Hi Greg,
The NWA 7034 "main mass" is the original ~320g single stone "Black
Beauty" that I started working on back in August of 2011. For a while
I thought it was the only one in existence, but over the past few
months more stones, all smaller than 320, have been recovered. The two
additional stones that I have personally inspected are 107.5g and 65g.
So that is 492g, plus the 84g pairing NWA 7533 (which by the way is
geochemically identical to NWA 7034 and clearly from the same
meteoroid). I have recently seen photos of additional stones, so you
are correct that the Black Beauty TKW is probably a bit more than 1kg.
When the dust settles, I hope to revise the NWA 7034 write-up in
MetBull and list the TKW. Personally, I think it is very confusing to
have a bunch of NWA# pairings, when all these stones are so clearly
pieces of the same rock, they are unlike any other meteorite both in
hand sample and geochemically.
By the way, we will be presenting new data at LPSC (not in the Science
paper) on noble gases that have been measured in NWA 7034, which are a
match for Viking measurements of Martian atmosphere. Also the cosmic
ray exposure age is likely ~5 my, the size of the NWA 7034 meteoroid
in interplanetary space (before Earth entry) is estimated at diameter
~50 cm, so anyone hoping that there are many 10s of kg of Black Beauty
on the ground in the Saraha will be disappointed.
Thanks,
Carl Agee

Hi Carl,
It is lunch time for us Floridians so I am just taking a break and munching
on some SNACS...
Seriously, What is the current count of NWA 7034 'official' pairings and how
many stones constitute each of those? We have all heard of 'paired' stones
making the current stone count at about a dozen or so "IF" they are indeed
paired to NWA 7034. We have been hearing and seeing images of stones offered
from Moroccan dealers as pairings.
If I read it all correctly, the original single 320g stone was the first
"NWA 7034" one. Are the three stones pictured in all of the press releases
part of one stone that adds up to 320 grams? If not, what are the weights of
the additional two stones and/or do they each have their own NWA numbers?
Also, I heard there is a 240 gram stone with the owner of the first 320g
stone, has this been confirmed yet?
The only 'officially' paired stone that I am aware of is NWA 7533 weighing
in at 84 grams.
If all of the stones that are 'guaranteed' paired to NWA 7034 by Moroccan
dealers, the combined weight is exceeding 1000 grams which is pretty cool
for such a unique meteorite!
Congrats again to all involved in bringing this new Martian meteorite to
light!
Best Regards,
Greg

Jeff,
Now that you are at NASA you can appreciate the perverse things people
do with words just to come up with a cool acronym. Making the new
Martian meteorite acronym even half way cool requires some drastic
measures, like giving NWA 7034 Basaltic Breccia Black Beauty a new
name based on locality: I propose "saharaite". So we now have the
meteorites from Mars or "SCANS"
S: shergottite
C: chassignite
A: ALH 84001
N: nakhlite
S: saharaite
Enjoy!

Don't forget ALH 84001, the pyroxenite.
SNCPB?
If we use the N from NWA instead of B, and the A from ALH, how about CANNS?
Or maybe we should just do the sensible thing and call them Martian
meteorites?

Hi Paul,
I like the "SNCB". It sounds like a radio station's call
letters...Stay
tuned for all of your Martian meteorite news from SNCB.
Regards, Fred H.
How shall we organize the new class of Martian?
Until now it has been SNC
How about B or B squared for BASALTIC BRECCIA ?
SNCB
What say you all?
