[meteorite-list] Dhofar vs. NWA meteorites

[Bob King]

Hi all,
I've seen a good number of Dhofar and NWA common chondrites and 
I've noticed that there are many among the Dhofars which exhibit highly 
weathered interiors laced with rich, thread-like shock veins. These 
veins seem to be far less common in NWA chondrites and I wonder 
why. Can anyone shed light on this little mystery (for me)? Thank you!
Bob
