Abstract

N.V.Kind (1974) has found in the Yenisei lower reaches the moraines of all four stages of Sartan glaciation. Then the authors of (Astakhov et al., 2016) have shown, that all the moraines, which were earlier attributed as Sartan glaciations structures, are pre-Sartan ones; with Sartan moraines being found to lie at the Kara sea bottom. In the light of these data, the assignment of the marks of eight glaciation stages in the Aksor Lake area (Zykyn et al., 2003) may seem to be strange. Actually, the Aksor Lake is located already in the mountains, between offsets of the Ulbin and Kalbin ranges, and the geological section studied in (Zykyn et al., 2003) reflects the eight stages of the latest mountain glaciation of the Altay-Sayan mountain area. Meanwhile, marks of the land ice-sheet glaciation ought to be expected in the central parts of the plain. However, no marks of the stages of this glaciation have been found in Sartan time layers in Ob river areas of Surgut region (Arkhipov et al., 1980; Laukhin et al., 20
