My guess is terrestrial weathering (W3 in Met Bul) that created a "rind" around the fragment/individual. I've seen weathering rinds with earthly fine-grained meta-basalts and diabases. |

Yes, I too would like to hear the possible processes for this outer formation to occur. Other than it crashed into a peanut butter factory. |

Interesting piece. John, do you know what that "rim" is around the slice? |
