Can the sand make a dog call and thunder?Scientists discover Mingsha on the coast of our country

Science Fiction Network June 20 (Qin Yingying) According to Xinhua News Agency, the latest research results show that there are also sands that can "sing" in my country. This is another new discovery of the Dunhuang Gobi Desert Research Station of the Dunhuang Gobi Desert Research Station of the Northwest Ecological and Environmental Resources Research of the Chinese Academy of Sciences.

Mingsha is the sand that can speak. The phenomenon of Mingsha is common, on the long island, Massachusetts Bay, West Coast of Wells in the United States, Bon Hedg Island in Denmark, Corburg in Poland, and some beaches and deserts in Brazil, Chile and Asia, and the Middle East. Sound.

This natural phenomenon of Mingsha is not only widely distributed in the world, but also a variety of sounds from sand. For example, the sand on Gao Ayi Island on the Hawaiian Islands in the United States will make a sound like a dog screaming, so people call it "dog barking sand." The sand on the Island of Scotland can make a magnificent sound. Rolling down from the Mingsha Mountain in China, the sand will be "a loud noise of a bombardment, like a thunder" as Zhu Kezhen described.

my country is a country that is recorded earlier in Mingsha. It is mainly known for the four major Mingsha land such as Mingshashan Mountain in Dunhuang. It is considered a magical natural phenomenon and has therefore become an important tourism resource. The researchers inspected the coast of Hainan Island, and found coastal Sands in the Shenzhou Peninsula, Qingshui Bay and other places, and compared and studied the newly discovered coastumi and the found inland desert Mingsha.

Researchers analyzed the similarities and differences between coastal Sands and inland desert Mingsha in mineral composition, particle size distribution, surface structure and acoustic signals. Studies have found that the content of Chinese quartz is significantly higher than the desert Mingsha, and the content of the long stone is significantly lower than the desert Sands; Essence At the same time, the "V" -shaped impact pits and chemical solubility of the coastal Sand on the surface with typical underwater mechanical etching effects. Important factor of sound mechanism.
