Yuncheng "Sea of Death"
Origin and introduction
Yuncheng Salt Lake, located in Jinnan Basin, Shanxi Province, China, was formed in the fourth generation of Cenozoic era. Because the mountains go out to sea, a large number of salty minerals gather here, and after long-term precipitation and evaporation, a natural salt lake is formed. In feudal society, the salt tax of Yuncheng Salt Lake once accounted for one-eighth of the national fiscal revenue, which made great contributions to the survival and reproduction of the Chinese nation.
Yuncheng Salt Lake is comparable to the world-famous Dead Sea in Israel. The black mud in the lake contains seven kinds of constants and sixteen kinds of trace elements. People can row boats in the lake, and the black mud in the lake can beautify the skin, so Yuncheng Salt Lake is called the sea of death.
Yuncheng Salt Lake is the third largest inland lake of sodium sulfate type in the world, with an area of 65,438 0.32 square kilometers and a development history of more than 4,000 years. Salt Lake is bounded by Zhongtiaoshan in the south, Mingtiaogang in Emei in the north, Yaotai in Sushui in the east and the old capital of the Yellow River in the west. The lake is covered with silver, vast and boundless, surrounded by reed wetlands, and waterfowl gather.

65.438+0.5 billion years ago, the earth's orogeny made Sichuan a carbonate platform surrounded by the sea. Seawater flows at low tide for a long time, and a large amount of evaporated salt is deposited. The potential in Taiwan is relatively flat, and the paleogeographic landscape is shallow sea beach. Because Sichuan is far away from the seawater recharge site and has high water concentration, it is a platform salt-forming area. Since then, it has accepted the deposits of Upper Triassic, Jurassic and Cretaceous. With the increase of cover thickness and ground temperature, salt substances enter the stage of compaction diagenesis and thermal metamorphism. In this process, a large amount of dehydrated water is separated from salt substances and transported to adjacent reservoirs to form brine. It is understood that the salt-bearing area of the upper coal seam in Daying deep brine mine is 22,300 square kilometers, the salt layer thickness is 3.5- 15 1. 1 m, the lower coal seam area is 34,000 square kilometers, and the salt layer thickness is 2.5-196,5438+. Therefore, the ancient English salt lake is not only the source of the "sea of death", but also a huge resource treasure in Daying County.

Protect the sea of death;
From June 5438 to 10, 2003, Nanfeng Group, the source of China's well-known trademark Qiqiang, applied for trademarks such as Dead Sea, sea of death, sea of death, Far East Dead Sea and Sanjin Dead Sea in order to effectively protect China's resources-Yuncheng Salt Lake. In March, 2004, Nanfeng Chemical Industry Group Co., Ltd. went through strict examination procedures such as acceptance, preliminary examination, review and announcement by the Trademark Office of the State Council Administration for Industry and Commerce, and officially obtained the approval and registration certificates of service trademarks of Dead Sea, Far East Dead Sea, Sanjin Dead Sea and sea of death.
The Sea of Death is the first scenic spot to apply for patent protection.

The reporter learned yesterday that the Dead Sea Tourist Resort has just obtained five patent certificates issued by China National Intellectual Property Administration. The contents include patent applications for the preparation methods of the Dead Sea floating salt bath and lake salt health care floating liquid.
According to the relevant person in charge of the Dead Sea, since the opening of the scenic spot, some investors have been found to imitate the unique healthy floating of the Dead Sea under the banner of floating, so as to protect their good reputation and bring better exclusive rights to consumers. Therefore, Dead Sea recently applied for intellectual property protection for this patented technology.
At the same time, there are more than ten categories such as "Dead Sea Floating" and "Dead Sea Salt", with 68 registered trademarks. Protecting the sea of death, the invention of healthy tourism, from all aspects.
Only the sea of death-Shanxi Yuncheng is natural, and the sea of death-Great Britain was later developed and built by a company.
Xinhua News Agency-Magical "Sea of Death": Yuncheng Salt Lake
Outdoor saltwater floating bath in Yuncheng Salt Lake in winter (165438+1taken on October 6th). Yuncheng Salt Lake is located in Yuncheng City, Shanxi Province, with an area of 1.32 square kilometers. It was born during the Cenozoic Himalayan tectonic movement, and a large number of minerals were deposited on the lake when the mountains went out to sea. Yuncheng Salt Lake is strikingly similar to the "Dead Sea" in the Middle East. Lake water and black mud at the bottom of the lake contain more than 20 mineral elements such as potassium, calcium and sodium. Regular soaking is very beneficial to human health. At present, Yuncheng Salt Lake has been rationally developed in the local area, making it a tourist attraction featuring "saltwater floating" and "black mud bathing".
