Anonymous users2024-02-13The Hengduan Mountains are mainly ancient glacial erosion and accumulation landforms. There are many intermountain basins and lakes in the Hengduan Mountains, and ancient glacial erosion and accumulation landforms are widely distributed, and modern glaciation and gravity landforms such as landslides, landslides and debris flows are common. At the same time, it is one of the main belts in China, and the famous Xianshui River, Anning River and Xiaojiang are all distributed in this area.
The Hengduan Mountains are located on the axis of the Kang-Yunnan Axis between the trough area of western China and the platform area of eastern China. The Indochinese movement uplifted the folds into land and formed a series of fault basins. Jurassic and Cretaceous strata are deposited in the basin.
The Yanshan movement folded and fractured again. Until the middle of the Tertiary period, the earth's crust slowly rose and was leveled by long-term denudation, forming a vast flat. From the end of the Tertiary to the beginning of the Quaternary, the tectonic movement was extremely active, the unified plane deformed and disintegrated, and the height difference of the ridge valley tended to be obvious.
The Quaternary underwent several glaciations. The hilly plateau and the summit surface can be connected into a unified "base surface", with mountains on the "base surface" and river valleys and basins below. There is a huge difference in the height of the Hengduan Mountains and valleys. The ridge of Qionglai Mountain is more than 3,000 meters above sea level, the main peak Siguniang Mountain is 6,250 meters above sea level, and the relative height difference of its southeast slope is more than 5,000 meters.

The north column is Tianshan and Yin Mountain; It is listed as Kunlun Mountain-Qinling Mountains; The south column is the South Ridge.
2. The northeast-southwest trending mountain ranges are mostly distributed in eastern China, and there are mainly 3 columns (mainly including 7 mountain ranges): the west is listed as Daxing'an Mountains-Taihang Mountain-Wushan-Xuefeng Mountain; The middle column is Changbai Mountain-Wuyi Mountain; The eastern column is the Taiwan Mountains.
3. The northwest-southeast trending mountains are mainly distributed in western China, and there are two famous mountain ranges: the Altai Mountains and the Qilian Mountains.
4. There are two main north-south mountain ranges, which are distributed in the southwest and northwest, namely the Hengduan Mountains and the Helan Mountains.
5. The arc-shaped mountain system is composed of several parallel mountain ranges, which are connected with the Hengduan Mountains from the basic east-west direction to the north-south direction, among which the most famous mountain range is the Himalayas, which are distributed on the border between China and India, Nepal and other countries, stretching for more than 2,400 kilometers, with an average altitude of 6,000 meters, and its main peak, Mount Everest, with an altitude of meters, is the highest peak in the world.
