(3) The mystery of Shanxi meteorite

According to local records, Lingshi was dug out from the depths of the ground during the road construction in Sui Dynasty, and it was considered as an iron meteorite falling from the celestial body.

Lingshi, known as iron meteorite, has already spread all over China. In the 1950s, the Institute of Geochemistry of Chinese Academy of Sciences sent people to take samples for analysis, which was rejected because it did not contain Ni, Co and other elements peculiar to Tiantie meteorite. During 1975, Guiyang Institute of Geochemistry, Chinese Academy of Sciences sent people to Shanxi for isotopic age sampling. After seeing this "iron meteorite" through Lingshi, at the request of the entourage of the dispatching team in Shanxi, another piece was taken for testing. The result maintained the conclusion of 20 or 30 years ago, and it was not an iron meteorite. After two tests, the domestic authorities denied that this was a rumor. Therefore, when investigating geological relics in Shanxi, it was not included in the category of meteorites. However, it was later learned that this hard stone contains as much as 99% iron and is not refined by ancient techniques. Until today, all ironmaking methods can't reach such high purity, because carbon will definitely be mixed in the process of smelting and combustion, and the carbon content of 3% ~ 5% is definitely there. Now the purity of iron reaches 99%. If it's not from heaven, where did it come from? It is still a mystery.

This meteorite, which is regarded as a treasure by Lingshi County, does not show any melting trace and flow structure that a meteor should show when it enters the atmosphere, but only a large number of pore structures. There is no such phenomenon as high temperature and high pressure impact metamorphism around such a huge meteor hitting the surface.

There is no reasonable explanation for the existence of these contradictions.

2. Is the name of Lishi related to meteorites?

Lingshi meteorite is related to a huge lying cow iron on the floodplain of Daping village in the upper reaches of Loess Town in the east of Xixian County. Length 1.5m, width 1m and height 0.5 ~ 0.7m. The surface is smooth and rust-free, lying quietly in the gravel layer of the river beach. It is neither an iron ore producing area nor a coal producing area. It is surrounded by Paleozoic limestone, and no residues or fragments such as ironmaking slag and refractory bricks are found. At that time, there were doubts about its cause, and whether meteorites fell from the sky.

The dew point of Woniutie is located in the south of Lishi County. There is no origin of Lishi place names in the written introduction materials. As a county-level place name, it first appeared in the Qin Dynasty. At that time, Taoist gossip had entered many fields of society, especially for marking directions. Li Gua is due south fire Gua. Is it possible that some upper-class people saw a huge meteor falling in the south, so they named the witness Shi? With this in mind, I made a special trip there and found out its source through detailed field observation and sampling. Unexpectedly, this huge iron was smashed by villagers with explosives in the 1980s, and it was sold as waste at a price of 80 cents per catty. Unfortunately.
