Tuanjie Lake at the southern edge of the Qaidam subbasin[1] in the eastern Qarhan Playa at an elevation of 2,675 m (8,776 ft) above sea level.[2] It has an area of 6 km2 (2.3 sq mi).[2] It lies southeast of Dabusun Lake, south of Xiezuo Lake, and west of South Hulsan Lake[1] and is fed by the intermittent stream of the Shougong River (收工河, Shōugōng Hé).[3] Its depth usually does not exceed 1 m (3 ft 3 in).[4]
Tuanjie's position at the south end of the playa means that its waters are relatively less influenced by the concentrated mineral springs along the playa's northern boundary.[5] Nonetheless, the lake's brine is at or near saturation with calcite, halite, polyhalite, kieserite, and (importantly) carnallite,[6] which is processed to produce potash for potassium-rich fertilizers and other uses.
