The North-South exposure width of the red stratum is more than 160 kilometers, and the east-west extension length is nearly 600 kilometers. The large exposed area of red strata is rare in China. The brick red and purplish red rocks of Tanggula Mountain in this "red mountain range" were weathered and denuded, and then transported by the river to Hoh Xil basin for deposition. Later, they were exposed to the ground after being transformed by geological tectonic movement, forming the current landform. (Xinhua News Agency) according to Xinhua news agency, Hoh Xil, located on the Qinghai Tibet Plateau, is the largest no man's land in China. During the ongoing scientific research activities on the source of the Yangtze River at China University of Geosciences (Wuhan), the scientific research team found a local rare large-scale "red mountain range" in Hoh Xil. The discovery of this special geological phenomenon will help to deepen the scientific research on the uplift process of the Qinghai Tibet Plateau. According to shentianyi, a member of the scientific research team and an associate professor of the school of Geosciences of China University of Geosciences (Wuhan), these "red mountains" in the Hoh Xil basin were mainly formed in the late Cretaceous to Paleogene between 70 million and 30 million years ago. The mountain range is nearly east-west, with asymmetric slopes, steep in the South and gentle in the north. The stratigraphic section is exposed clearly. It is a spectacular paleogeological relic on the Qinghai Tibet Plateau. Geological research found that Hoh Xil was a large lake with a low altitude more than 30 million years ago. Later, with the uplift of the Qinghai Tibet Plateau, Hoh Xil was uplifted to form an Intermountain basin. According to the scientific research team, the geological landscape of "red mountains" in Hoh Xil is expected to become a large "Geological Park" in Hoh Xil, which contains rich geological information closely related to the uplift process of the Qinghai Tibet Plateau.
