The peacock jade stand is a product of the late evolution of the columnar Yadan body. Due to the erosion of the surface of the Yadan body by wind and rain, the weak parts gradually disappear and the relatively hard parts are retained. They form a lifelike and lifelike “peacock”, which is standing proudly and showing its beauty to people. .
This Yadan landform in Dunhuang is already on the edge of Lop Nur, covering an area of ​​about 400 square kilometers. Its formation took about 700,000 to 300,000 years. When strong wind blows, it will make various strange sounds, so it is also called Dunhuang Yadan Devil City.
