Abstract: The study is devoted to the late Pleistocene-Holocene paleogeography of the central part of the Gydan Peninsula in the area of the Parisento. The work covers the results of field studies in the area of Lake Parisento and in the middle reaches of the Gydansky Yuribey. The study is based on field data, radiocarbon and OSL - dating and correlation with data from previous studies. It was established that in the lower part of the sections, Kazan-Early-Zyrian (MIS 5-4) dark gray loams and sandy loams outcrop. Above lie the Kargin-Sartan (MIS 3-2) lacustrine, or lacustrine-alluvial gray horizontally and cross-stratified sands that make up the surface at elevations of 20-30 m in the vicinity of Lake Parisento. Kargin-Sartan (MIS 3-2) alluvial light-gray fine-grained sands with wave lamination interbedded with dark-gray sandy loams and loams were found on the right bank of Yuribey River in the southeast of the area. Above are the Sartan (MIS 2) and Holocene gray cover sandy loams and loams. They lie at the top of the sections at elevations of 40-50 m. Holocene peats are encountered on top of the sections at various geomorphological levels.
