Cold continental climate in Siberia determines peculiar conditions of glacier formation and dynamics. Interacting with permafrost, they become a new element of cryodiversity, i. e. a set of objects and phenomena produced by cold, and differ greatly from the glaciers which are considered from the classical positions of the Alpine glaciation model. On cooling down to quite low temperatures (far below 0 °С), the glaciers in Siberia acquire traits which are more inherent for the permafrost rather than for Alpine-type glaciers. The acquired feature calls for regarding the formed aggregation of glaciers and permafrost as peculiar geosystems; the authors name them cryolithogenic-glacial systems.
