Lanzhou (China), Apr 8(ANI): Chinese scientists have said that they have identified a landform left by glacial erosion at least two million years ago on mountains in Gansu Province of the country.
"The erosion, on the southeast edge of the Qinghai-Tibet Plateau and bordering the western provinces of Gansu and Sichuan, started two million to three million years ago and ended about 20,000 years ago," Xinhua news agency Shen Yongping, a researcher with the Cold and Arid Regions Environmental and Engineering Research Institute, as saying.
Shen and his colleagues from the Lanzhou-based institute are planning to complete the expedition before the end of this year.
Filmmakers from a cultural promotion company in Lanzhou had first discovered the landform, with an average altitude of 3,500 meters atop the Zhagana Mountains, in 2007.
Shen further said he visited the site last year and saw U-shaped valleys, steep ridges and enlarged hollows.
"These are typical landscape features formed by glacial erosion," he added. (ANI)
