Researchers confirm 3,000-year-old Sanxingdui artifact as meteoritic iron

Chinese researchers have confirmed that iron fragments unearthed at the Sanxingdui Ruins were made of pure meteoritic iron. The three corroded pieces, found in Pit No. 7, likely formed an axe or ceremonial weapon. Carbon dating places the artifact in the late Shang Dynasty.

The Sanxingdui Ruins in southwest China's Sichuan Province are remnants of the ancient Shu Kingdom. The fragments expand the known range of meteoritic iron use from the Yellow River basin to the upper Yangtze River region.

A joint team from Sichuan University and the Sichuan Provincial Institute of Cultural Relics and Archaeology conducted the study. Their findings appeared recently in the journal Archaeological Research in Asia.

Meteoritic iron, a natural iron-nickel alloy from space, held ritual significance before smelting technology emerged. Researchers suggest the Shang Dynasty people viewed it as a gift from the sky and shaped it into a ceremonial object or ritual weapon.

The hardness of the material may also have allowed its use in processing bronze items found in the same sacrificial pits.

Archaeologists have uncovered evidence that early humans produced sophisticated stone tools in central China during a brutal ice age 146,000 years ago. The findings come from the Lingjing site and challenge previous assumptions about when human creativity emerged.

A lunar mineral named Changesite-(Ce) discovered by a Chinese research team has been approved by the International Mineralogical Association, marking the 11th globally identified lunar mineral. This brings China's total to four, equal to the United States. The mineral was found in the Pakepake 005 lunar meteorite, China's first recovered sample.

New research from Rutgers University reveals that meltwater from Antarctic ice shelves contributes far less iron to surrounding ocean waters than scientists had assumed. Instead, most iron originates from deep ocean water and continental sediments. The findings challenge expectations about iron fertilization and its role in carbon absorption.

China has completed a metal 3D printing test in orbit aboard its Qingzhou prototype spacecraft, the Chinese Academy of Sciences said Monday, marking progress in space-based manufacturing. Researchers remotely activated the system from the ground, with the payload meeting its objectives as planned. The technology is seen as key for future missions, enabling astronauts to produce and repair parts in space.
