This happened on many of the Tamdakht samples and when viewed on larger samples it is obviously not impact melt as the fusion crust can be followed around the specimen to the rear side of more oriented specimens where it then becomes frothy with embedded fragments from the main body...same matrix...I have several specimens of this not so common occurence.....wonderful example you have Greg. |

The piesec they found near Jonesboro from the Nov 5 2003 fall looked like that but Mike Farmer told them they weren't meteorites, so none have been recovered. Anyone think its time to go check again? |

Very nice piece with great details! |

I would vote impact melt is the frothy, glassy slag-like material. Sloughed off molten material from ablation can end up on trailing specimens, often appearing as streaks of glassy crust. This is seen with Chelyabinsk. With this piece, the pebble like pieces hanging on the outside maybe a result of a piece breaking up late in flight with some small bits from it gathering on on other hot trailing specimens in flight. 2-cents from JD |

One of the many things I love about meteorites are the mysteries they present. Our Universe is so filled with surprises!
If this was not an observed fall, and I happened to come upon these meteorites, I am not certain that I would initially recognize them as meteoritic in nature. (And I have been doing this a long, long time!) |

Great photograph of and intriguing feature! |

I am note sure if these "different" specimens are actually "thick frothy fusion crust with H5 fragments embedded". I would think this is impact melt that was present before the meteoroid entered the Earth*s atmosphere.
Anyway: Great pictures of a great specimen, Gregor. |
