ich finde, dass der NWA 7034 und der NWA 2737 sich doch sehr ähnlich sehen, was sagt Ihr dazu?
By the way, we will be presenting new data at LPSC (not in the Sciencepaper) on noble gases that have been measured in NWA 7034, which are amatch for Viking measurements of Martian atmosphere. Also the cosmicray exposure age is likely ~5 my, the size of the NWA 7034 meteoroidin interplanetary space (before Earth entry) is estimated at diameter~50 cm, so anyone hoping that there are many 10s of kg of Black Beautyon the ground in the Saraha will be disappointed.
The NWA 7034 "main mass" is the original ~320g single stone "BlackBeauty" that I started working on back in August of 2011. For a whileI thought it was the only one in existence, but over the past fewmonths more stones, all smaller than 320, have been recovered. The twoadditional 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 isgeochemically identical to NWA 7034 and clearly from the samemeteoroid). I have recently seen photos of additional stones, so youare 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 inMetBull and list the TKW. Personally, I think it is very confusing tohave a bunch of NWA# pairings, when all these stones are so clearlypieces of the same rock, they are unlike any other meteorite both inhand sample and geochemically.
