This project is a contribution to the ICDP funded drilling project at Lake El´gygytgyn, a lake located in a 3.6 Ma old meteorite impact crater in north-eastern Siberia. The initiative aims drilling of the impact rocks and overlying lake sediment succession to reconstruct the impact event and the Late-Pliocene and Quaternary climatic and environmental history. As part of a pre-site survey for the drilling campaign, sediment samples were recovered in 2003. While the first months of this DFG-project mainly focused on the lake history during the last 340 ka, the second year will approach a detailed record of the Holocene and the Last Glacial Maximum. Additionally, a newly recognised problem, dealing with the formation of cold stage sediments, has to be solved. The understanding of these sedimentation processes is crucial for further investigations of older lake sediments that will be obtained by the ICDP-drilling Project.

该项目是对ICDP资助的El'gygytgyn湖钻探项目的贡献，该湖位于西伯利亚东北部一个3.6 Ma的陨石撞击坑中。该倡议旨在钻探撞击岩石和上覆湖泊沉积物序列，以重建撞击事件以及上新世晚期和第四纪气候和环境历史。作为钻探活动现场前调查的一部分，2003年采集了沉积物样本。虽然这个DFG项目的前几个月主要集中在过去340万年的湖泊历史，第二年将接近全新世和末次冰期最大的详细记录。此外，一个新认识的问题，处理冷阶段沉积物的形成，必须解决。这些沉积过程的理解是至关重要的，为更古老的湖泊沉积物，将获得的ICDP钻探项目的进一步调查。
