О границе плейстоценовых оледенений в бассейне верхнего и среднего течения р. Колымы

Аннотация

On the basis of glacial erosion landforms and hypsometric position of glacial deposits of different age 5 Pleistocene glaciations were identified at the Central Kolyma Upland, glaciers thickness and length having been estimated. Younger glaciations are established to be of valley type, older ones - to be semi-ice sheets and ice sheets type. Height of the lower limit of the glaciers' alimentation zone during the 5 ice ages were 1600-1850, 1400-1600, 1350-1450, 1100-1400 and 850-950 meters respectively.
