在第四纪(55—65万年)期间,冰川在地球上分布很广,直到现在在高山区仍有广泛的冰川活动,我国的小唐古拉山就是一个现代冰川的实际例子。小唐古拉山是一个东西延长拔海约6000公尺左右的山脉,北以霍霍希里盆地与崑崙山脉相隔,南与大唐古拉山毗连,构成青、藏的天然分界。最高山峯高达6800余公尺,是常年积雪的地区,因此冰在强大的压力下变成可塑性的冰而沿着山谷缓慢的流动,以致形成了冰川。在小唐古拉山的加巷、吴曼通洞,其苏美一带,
Glaciers were widely distributed on Earth during the Quaternary Period (556,000 years). Until now there are still extensive glacier activities in high mountain areas. Our country’s small Tanggula Mountain is a practical example of a modern glacier. The small Tanggula Mountain is an extension of the sea about 6,000 meters above sea level pull the mountains to the north Hoh Xili basin and the Kunlun Mountains separated by the South and Datang Gula Mountain adjoining constitute the natural boundaries of green and Tibetan. The highest peak, which is as high as 6,800 meters, is a snow-covered area all year long, so that the ice is transformed into plastic ice under strong pressure and slowly flows along the valley, resulting in the formation of glaciers. In the small Tang Gula Mount Canadian Lane, Wu Man-hole, the Soviet Union and the United States,
