WebThe Elga meteorite is a fine-grained octahedrite with numerous (up to 15 vol.%) rounded silicate inclusions (up to a few millimeters in size) . The texture and composition of the metal and silicate inclusions indicate that the meteorite shows traces of secondary melting caused by shock metamorphism [1,5,8,9,10,11,12,13,14,15,16,17,18,19,20]. WebFrom a massive fall with numerous specimens, this meteorite end cut exhibits the small fine octahedrite crystal pattern of the Widmanstatten lines, which was caused by the slow cooling of the large planetary mass …

The structures occur because the meteoric iron has a certain nickel concentration that leads to the exsolution of kamacite out of taenite while cooling. See more 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.
