Abstract A correlation of stratigraphic subdivisions of the late Middle Pleistocene (MIS 12-6) in central Europe is extremely difficult, because of abundant hiatuses. Therefore, the site Rechitsa in western Belarus is extremely important for a regional stratigraphy, because of its well documented sediments of the Alexandrian Interglacial (Holsteinian; MIS 11) and a crucial palaeoclimate and palaeoenvironmental record of the Middle Pleistocene. The sequence starts with proglacial delta deposits formed at the termination of the Berezinian Glaciation (Elsterian; MIS 12), overlain by organic deposits of the Alexandrian Interglacial (Holsteinian; MIS 11) and the early glacial cooling of the Pripyatian Glaciation (Saalian). The hiatuses in MIS 10, 9 and 7 are interrupted by occasional occurrence of a periglacial lake, accompanied with open vegetation communities in MIS 8, characteristic by alternate temperate and cold episodes with significant climate-induced environmental transformations with extremely cold and dry conditions recorded by huge frost wedges with primary infilling. Extremely severe climatic conditions of MIS 6 favoured development of huge frost wedges with primary infilling, overlain by sediments of a periglacial lake. The Rechitsa section was overbuilt by glaciofluvial and aeolian deposits during the Pripyatian Glaciation (Saalian). The recorded huge hiatuses in MIS 10, 9 and 7 are common in central Europe represent presumably arid conditions and lack of deposition. The sedimentary sequence at the site Rechitsa is an important link of central and eastern European stratigraphic subdivisions of the Middle Pleistocene.

白俄罗斯西部 Rechitsa 中更新世矿床及其对中欧 MIS 12-6 地层的输入

摘要 由于大量间断，中欧中更新世晚期 (MIS 12-6) 地层细分的相关性极其困难。因此，白俄罗斯西部的 Rechitsa 站点对于区域地层学极为重要，因为它有充分记录的亚历山大间冰期（荷尔斯泰因；MIS 11）沉积物和中更新世的重要古气候和古环境记录。该序列始于在别列津冰川（Elsterian；MIS 12）结束时形成的前冰期三角洲沉积物，上面覆盖着亚历山大间冰期（Holsteinian；MIS 11）的有机沉积物和普里皮亚季冰川（Saalian）的早期冰川冷却。MIS 10、9 和 7 的中断被偶尔出现的冰缘湖打断，伴随着 MIS 8 中的开放植被群落，其特征是温带和寒冷交替发生，气候引起的环境变化显着，极端寒冷和干燥的条件由具有主要填充物的巨大霜楔记录。MIS 6 极端恶劣的气候条件有利于形成具有初级填充物的巨大霜楔，其上覆有冰缘湖的沉积物。Rechitsa 部分在普里皮亚季冰川（Saalian）期间被冰川河流和风积沉积物过度建造。MIS 10、9 和 7 中记录的巨大中断在中欧很常见，这可能代表干旱条件和缺乏沉积。Rechitsa 遗址的沉积层序是中更新世中欧和东欧地层细分的重要纽带。以温带和寒冷交替出现的特征为特征，具有显着的气候引起的环境转变，极端寒冷和干燥的条件由具有主要填充物的巨大霜楔记录。MIS 6 极端恶劣的气候条件有利于形成具有初级填充物的巨大霜楔，其上覆有冰缘湖的沉积物。Rechitsa 部分在普里皮亚季冰川（Saalian）期间被冰川河流和风积沉积物过度建造。MIS 10、9 和 7 中记录的巨大中断在中欧很常见，这可能代表干旱条件和缺乏沉积。Rechitsa 遗址的沉积层序是中更新世中欧和东欧地层细分的重要纽带。以温带和寒冷交替出现的特征为特征，具有显着的气候引起的环境转变，极端寒冷和干燥的条件由具有主要填充物的巨大霜楔记录。MIS 6 极端恶劣的气候条件有利于形成具有初级填充物的巨大霜楔，其上覆有冰缘湖的沉积物。Rechitsa 部分在普里皮亚季冰川（Saalian）期间被冰川河流和风积沉积物过度建造。MIS 10、9 和 7 中记录的巨大中断在中欧很常见，这可能代表干旱条件和缺乏沉积。Rechitsa 遗址的沉积层序是中更新世中欧和东欧地层细分的重要纽带。
