Campo del Cielo - Meteorite – Iron-Nickel with Widmanstätten Structure - Height: 51 mm - Width: 30 mm- 58.2 g

The Campo del Cielo meteorite is an iron meteorite (class IAB-MG) discovered in Argentina's Chaco Province, in an area known for meteorite fragments estimated to have fallen between 4,000 and 5,000 years ago. The region is named "Campo del Cielo" (Spanish for "field of the sky") because of local legends that spoke of "fragments of the sky falling to Earth."
Iron (Fe): ~92%
Nickel (Ni): ~6-7%
Traces of cobalt (Co), phosphorus (P), gallium (Ga), germanium (Ge) and iridium (Ir)
Kamacite (low nickel iron-nickel alloy)
Taenite (high nickel iron-nickel alloy)
Troilite (iron sulfide)
Graphite and schreibersite (rare iron nickel phosphide)
The meteorite has a rough and irregular structure, typical of the fusion crust formed during its descent through the Earth's atmosphere. Some smooth sections may reveal the classic Widmanstätten structure, characteristic of iron meteorites, which consists of bands of iron-nickel alloy slowly crystallized in space over millions of years.
Cosmic age: ~4.5 billion years (formation)
Date of fall: Approximately 4,000-5,000 years ago
Isotopic analysis of the meteorite has provided insights into the formation of the solar system.
This Campo del Cielo specimen represents a fragment of the universe, a testimony to the birth of the solar system and the history of iron meteorites that traveled for millions of years before falling to Earth. Its rough, metallic appearance, combined with its internal Widmanstätten structure, makes it a fascinating piece for collectors and enthusiasts of mineralogy and astrophysics.
