The Domeyko meteorite is an IIIAB iron meteorite, discovered in 2000 in northern Chile, specifically in the Atacama Desert near the famous Imilac pallasite fall. It was discovered by French collector and meteorite expert Luc Labenne during an expedition to an area rich in ancient meteorites. The site is located over 3000 meters above sea level in the Domeyko region, near the city of Antofagasta, from which the meteorite takes its name. Classification and Composition Domeyko is classified as a fine octahedrite belonging to the IIIAB group. These meteorites are characterized by the presence of nickel-iron in the form of the metallic phases Kamacite and Taenite, which, during extremely slow cooling in space, arrange themselves into a regular structure known as Widmanstätten patterns. These structures, visible after acid etching of a polished section, represent one of the main identifying elements of many iron meteorites. A particularly interesting element in the sections of the Domeyko meteorite are the so-called Brezina lamellae, very thin elongated inclusions rich in iron phosphide called Schreibersite. These lamellae form during the extremely slow cooling of the metallic material within the planetesimal body from which the meteorite originates. They are named after the Austrian mineralogist Arthur Brezina, who significantly contributed to meteorite research in the 19th century. Their presence indicates that Domeyko comes from a differentiated metallic core of a planetary body and has undergone an extremely slow cooling process, on the order of a few degrees per million years. Appearance and Conservation The original piece of the meteorite weighed approximately 13.88 kg and measured approximately 27 × 19 × 10 cm. Its surface is typical of meteorites found in the arid environment of Atacama, with surface cavities formed by corrosion and erosion in desert conditions. The lower part was rather smooth, while the upper part was covered with numerous small depressions and protuberances. The Domeyko meteorite is often considered one of the most aesthetically spectacular iron meteorites ever found, not only for its refined structural pattern, but also due to the presence of Brezina lamellae.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028627755333,"sku":"MEDO33","price":140.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/68896-2_photoroom-20260204-102328.jpg?v=1779383775","url":"https:\/\/moldavite.it\/en\/products\/meteorite-domeyko-25g-chile-medo33","provider":"Moldavite.it","version":"1.0","type":"link"}
