The Amazing World of Fusion Crust
      #2616692 - 09/01/08 11:26 AM Attachment (77 downloads)

Hi All,

Fusion crust has taken on a renewed importance in the authentication of specimens. But beyond its utilitarian use, it is really a sheen of solidified lava that reflects both the turmoil of the meteorite’s arrival on earth, but also expresses the individual chemical makeup of the space rock when melted.

From foamy jet-black, to tar-like shiny plastic, to milky brown paint, fusion crust is a characteristic of meteorites whose value only appreciates, and beauty only grows as one delves deeper into meteorite collecting. Here are a dozen examples of crust from my collection. Each is a testament to the extraordinary and individual nature of these beasts.

Enjoy.

Goalpara, India
Ureilite
Discovered in 1868 among the mineral and gem specimens provided to the Calcutta Museum by the Rajah of Goalpara.

It is presumed that the Goalpara meteorite was witnessed to fall which is how it wound up in a gem collection. It is not assumed that the Rajah of Goalpara knew that this class of meteorite called Ureilite actually contains diamonds, which it does.

Awesome Images,Martin. Those are some of the best looking specimens I have ever seen.

It is interesting comparing the differences in the fusion crust from each individual type of Meteorite. Though I would be more the happy to give any of the pictured specimens a place to call home.

But the sheer pressure,heat,and speed that each meteorite is subjected to during its descent is incredible.Its amazing with them experiencing these processes, that any would or could survive.

While going through a few pieces to place for sale at my store, I ran across this little piece with some of its Fusion Crust still in place.
This is a Specimen of NWA 869:
