I think the Weisberg divisions are by no means in general usage.
Meteorite classification is chaotic and there is no standard system. I
wrote most of the wikipedia article on this subject:
http://en.wikipedia.org/wiki/Meteorite_classification
Take a look at the discussion there, which is fairly thorough. If I had
to vote for the best scheme, I'd go for the one proposed by Krot et al.
(2003), with there being two major divisions, chondrites and nonchondrites.

Hi all,
I am looking for some information in regards to the Division of
Meteorites in the currently used classification scheme.
It is my understanding that there are currently 3 divisions that all
meteorites fall under....or at least at one time there were three.
Chondrites, Primitive Achondrites and Achondrites.
1. Referencing Weisberg et al: Systematics and Evaluation of
Meteorite Classification, has there been any divisions added since
this document was printed? Are there still only 3 divisions?
2. Is there a more up to date schema or diagram which supersedes the
document above? I know there are changes in the IAB complex groups
and grouplets, referencing a document by Wasson accepted in 2002, are
there other changes?
Thank you for any info on this.
Kind Regards
Jim Wooddell
