Ancient Chinese site yields oldest iron meteorite object
Summary and headline written by AI from the source article. How we work
Archaeologists in China’s Sichuan province discovered a rare iron meteorite object at the Sanxingdui archaeological site, dating back to the late Shang Dynasty.
The artifact, designated K7QW-TIE-1, measures over 20 centimeters long and contains over 90 percent iron with 7.41 percent nickel, a composition suggesting it originated from space. This discovery marks the largest iron meteorite found to date in China and the oldest of its kind in the country’s southwest region.
The Sanxingdui site, near Chengdu, has already challenged existing understandings of the Chinese Bronze Age with finds like ritual trees and bronze masks. The K7QW-TIE-1 object came from a ceremonial pit and was so fragile that archaeologists transported it to a museum with the surrounding soil for careful cleaning and analysis. Researchers determined the object’s composition through X-ray fluorescence and electron microscopy, finding a uniform distribution of nickel not achievable with the metalworking technologies of the time.
Unlike other Chinese meteoritic iron objects which often combine iron with bronze, this piece is made of a single metal and may have been directly shaped from the original meteorite block. Experts suggest it could have been a tool used to work the region’s famous bronze masks, or a ritual object given its location in a sacrificial pit.
The find expands knowledge of ancient Chinese metallurgy, previously centered on the country’s central plains, and joins a small group of similar discoveries like those found in Spain. Researchers plan further analysis to pinpoint the meteorite’s origin and connect it to known fall events, while prioritizing the object’s fragile preservation.
