英文摘要	Four stages of massive ice lens and three levels of cryopegs have been studied in the Holocene sediments near the Sabetta settlement. Contrast vertical and lateral distribution of δ18O values in multi-stage massive ice near the Sabetta and Gyda estuaries provides the basis for the allocation of the isotopic composition as indicator type for the segregated or infi ltration segregated multi-stage ice formations and their intra-sedimental origin. The ratio of the chloride and sulfate anions, pollen spectra and presence of algae in the ice of different types in the Sabettayakha estuary suggest that vertically layered brown ice had been accumulated during freezing of water saturated sands of the Ob Gulf; the brown non-laminated ice had been formed as a result of freezing of underlake talik water; the origin of the white ultra-fresh ice could also be linked with the lake and river waters. It has been demonstrated that massive ice occurrs both in pre-Quaternary deposits and in modern and Holocene sediments.
