Abstract. The results of the study of two new sections of the Middle Valdai sediments of the Prinevskaya lowland using geological, geomorphological and geochronometric methods are presented. It has been established that throughout the entire Middle Valdai (50-24 thousand years ago), lake–alluvial sedimentation took place in the Prinevskaya lowland. The level of the paleobasin was at least 20 m in absolute height. Keywords: Prinevskaya lowland, middle Valdai, radiocarbon dating, OSL-dating, lacustrine-alluvial system
