It was established that the Late Quaternary assemblage of micromammals from the sections at kilometer 430 of the Ob River is confined to alluvium of the second terrace above the river floodplain, while the Middle Quaternary assemblage at kilometer 442 (the Khashgort locality, kilometer 440 of the Bolshaya Ob River) is associated with fluvioglacial sands showing signs of close redeposition of small mammal remains in the megaclasts contained in Middle Quaternary Khashgort boulder-bearing sandy aleuropelites.
