在西藏阿里阿伊拉日居山脉南北两麓及切割山脉的各沟谷中,分布着4套早更新世以来的冰川沉积物。根据这些冰川沉积物的地层层序和冰川沉积物的电子自旋共振(ESR)年龄测定结果,将阿伊拉日居山脉南北两麓所发生的4次早更新世以来的冰川作用,分别命名为札达冰期(1161-952 ka BP)、阿伊拉日居冰期(762-730 ka BP)、学朗冰期(336-211 ka BP)和弄穷冰期(105-15 ka BP),并与青藏高原及其他地区冰期进行了对比。各次冰期的冰川性质分别为大型山岳冰川、冰帽、山麓冰川和中小型山谷冰川。全新世时期,现代冰川有过冰川推进。近期冰川则发生了明显的后退。
Four sets of glacial sediments have been distributed since the Early Pleistocene in the valleys north and south of the Aljirah Habitat Mountains in Tibet and the cutting mountains. Based on the stratigraphic sequence of these glacial sediments and the ESR dating of glacial sediments, the glaciations since the Early Pleistocene occurred at the two north and south halves of the Ailajedo Range were named (1161-952 ka BP), the Aira glacial period (762-730 ka BP), the Xuelang ice age (336-211 ka BP) and the poor ice age (105-15 ka BP) The Qinghai-Tibet Plateau and other regions during the ice age were compared. Glaciers in each glacial period are large mountain glaciers, ice cap, foothills and small and medium sized glaciers. During the Holocene, glaciers had been advanced in modern glaciers. Recent glaciers have taken a significant step backwards.
