Altyn-Tagh, (Astyn-Tagh, Altun Mountains, Pinyin: Altun Shan, A-erh-chin, Wade–Giles:A-erh-chin shan, Aerjin Shan, (Chinese: 阿尔金山)) is a part of the range south of Lop Nor), and is a mountain range in northwestern China that separates the eastern Tarim Basin from the Tibetan Plateau. The western third is in Xinjiang while the eastern part forms the border between Qinghai to the south and Xinjiang and Gansu to the north.

Altun Shan is also the name of a 5,830 metres (19,130 ft) mountain near the eastern end of the range.

Etymology

Altyn Tag means Gold Mountain in Turkic, and Shan is Chinese for mountain.

Geography

A series of mountain ranges run along the northern edge of the Tibetan Plateau. In the west are the Kunlun Mountains. About half way across the Tarim basin, where the mountains begin to orient somewhat to the north, the border range becomes the Altyn-Tagh, while the Kunluns continue directly east, forming a "V". Inside the "V" are a number of endorheic basins. The eastern end of the Altyn-Shan is near the Dangjin Pass on the Dunhuang-Golmud road in far western Gansu. East of the Altyn-Tagh the border range rises to the Qilian Mountains. The range separates the Tarim Basin, to the north, and Lake Ayakkum, to the south. The range can be divided into three portions. The southwest portion borders the Kunlun Mountains, is very rugged, with peaks reaching more than 6,100 metres (20,000 ft) and many perrenial snow fields. The central portion is lower in elevation, around 4,000 metres (13,000 ft), and the eastern portion. The eastern portion is higher in elevation, about 5,000 metres (16,000 ft) and consists of a group of smaller ranges oriented in a south-east to north-west trend.

Along the northern side of the mountains ran the main Silk road trade route from China proper to the Tarim Basin and westward. The Altun-Tagh and Qilians were sometimes called the Nan Shan ('south mountains') because they were south of the main route. Near the west end of the Altun-Shan the Gansu or Hexi corridor ends and the silk road splits. One branch follows the Altun-Tagh along the south side of the Tarim Basin while the other follows the north side.

The southwestern part of the Altyn-Tagh range reaches snowy peaks of up to 6,295 metres (20,653 ft), although it descends to an average of 4,000 metres (13,000 ft) in the narrow middle and eventually rises up to average 5,000 metres (16,000 ft) as it meets the Nan Shan.

There are a dearth of rivers and streams in these mountains, due to the aridity of the region. The western portion has some small streams that either head north into the dessert or south into Lake Ayakkum. The remainder of the range is lacking in rivers.

Intermontane endorheic basins

Inside the "V" shaped area between the Altyn-Tagh and the main Kunlun range (which in this area is called Arka-Tagh) a number of endorheic basins are located.

Within southeastern Xinjiang, the main of these basins is the Kumkol Basin (Chinese: 库木库里盆地; pinyin: Kùmùkùlǐ Péndì)

The two main lakes in this basin are the saline Lake Aqqikkol (also Ajig Kum Kul, Achak-kum; Chinese: 阿其克库勒湖; pinyin: Āqíkèkùlè Hú; 37°05′N，88°25′E, 4,250 metres (13,940 ft) elevation) and Lake Ayakkum (Chinese: 阿牙克库木湖; pinyin: Āyákèkùmù hú; 37°30′N，89°30′E; elevation 3,876 metres (12,717 ft)). These lakes are two of the few noticeable bodies of water in this extremely arid area; the area around them is officially protected as the Altun Shan Nature Reserve.

Farther east, in northwestern Qinghai, the much larger Qaidam Basin starts between the Altyn-Tagh and the Kunlun and extends almost to the east side of the plateau; the Altyn-Tagh separates the west side of this basin from the Kumtagh Desert.

Major Peaks

The six highest peaks are Ak Tag (6748 m), Sulamutag Feng (6245 m), Yusupu Aleketag Shan (6065 m), Altun Shan (5830 m), Muzluktag (5766 m) and Kogantag (4800 m).

Economic development

China National Highway 315 crosses the Altyn-Tagh on its way between Qinghai and Xinjiang.

As of the late 2013, preliminary planning is conducted for the Kurla-Golmud Railway, which, if constructed, will cross the Altyn-Tagh as well.
