The conditions of forming of the cryohydrochemical structure of the deposits of marine plains, including the repeatedly injected massive ice beds, the ion-saline composition and the mineralization of the massive ice beds in the layers of one stratum, the dependence of the ion-saline composition of the massive ice beds upon the degree of their mineralization, the chemical composition and the share of various kinds of natural waters in the formation of massive ice beds, and the reasons of change of their initial chemical composition have been examined sequentially. It has been demonstrated that in the severe climatic and geocryological conditions of Yamal the lakes were the exclusive sources which could provide the regular entry of the enormous volumes of ultra-fresh water into the stratum of frozen marine deposits. The hydrochemical similarities of the chemical composition and the mineralization of the repeatedly injected massive ice beds and lake water have been proved.
Key words: Repeatedly injected massive ice beds, chemical composition of ice and natural waters, cryohydrochemical structure of the stratum of marine deposits.
