OctahedriteOctahedrites are a class of nickel iron meteorites. Typically composed of the alloys of nickel-iron: taenite - nickel-iron with high nickel content and kamacite - nickel-iron with low nickel content. A iron nickel phosphide, schreibersite, is present in some nickel-iron meteorites as well as an iron nickel cobalt carbide, cohenite. When polished and acid etched the classic Widmansttten lines, criss-cross pattern of intersecting lines of lamellar kamacite, are visible. Octahedrite is also an obsolete synonym for anatase, a titanium oxide mineral. References
