==Structure== Octahedrites derive their name from the crystal structure paralleling an octahedron. Opposite faces are parallel so, although an octahedron has 8 faces, there are only 4 sets of kamacite plates. Due to a long cooling time in the interior of the parent asteroids, these alloys have crystallized into intermixed millimeter-sized bands (f...

The commonest type of iron meteorite. Octahedrites are composed mainly of the nickel-iron minerals taenite and kamacite and are named for the octahedral (eight-sided) shape of the kamacite crystals. When sliced, etched with a weak acid, and polished, octahedrites show a characteristic Widmanstätten ...
