In-Depth Information
In Russia there are a large number of soil classifi cation systems that differ
signifi cantly among each other. Not all soils containing permafrost are classifi ed
as the equivalent of cryosols in Russia (Mazhitova
2004
). Soils that are strongly
cryoturbated are classifi ed as cryozems; these soils normally have a shallow
active layer.

as interpretation by Mazhitova (
2004
). Gelisol great groups in ST are comparable to
