| Final Disappearing Process of Ancient Lake during Quaternary in Nihewan Basin |
| Nihewan Basin located in the northwestern of Hebei Province and northeastern of Shanxi Province. The administrative division of Nihewan Basin belongs to Yangyuan County Zhangjiakou Hebei Province and Datong County - Tianzhen County Datong City Shanxi Province. The extent of the basin is west to Dongjingji rural area Yangyuan County, east to the Sanggan river valley-east of Shixia, north to Bear mountain, south to the Liuleng mountain and Phoenix mountain. Nihewan Basin is about 80 km long from east to west and 15 ~ 20 km wide from north to south, which generally located N39°55′–40°25′ and E113°50′–114°50′, with an area of 4 500 km2. The scope of Nihewan Basin was roughly the same scope of Yangyuan Basin. Pluvial fan and diluvial plain were developed along the basin edge and lacustrine and alluvial plain covered the central part of the basin. The Sanggan River flowed through the basin from southwest to northeast. |
