Ordos Loop

The Ordos Plateau, also known as the Ordos Basin, the Ordos, or the Shaan-Gan-Ning Basin, is a highlandsedimentary basin in parts of northernmost China with an elevation of 1,000–1,600 m (3,300–5,200 ft), and consisting mostly of land enclosed by the "Ordos Loop", a northerly rectangular bend of the Yellow River. It is China's second largest sedimentary basin (after the Tarim Basin) with a total area of 370,000 km (140,000 sq mi). The Ordos includes territories from five provinces: Shaanxi, Gansu, Ningxia, Inner Mongolia, and a thin fringe of Shanxi (western border counties of Xinzhou, Lüliang and Linfen), but is demographically dominated by the former three, hence the area is sometimes also called the "Shaan-Gan-Ning Basin". The basin is bounded in the east by the Lüliang Mountains, north by the Yin Mountains, west by the Helan Mountains, and south by the Huanglong Mountains, Meridian Ridge and Liupan Mountains.
