Thanks a lot for the information, Carl.

I can't wait to read more in six days.

Does the CRE-age of ~5 My mean that NWA 7034 probably represents a new impact event or could it somehow be related to the shergottites Y793605 and Y000027 with their ejection age of ~4.70 ? 0.50 My?

Best regards,

Martin

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
