy bottom. The sequence of mollusc communities observed in vertical succession allowed reconstruction of environmental changes during deposition. Several hydrological changes have been recognized within the palaeolake, especially water level fluctuations probably due to climate change.

Gorzów Wielkopolski(波兰西北部)湖泊沉积物的软体动物群作为伊米期和魏克塞尔期早期环境变化的指标

在 Gorzów Wielkopolski 附近的 S-3 公路建设期间,Eemian 间冰期的沉积序列和 Weichselian 冰川的较旧部分暴露出来。层序约 22 m 厚,由湖相和河冰沉积物组成。湖泊沉积物,主要是带有泥炭夹层的钙质 gyttja,代表了两个古湖泊的填充物。几乎完整的森林犀牛骨架,Stephanorhinus kirchbergensis和小鹿Dama dama的骨头发现于较旧的湖泊沉积物中。两个湖泊序列中的软体动物贝壳数量众多,对其进行的分析揭示了两种类型的组合,代表了底部泥泞的浅湖的沿海沿岸地区。在垂直序列中观察到的软体动物群落序列允许重建沉积过程中的环境变化。在古湖中已经发现了几种水文变化,特别是可能由于气候变化引起的水位波动。
