According to a Phys.org report, Haichao Li of Sichuan University led a team of researchers in the analysis of fragments of iron discovered in southwestern China at the Sanxingdui site, a city occupied between 2800 and 600 B.C. So far, eight sacrificial pits containing metal objects such as bronze masks, trees, and figurines have been excavated at the site. The three iron fragments, which appear to have been parts of an ax-like weapon, were discovered in Pit 7. Because this object was found in the sacrificial area, the researchers suggest that it had ritual significance. Metallographic and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) analysis of the metal confirmed that the weapon had been made of iron before iron smelting was widely practiced in China. The researchers also noted that the chemical homogeneity of the iron used to make the weapon would have been difficult to achieve with the technology available at the time, suggesting that the iron's source was a meteorite. "While the SEM-EDS results provide preliminary insights, they are insufficient to definitively classify the specific type of meteorite…the precise classification, therefore, remains unresolved," explained Zishu Yang of Sichuan University. The team members plan to refine their study of the metal and compare it with known meteor falls in the region. For more on Sanxingdui, go to "The Many Faces of the Kingdom of Shu."

Where did the Chinese get their tin?

From the Khmer?

The masks are some nice metal work . A decent rooster too. Might be from a local chicken joint. Eat at Joe’s

Afghanistan. Lapis lazuli continues to be mined there, but shows up in Neolithic archaeological contexts.

Thew source article at phys.org calls it “nickel-iron” and leans heavily on the meteorite connection.

Probably can be ruled in or out based on isotopes or ratios.

Well surprise surprise🤡

Odd that they didn’t invent waffles.
