Pierre and Rob,

Thank you for responses about NWA 900 and 995. Melt, and not carbonacous for
900...that is cool too...since I really like melts. We all look forward to
more information on these. (Matteo...do you still think you have seen
achondrite clasts?...in another slice maybe?

Question...has anyone suggested the same(achondrite clasts) for 869? That, I
have not heard of.

Greg and Adam...are you out there? What is the status on the "collection in
a slice", or NWA 904?

Now I'm (pretty) sure there are achondrite clasts in the 904 slice I
have...but if I've learned anything is that we should wait for the analysis.

John

PS Side note...my thin section of 869 from Jeff Rowell looks like I have an
L3+ something clast in a L5 or L6 matrix. Probably the slice is a brecciated
chunk of L6 clast with a chunk of L3+ matrix in the middle. See how we get
turned around. (Al...I used criteria 7 and 8 from page 87 of the "Norton
Encyclopedia" to come up with my own classification). This is kind of
fun...but I'll stick to engineering.

PSS Dean...by the way, you do have the best buy out there!
