Abstract: Kalas lakc is luculcd at Kalas river valley of Altay Mountains. It is a morine lake and formed after last glaciation. The characteristics of the deposit at the lake bank, such as spore pollen, grain size and clastic mine-rals and so on, are shown that there were three or four times climate fluctuations during the deposition at Ka1as Region. The characteristics of the deposition is different in various depositional environnlcnt.
