Hi Mike and List,

Mike asked:

"I would like to know if any other Pallasites have ever been
found in NWA? This stone only weighed 53 grams and was 100%
complete. ... This to my knowledge is the only Pallasite
from North West Africa. Can anyone give me any more information?"

I just scanned through Meteoritical Bulletins 84-87 + the
preprint for 88, and suprisingly no NWA pallasites have been
reported there. Of course, with all the reserved provisional
numbers that have not appeared in the Bulletins, there could
be a another pallasite waiting in the wings. But if so, I
think we would have heard about it on the list.

So congrats on uncovering the first! Given all the eucrites,
diogenites, howardites, ureilites, R-chondrites, martians,
lunars, acapulcoites and even a few irons and winonaites
that can be found among the NWAs, it is frankly surprising
that no pallasites have been uncovered until now. Indeed,
are there any other groups that are not yet represented by
an NWA? Don't recall seeing a lodranite, but there might
have been one. And what of mesosiderites? I believe the
Hupes announced at least one recently, but was that the
first? --Rob
