| 1 | This article introduces the information about the absolute age of the relict bog, situated in the poligonal bogs zone (in the south of Gydan peninsula). It is established that this bog isn’t «relic», because it was formed in Holocene. The comparison of peat accumulation of this bog and of oligotrophic bogs was organized and some particular qualities of peat accumulation in the evolution of «relict» peatlands were identified. Also the article presents the botanical composition of the peat deposit of the object of study. The comparison of the Holocene climatic variations on Russian Plane and in Western Siberia for the oligotrophic bogs zone is considered. It is proved that for the reconstruction of climatic variations for the «relict» peat deposit in the Far North regions it’s necessary to consider the inertness of cryogenic processes.
