Dongtai jinaer Lake

The jinaer Lake area of Dongtai, located in the hinterland of Qaidam Basin, is a large-scale lithium deposit dominated by brine.

The color of the lake is different from that of Qinghai Lake. Due to the high copper content, the lake water is bright green, and the shore is covered with white crystals.

The lake is surrounded by a large area of Yadan landform, with bright green water, just like the "Sea fleet".

The road passes through the middle of the lake. Due to the high salt content, it is better not to touch it with hands.

Dongtai jinaer Lake

In the Qaidam Basin of Golmud City, the periphery of the lake basin is the Quaternary proluvial, alluvial, aeolian and lacustrine clay and chemical deposits; the lakeside is mostly lacustrine and lacustrine chemical deposits, and the saline alkali land is widely distributed; in the East is nearly 50.0 square kilometers of sandy dry salt beach, with a thickness of 15.0 ~ 20.0 m, and the bottom salt deposit is 2.0 ~ 3.0 M. The water level is 2681.00m, the length is 24.0km, the maximum width is 8.7km, the average width is 5.05km, and the area is 121.3km2.

ecological environment

The lake area belongs to Chaidamu desert arid and extremely arid climate, with an average annual temperature of 2.0 ℃ and an annual precipitation of less than 25 mm. The catchment area is 38500.0 square kilometers, and the recharge coefficient is 156.0 (including the xitainaer Lake). The lake water is mainly supplied by jinaer River in Dongtai. The upper source of jinaer River in Dongtai is nalengele River and Hongshui River, which originate from hetuobanri snow mountain and bukadaban snow mountain in Kunlun mountain. The annual average flow of nalengele river is 33.83 m3 / s, with runoff of 1.035 billion m3, of which the runoff of glacier melt is 307 million m3 (Yang zhenniang, 1991). According to the investigation in June 1980, the lake has a density of 1.210, pH value of 7.75, salinity of 331.53g/l, cation Na +, K +, Mg2 + and Ca2 + contents of 116 452, 3 786, 5 686 and 433.7mg/l, anion Cl -, SO42 - and HCO3 - contents of 187037, 18 028 and 111.8mg/l, belonging to magnesium sulfate subtype Salt Lake, and Li, B and HCO3 - contents of 141 and 214.5mg/l, respectively. The solid salt deposits are dominated by halite with huge reserves; the upper layer is a new salt layer at the bottom of the lake, and the lower layer is muddy sandy halite. Li in brine and intercrystalline brine is a liquid deposit with comprehensive development and utilization value
