The Tarim Basin is the most western part of China and is located in the Xinjiang region. It is around in size 906 500 km2 and is dominated by the Taklamakan Desert. It includes the Turpan Depression which is one of the lowest places on Earth. Ayding Lake, within the Turpan Depression is at -154.5m below sea-level.
The Tarim Basin is thought to be a potential source for the loess in the Chinese Loess Plateau based on bulk sediment Nd and Sr data from Lui et al. 1994.
