Iron-Nickel Meteorite with Distinctive Regmaglypts Extraterrestrial Fragment - Mesosiderite - Height: 60 mm - Width: 47 mm- 163 g - (1)

A cosmic fragment from the remote Chaco region, witness to a prehistoric impact — This specimen represents an authentic fragment of the famous Campo del Cielo meteorite, classified as IAB-MG (Iron, Group IAB, Main Group), a type of iron meteorite composed mainly of iron-nickel alloys, with smaller percentages of elements such as cobalt, phosphorus, sulfur, and carbon. Its metallic composition crystallized in an octahedrite structure is the result of slow cooling inside a parent asteroid body. Visual analysis reveals an intensely sculpted external surface, characterized by deep and distinctive regmaglypts. These marks, reminiscent of fingerprints, are the result of selective ablation of rocky and metallic material during the scorching passage through Earth’s atmosphere. The surface patina, gray-silvery in color with slight brownish tints due to post-fall surface oxidation processes, preserves traces of the original fusion crust. The meteorite’s provenance is the vast Campo del Cielo plain, located between the provinces of Chaco and Santiago del Estero in Argentina. This site is famous for hosting one of the most significant meteorite impacts in recent Earth history, which occurred about 4,000–5,000 years ago. The area is dotted with impact craters and thousands of tons of meteoritic fragments, making it one of the world’s most prolific sources of iron meteorite specimens. Aesthetically, the specimen stands out for its irregular yet harmonious shape and the richness of surface details, which offer clear testimony to the extreme forces endured during its space journey and atmospheric entry. The mass of the piece allows for a solid grip, enabling appreciation of its density and tactility, characteristic of iron meteorites. The preservation state is excellent, with no signs of improper handling or surface treatments that would alter its authenticity. The piece is in its natural condition, exactly as retrieved, with all morphological peculiarities generated by cosmic and atmospheric events intact. It requires no additional supports and can be displayed directly on a flat base. For the collector, this meteorite represents not only a tangible piece of cosmic history but also a high-value educational specimen with scientific significance. Its well-documented provenance and its morphological characteristics make it a reference point for the study of IAB-MG iron meteorites, offering a direct comparison with other Campo del Cielo specimens and with meteorites of different origins. It is an opportunity to own a fragment from another world.
