青藏公路横穿青藏高原,我们在沿线进行地貌和第四纪地质的考察,研究了昆仑山、唐古拉山和念青唐古拉山的第四纪冰川。现就有关第四纪冰期划分的研究成果,择要报道如下: 一、冰期和间冰期系列 考察中所见的第四纪冰川遗迹,多集中于山区和山麓地区。通过各类冰川遗迹的追索和鉴定,确定了不同的冰碛层及各自的层位,并综合考虑地貌、构造、沉积物及风化程度等特征, Qinghai-Tibet Highway crosses the Qinghai-Tibet Plateau. We conducted geomorphological and quaternary geological surveys along the route to study the Quaternary glaciers of the Kunlun Mountains, the Tanggula Mountains and the Nyainqentanglha Mountains. Now on the division of the Quaternary ice research results, the choice to be reported as follows: First, the glacial and interglacial series of expeditions seen in Quaternary glacial relics, and more concentrated in the mountains and foothills. Through the recourse and identification of various types of glacial relics, different moraine layers and their respective horizons have been identified. Considering the characteristics of landform, structure, sediment and weathering degree,
