The cyclic structure in the Karga-Sartan Ice Complex deposits in the coastal lowlands of Northern Yakutia has been studied. The cycles of different genesis (cryolithological, structural, lithological, soil-vegetational) and duration have been analyzed. It is demonstrated that the climate fluctuation were the major factor of cyclic structure in the Ice Complex deposits. It has been revealed that the cyclic characteristics of the Ice Complex can become apparent both in subaqueous and in subaerial facies of Ice Complex. The conclusion has been made about the crucial role of the cryogenic weathering and subsequent re-deposition of eroded soils in river valleys and alas depressions in the formation of the Ice Complex.
