Glacial Landforms East of Mount Meylixueshan in Yunnan Province, China, and its Implication to the Mountain Uplift during the Late Pleistocene and Holocene

Glacial landforms in the valleys of the Shenchenbao Glacier and the Lailogoru Glacier located on the eastern side of Mt. Meylixueshan (6,740 m), the highest mountain in Yunnan Province, China, were investigated in the field. The Shenchenbao Glacier terminates currently at 3,570 m and in the valley below, four terminal moraines and one pair of grand lateral moraines are recognized. The lowest terminal moraine is located at 3,260 m, about 2.5 km down from the present glacier snout. The snout of the Lilogoru Glacier lies at 2,650 m, about 900 m lower than the Shenchenbao Glacier. Located in front of the Lilogoru Glacier are two sets of terminal and lateral moraines. The elevation of the lowest terminal moraine is 2,360 m, about 2 km from the present glacier snout. The lowest lateral moraines are indurated and consolidated enough to stand as nearly vertical walls.
