摘要

本文介绍了对立陶宛南部内穆纳斯河中游末期冰川沉积(晚内穆纳斯期、晚魏氏期)的沉积物进行的沉积学和古植物学研究。研究人员分析了二迭层(冰川淤积层)之间的夹层沉积物中的孢子、花粉和其他古植物形态,并利用现代模拟技术(MAT)评估了其沉积过程中的古地理和古气候条件。末次冰川时期的两个冰碛层在成分上存在显著差异,证明了该地区冰川运动路径的不同。冰川堆积层之间的连续沉积过程为末次冰川时期的全球气候变化以及斯堪的纳维亚冰原东南部脱冰期的冰川裂片重组提供了证据。沉积过程和植被组成见证了开阔的草原-苔原地貌、零星的林区,以及之后出现的嗜热植被,表明年温度升高,湿度增大。根据现有的数据,可以确定巴尔比耶里什基斯阶段间期属于晚内穆纳斯冰川期(上内穆纳斯地层),介于地区第四纪地层方案中的格鲁达阶段和巴尔蒂亚阶段(格鲁达和巴尔蒂亚子地层)之间。这一时期与海洋同位素第二阶段(MIS 2)相关。

Stadial and interstadial deposits of Late Nemunas (Late Weichselian/MIS 2) glaciation in south Lithuania and their interpretation

This paper presents sedimentological and paleobotanical studies of the deposits from Last Glaciation (Late Nemunas, Late Weichselian) in the middle reaches of the River Nemunas in southern Lithuania. Spores, pollen, and other palynomorphs in the intercalated sediments between the diamicton (glacial till) beds were analyzed, and the paleogeographical and paleoclimatic conditions of their sedimentation were assessed using the modern analog technique (MAT). The two till layers from the Last Glaciation, characterized by significant differences in their composition, testify to a difference in glacier movement paths in the region. The continuous sedimentation process between glacial tills provides evidence of global climate changes during the Last Glaciation and the restructuring of glacial lobes during deglaciation in the southeastern part of the Scandinavian Ice Sheet. The sedimentation process and vegetation composition bear witness to an open landscape of steppe-tundra, scattered wooded areas, and the emergence of thermophilic vegetation afterward, suggesting increased annual temperatures and higher humidity. The available data enable the identification of the Balbieriškis interstage period within the Late Nemunas Glaciation (Upper Nemunas Formation) between the Grūda and Baltija stages (Grūda and Baltija subformations) in the regional Quaternary stratigraphic scheme. This period correlates with the Marine Isotope Stage 2 (MIS 2).

期刊介绍: Quaternary International is the official journal of the International Union for Quaternary Research. The objectives are to publish a high quality scientific journal under the auspices of the premier Quaternary association that reflects the interdisciplinary nature of INQUA and records recent advances in Quaternary science that appeal to a wide audience. This series will encompass all the full spectrum of the physical and natural sciences that are commonly employed in solving Quaternary problems. The policy is to publish peer refereed collected research papers from symposia, workshops and meetings sponsored by INQUA. In addition, other organizations may request publication of their collected works pertaining to the Quaternary.
