Jeff,
Thank you for the explanation and clarification that clans do not necessarily
tie two groups together...though they are thought to be related due to
similarities. So it goes something like this... (with a few questions at the
bottom).
Jeff,
Thanx for keeping me and I'm sure many others straight on these issues. We as
a group are too loose about meteoritic nomenclature, and I think many(non-
scientists especially) out there who publish work need to pay attention to
these and other common practices in naming. Much of my
David and others,
In reading the article on Bencubbenites I have two comments.
1. This is the first time I recall the description of the rounded metal
blobs, blebs, nodules as being referred to as metal chondrules. Did anyone
else notice this? The statement says something like The metal and
G'day List,
I'm hoping that someone may be able to clear this up. HAH 237
is formally classified as being a CH (petrologic type 3) chondrite and S3, W2.
However, I've seen itlisted on many websites as a CH-BEN (Metal rich
Bencubbinite). I thought that CB or Bencubbinites are now a separate

In this abstract, Mrs. Russell calls it CH-like. J.A.
Thanks, Bernd, for your interesting answer. So both the papers by
Russell and Greshake tell us of a chondritic grouplet called CB, while
on the other hand the very latest version of MetBase (V6.0, issued
this summer) still has the CH-BEN type classification, and not CB.
Now, what makes me wonder

So my question is: is the CB designation still just a proposal (made
by the authors of these papers, and may be others), and has yet to
arrive at a status of general acceptance by the scientific community?
Should CH-BEN be abandoned? Are both of them valid side by side

I'm as confused about these groups as everybody else. Here's what I can add:
The NomCom does not make official decisions about meteorite groups. In
fact, nobody in the Meteoritical Society does. It's just a matter of
accepted usage. Joern Koblitz does what other editors, including the

Here is the link to the paper by Weisberg, Prinz, Clayton, Mayeda,
Sugiura, Zashu, and Ebihara in which they propose the designation of the

such awesome work but I have the highest respect for what they present
