Concerning NWA 869
I have in my possession tree fragments:
- m1 = (630 � 0,5) g that I bought from Dean Bessey
- m2 = (65,4 � 0,1) g bought from Walter Branch
- m3 = (41,3 � 0,1) g bought from Walter Branch

Okay list, time to make yourselves useful...
Everybody wants the NomCom to publish and make official the name NWA 869.
So please, if you know anything, help contribute to the facts so I can
produce a writeup for submission to the committee.
Here's what I've got:
* At least 400 kg of material has been sold out of markets in Morocco
under this name.
* Alan Rubin classified a piece. It was a fragmental breccia, probably
L4-6. A thin section of L5 material gave Fa24.2, S3, W1.
So what's the rest of the story? How much is out actually there? When
did it appear on the market? Is it all coming from one finder/dealer? Is
the find location known? Is it really L4-6 (is this the right range)? Is
it all coming from the same fall, or is the name NWA 869 a garbage can for
all kinds of unclassified ordinary chondrites? What large stones are in
collections? Are other NWAs paired with 869? Which?
Please reply to the list only... I don't need a separate copy.
