Hello Pierre and all,

As far as I know there is no published data on NWA 978. It was purchased by
Mike Farmer in Morocco during July of this year. UCLA did the classification
and I assume it will be published in this years Meteoritical Bulletin. (I
keep hoping for a preview on their website).

At any rate, I have that NWA 978 is classified as a R3.8, S3/W2 whereas
NWA753 is a R3.9, S2/W2 so they differ slightly in shock stage and
petrographic grade.
Also, for what it worth, the matrix color on my pieces of these two
R-chondrites differs: it is brownish in NWA 978 and it is appears greenish
in NWA 753.

Regards,
Frank

Dear list

I have two enquiries

1. I just got on E-bay a slice of NWA978. A beautiful R3, no doubt! However
the seller just mention "classified by UCLA". Is someone aware of a
published account on this rare NWA? I am wondering about pairing with
NWA573...

2. a fellow collector has got a while ago from a US dealer:
El Tigre Mexico 1993 Dec. 23 L6
however it is not officially declared, a surprising situation for a
meteorite fallen 8 years ago. Anyone knows about this meteorite?
(it looks effectively like a fresh L6)

Thanks in advance!

Pierre
