Thank you all. I appreciate your input! |

superb SA John...the crust in the flared "crater" does confirm an earlier melting before this individual's ripping apart finished. WOW! |

That definitely took a big hit. As you say a great example of the forces involved. Love that there are so many types of SA specimens that tell the whole story of it's fall to Earth.

I agree with Andi's comment. For me the piece mainly looks like a torn fragment, but a part looks like a an individual piece with some fusion crust in the large "circular pit". In my opinion these pieces "half explosion fragment, half individual piece" are very rare and very exciting, and it would appeal to me to make a metallographic preparation (cut in half and do a macroscopic etch to see undeformed and deformed pattern) on such a rare piece. John, I congratulate you on such a wonderful S-A collection sample. I recomment you, don't cut it in two halves... :-) |

I guess the "circular pit" is more likely a big regmaglypt from an early fragmentation. So ablation created this pit not an explosion. It*s from the rim of a bigger individual. |
