[meteorite-list] Questionable Unclasified Stone. Brecciated???

[Erik Fisler]

Hello List,
  At the Tucson Show this year I purchased a few unclassified chondrites from Dima. One of them has very interesting oblation pits that creat ridges.  Is this because the stone is most likely brecciated?
Or just an interesting fenominom?
