Iron meteorite from Argentina, Campo del Cielo

An iron meteorite from Argentina, Campo del Cielo. An etched cut surface shows the characteristic Widmanstätten pattern, which is only found in iron meteorites.

Iron meteorites consist of an iron-nickel alloy (typically 90% Fe, 5-15% Ni with traces of cobalt, phosphorus, and sulfur). They originate from the core of shattered asteroids and are the oldest solid materials in the solar system, approximately 4.5 billion years old.

The Campo del Cielo strewn field in Argentina documents one of the largest meteorite impacts in recent Earth history, approximately 4000 years ago. The deposit is classified as a premium provenance in the collector's market.

The geometric pattern of kamacite and taenite lamellae only forms during very slow cooling over millions of years. It proves the cosmic origin of the material and cannot be artificially created on Earth.
