Formation of China's Dead Sea & Its Causes

According to water quality tests conducted by the Sichuan Bureau of Geological Exploration and Development on underground natural brine mineral water in Daying County, the brine of China's Dead Sea is mainly composed of sodium chloride (table salt), and rich in over 40 minerals and trace elements including potassium, calcium, iodine and bromine.

Different from ordinary hot spring water, the brine contains various ionic salts such as magnesium salts, carbonates, sulfates, potassium salts, calcium salts, iron oxides, aluminum oxides, silicates and bromide salts. Modern medical research has proven that these substances can effectively improve and regulate human health, which accounts for the high healthcare value of this water body.

Around 150 million years ago, two major orogenic movements formed an ancient underground salt lake basin in Daying County. The basin holds abundant reserves of salt brine, with proven reserves reaching 4.2 billion tons.

The salinity of the water in China's Dead Sea exceeds 22%, dominated by chloride salts. Similar to the Dead Sea in the Middle East, the water density allows people to float effortlessly on the surface without sinking.
