A third relic of the ancient cosmos is this iron meteorite, Mungindi. It represents the core of an old planet whose heavy matter, in this case iron-nickel alloy, separated from the lighter silicate shell and sank to the interior.
Mungindi is composed of the iron-nickel alloys kamacite and taenite. Intergrowths of these minerals make up the distinctive pattern, known as Widmanstätten structure. The nodular masses are composed of the iron sulfide mineral troilite.
