Abstract: The systematic analysis of glacial remains reveals the snowline changes and glaciation process in Mt.Taibai of the Qinling Mountains, By comparing it with the climatic changes of late pleistocene in the Loess plateau, we expose that.35,000-10,500 year B.P., cirque-mountain valley glacier formed in Mt, Taibai, snow-line was on 3,400m,10,500-8,500 year B. P, snow-line was on 3,500m.glacier tongue retreated and changed into cirque glacier.8,50C-6,800 year B, P., snow-line rose above the top of Mt.Taibai,snow disappeared in the summer,6,800-5,000 year B, P.,snow-line lowered on 3,600m,parasitical cirque glacier formed,5,000-3,120 year B.P., sonw-line rose again above the top of Mt.Taibai, snow disappeared in summer,3,120-1,400 year B,P.,snow line lowered periglacial rockfield formed on the top of Mt,Taibai.Last 1,100 year, snow-line has risen to 4,500 m,no snow can be kept in summer on the top of Mt.Taibai.
