Jilantai Salt Lake

Jilantai Salt Lake

Jilantai Salt Lake is one of the large inland salt lakes in China. It used to be called Tang Wenchi, Dabusu, jilantanur, Taoli Nur and so on. As early as 1783, the name of jilantanur was used and has been used all the time. Jilantai Salt Lake is located in Alashan Left Banner, the southwest edge of Ulanbuh Desert in Inner Mongolia. It is located on the alluvial proluvial fan between Helan Mountain and Bayan Wula mountain on the southwest edge of Ulanbuh Desert. Its geographical coordinates are 105 ° 42 'e and 39 ° 45' n. It is a NE-SW trending elliptical basin. Surrounded by Gobi grassland and sand dunes.

brief introduction

Jilantai Salt Lake covers an area of 120 square kilometers. The eastern and western parts of the lake basin are on the high side. They are the low mountains and hills of Helan Mountain and Bayinwula mountain respectively, surrounded by Ulanbuh Desert and Tengger Desert. The basin is 200 km long, 30-40 km wide and covers an area of 2000 km2. Jilantai Salt Lake is located in the Northeast low-lying part of the basin. Due to the continuous precipitation and accumulation of salt, it has formed a series of salt dams.

mineral resources

The salt lake covers an area of 120km2, of which the salt mine covers an area of 37.19km2, with exploration reserves of 114 million tons. There are potassium, magnesium and other rare and precious chemical elements, which have high industrial exploitation value. Lake salt is famous for its large particles, strong taste, crystal clear and less impurities. It produces more than 600000 tons of high-quality lake salt every year and is an important salt mine production base in Inner Mongolia. Six of the eight salt mines in Inner Mongolia, which are listed in the national plan, have been damaged by quicksand to varying degrees, and Jilantai Salt Lake is one of the more serious ones. In the past 20 years, the environment of Jilantai Salt Lake has been degraded and the sandstorm disaster has become more and more serious.

In the early 1960s, there was 0.1-0.2m surface brine on the surface of Jilantai Salt Lake, which has evolved into a dry salt lake development stage without surface brine. The buried depth of intercrystalline brine is 0.3-1.0m, the salinity is 286.51g/l, the relative density is 1.2017, the pH value is 6.71, and the hydrochemical type is sulfate magnesium sulfate subtype.

Jilantai Salt Lake is rich in rock salt and mirabilite resources, mainly rock salt. The salt forming area of halite is 60km2, the sedimentary thickness is 3-4m, the maximum thickness is 5.9m, and the reserve is more than 97 million tons; the mirabilite sedimentary thickness is 1m, and the reserve is about 9 million tons. Jilantai Salt Lake is the largest salt lake deposit in western Inner Mongolia.

In Jilantai Salt Lake, salt was collected and eaten as early as 200 B.C. in the pre Qin period, with a history of 2000 years, but the large-scale production was still after the founding of the people's Republic of China. The lake area has built a special railway line, and its production technology has been continuously improved and updated. It has realized mechanized salt mining, processing and transportation, and developed a series of natural carotene, metal sodium and other salt products. It is the largest rock salt production base in Inner Mongolia Autonomous Region.

Historical and cultural value

Jilantai Salt Lake is also a treasure house of dinosaur fossils in China, which is the yearning place of paleontologists at home and abroad.
