Abstract

Lithological features of intermoraine aquatic sediments were studied to assess the possibilities of their application for the stratigraphic subdivision and correlation, as well as paleogeographic reconstructions and localization of the terrigenous provenances during the formation of these sediments. Results of the lithological study of Quaternary aquatic sediments in the European subarctic part of Russia represented by various genetic types of sediments, often with very specific features, are presented. Based on the textural and structural characteristics in the Neopleistocene sequence, alluvial, lacustrine, fluvioglacial, and limnoglacial sediments are revealed.

东欧北部平原第四纪水生沉积物的岩性和形成条件

摘要

研究了间期水生沉积物的岩性，以评估其在地层细分和相关以及在这些沉积物形成过程中古地理重建和陆源物定位方面的可能性。介绍了俄罗斯欧洲北极地区第四纪水生沉积物的岩性研究结果，这些沉积物以各种遗传类型的沉积物为代表，通常具有非常特殊的特征。根据新世新世序列的质地和结构特征，揭示了冲积，湖相，河冰和河冰沉积物。
