Hi John and List,

Regarding classification of some of these similar-looking NWAs with
unusual clasts, John Divelbiss wrote:

I can add a little info on NWA 995 as I supplied UCLA (Rubin) with
type specimens on January 29th. The original mass of NWA 995
was a single stone of 222.9 grams, of which I turned in 19.0 grams,
plus an additional 9.9 grams from Brad Sampson. So eventually we'll
have a solid classification on this particular stone, which is a
chondrite breccia of some sort. UCLA is still getting their new
microprobe up and running, and with the upcoming Meteoritical
Society meeting there in a few weeks, I doubt much progress can
be made before August. Once I have a classification, I'll be sure
to forward it to the list.
