Facies logs and age determinations of 8 sites from Taymyr Peninsula

The Taymyr Peninsula constitutes the eastern delimitation of a possible Kara Sea basin ice sheet. The existence of such an ice sheet during the last global glacial maximum (LGM), i.e. during the Late Weichselian/Upper Zyryansk, is favoured by some Russian scientists. However, a growing number of studies point towards a more minimalistic view concerning the areal extent of Late Weichselian/Upper Zyryansk Siberian glaciation. Investigations carried out by us along the central Byrranga Mountains and in the Taymyr Lake basin south thereof, reject the possibility of a Late Weichselian/Upper Zyryansk glaciation of this area. Our conclusion is based on the following: Dating of a continuous lacustrine sediment sequence at Cape Sabler on the Taymyr Lake shows that it spans at least the period 39-17 ka BP. Even younger ages have been reported, suggesting that this lacustrine environment prevailed until shortly before the Holocene. […]

泰梅尔半岛构成了可能卡拉海冰盖的东部边界。一些俄罗斯科学家认为，在最后一次全球冰期极值（即晚维士尔期/上祖里扬斯克期）期间存在这样的冰盖。然而，越来越多的研究倾向于对晚维士尔期/上祖里扬斯克期西伯利亚冰川分布范围的简约视角。我们在中央比扬甘山脉及其以南的泰梅尔湖盆地区进行的调查否定了该区域存在晚维士尔期/上祖里扬斯克期冰川的可能性。我们的结论基于以下事实：对泰梅尔湖萨布勒角连续湖相沉积序列的定年显示，其时间跨度至少为公元前39-17千年。还有更年轻的年代数据被报道，表明这一湖泊环境一直持续到全新世前夕。...
