Zabuye Chaka

Zabuyechaka, also known as zabuyechuo, chamucuo and zabuyechuo, is located in renduo Township, longer District, Zhongba County, Xigaze Prefecture, Tibet Autonomous Region. Its geographical coordinates are 83 ° 57 ′ 10 ″ - 84 ° 15 ′ 08 ″ e, 31 ° 27 ′ 10 ″ - 31 ° 34 ′ 30 ″ n. The lake area is a cold and semi-arid climate area on the plateau. The annual average temperature is 1 ℃, the annual temperature difference and daily temperature difference are large. The annual precipitation is 192.6 mm, the annual evaporation is 2269.1 mm, the wind is frequent, the annual gale days are 172 days, the annual average wind speed is 5.8 M / s, and the annual sunshine hours are 3300 hours. The lake basin is a closed inner flow basin, which is recharged by river water, atmospheric precipitation and groundwater. It is one of the three largest lithium salt lakes in the world.

essential information

Zabuyechaka lake is divided into South Lake and North Lake. Nanhu Lake is a solid-liquid lake with an area of 243 square kilometers, a water depth of 2M and an elevation of 4429

m. The North Lake is a brine lake with an area of about 100 square kilometers and a depth of several meters.

Salt lake resources

Zabuyechakahu lake is rich in resources with complete types, including brine resources, salt sedimentary resources and biological resources. Brine resources

The brine resources are divided into lake surface brine and intercrystalline brine. The lake surface brine is mainly North Lake, and the intercrystalline brine is mainly South Lake. The results show that the salinity of the intercrystalline brine is 439.8g/l, pH 9.31; the salinity of the surface brine of Beihu lake is 393.5g/l, pH 9.15; the salinity of the surface brine of Nanhu Lake is 369.0g/l, pH 9.17. The chemical type of brine is carbonate type, and the contents of K, B, Li, Rb, CS, Nb, Gd, th and as are outstanding, which has important comprehensive utilization value.

Solid salt resources

Solid salt resources include halite, mirabilite, borate and hydromagnesite. Among them, rock salt is the main salt resource, about 40 million tons, distributed in zabuyechakanan Lake; mirabilite and borate are sandwiched in the rock salt sedimentary layer in layers; hydromagnesite resources include hydromagnesite and magnesite, distributed in the spring belt around the lake and Quanhua island in the lake, with wide distribution and abundant reserves.

Zabuyechaka is a salt lake rich in lithium, one of the three largest lithium salt lakes in the world. Its taste of lithium ranks second in the world and first in China. At the same time, the content of cesium is also in the forefront of the world.

Biological resources

Biological resources refer to Artemia resources, which have important development value.

Metallogenic causes

Academician Zheng mianping used "multi-stage salt lake salt forming model" to explain the formation of zabuyechakali. More than 2 million years ago, zabuyechaka belonged to an ancient lake basin called longer. At that time, the lake water was widely distributed and the lake surface was more than 100 meters high. Later, the climate became dry and the lake water began to shrink. Longer basin disintegrated and formed many secondary lake basins from high to low. Zabuyechaka was located in the lowest secondary Lake Basin, and the higher lake basins around it were arranged in a ring pattern, connected with zabuyechaka through multiple Lake chains. In the process of supplying surface or underground brine to zabuyechakar through these Lake chains, some salt components are dissolved along the way, which makes the brine rich. In this way, under the supply of high salt lakes, zabuyechakar has the longest salt forming time, the most soluble salt and the largest scale, forming a comprehensive deposit of boron, lithium, potassium and other salts in Tibet.

Another expert put forward the metallogenic theory of the ancient great lake.
