The Turpan Depression or Turfan Depression, is a
By some measures, it is also the hottest and driest area in China during the summer.[2]Geology and relief
The Turpan Basin is a fault-bounded trough located in the eastern part of the Tian Shan. It covers an area of 50,000 square kilometres (19,000 sq mi). The surrounding mountain ranges are: the central Tian Shan in the west, the Bogda Shan in the north-west, the Haerlike Shan in the north-west, and the Jueluotage Shan in the south. Beyond the surrounding mountain ranges lie the Junggar Basin in the north and the Tarim Basin in the south.
Some geographers also use the term Turpan-Hami Basin, which is understood as including the Turpan Depression along with the
The Turpan Basin formed in a
Also in the center of the basin lies the Ayding Lake (Moonlight Lake) which has an elevation of 154.5 m (507 ft) below sea level, the sixth lowest exposed elevation on the Earth's land surface. It is the lowest surface point in China.
The Shihongtan uranium ore deposit is located at the southwestern margin of the Turpan Depression, some 35 km (22 mi) south-southwest from Turpan City.[3]

Climate
The Turpan Basin has a harsh, continental desert climate (Koppen BWk) in which the precipitation is far less than the potential evaporation. At Turpan City, July is the hottest month with a 24-hour average temperature of 32.2 °C (90.0 °F) and January the coldest with a 24-hour average temperature of −7.6 °C (18.3 °F). Monthly rainfall is highest in June, at 2.9 millimetres (0.11 in) and lowest in February and April, at 0.5 mm (0.020 in). The annual average precipitation is only 15.7 mm (0.62 in), falling on only 13 days per year. In contrast to this, the potential annual evaporation rate reaches 3,000 mm (120 in).[citation needed] Because of its climate, the area is sometimes counted as one of the Furnaces of China, although the locations included under this heading vary.
