Description :
Sediments of different lithological composition of a common feature, a relict system of thick syngenetic ice wedges, are called ice complexes . Three types of ice complex are distinguished in N Jakutia, with different topographic roles. They formed in the second part of the Upper Pleistocene. The A. found that it is not the matter of transportation that accounts for the formation of the main features of their composition, but the specifies of lithogenesis first of all determined by the conditions of cryogenic weathering.
