Muonionalusta meteorite

Muonionalusta was discovered in 1906 in Kiruna, Sweden, near the Arctic Circle. It is metallic and belongs to the class of octahedrite syderites. It is composed mainly of iron and nickel. It is recognisable by the fineness of its crystals and the geometric shape of its lamellae, a characteristic of iron meteorites. These structures (called Wiedmanstätten figures) are revealed whenever the steel is heated to high temperatures in acid. Genuine meteorite with a certificate of authenticity.
