That observation I didn't made.
Some have shock veines, some not.
Anyway shock veines are a result of impacts on the parent bodies,
so if there are more veines in Dhofars, it's just by chance.

Dhofars have more cracks than Saharian W3-4.

Hi Martin,
Thanks for your observations on Dhofar vs. NWA. What you wrote makes sense.
However I still wonder why many of the Dhofar chondrites have so many fine
shock
veins compared to the NWAs. Any thoughts?
Bob

Hi Bob,

>So we have two reasons:
The more harsh weathering conditions in Oman
and a economical one, that from the NWA one sees only the tip of the
iceberg's weathering scale, cause the more rotten stuff doesn't sell.

Buckleboo!

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
