Hi Jeff,

I've been puzzled about what you said and perhaps I've misread or missed your comments. Why do you think the R chondrites should be included in the oc clan (rather than the carbonaceous)? I thought this was a very unique idea.


Thank you all for this interesting topic.

Carl

conservative colleagues are normally willing to accept, I would say that
the rarest group of OCs is the R chondrites (only ~100 are known and
many of those are paired).In addition, a number of unique ungrouped
meteorites are OC-like.But again, I don't know of any colleagues who
agree with me that R chondrites are in the OC class. [I would say that
the OC class has two clans, the H-L-LL clan and the R clan].
