[meteorite-list] Stan's NWA 2965 EL6/7 and achondrite vs chondrite

[MARK BOSTICK]

Hello Stan,

You noted, "the classification of this stuff as a 6/7 is SO 5 minutes ago. 
it's an EL3..."

Would it not be fair to say it is an EL6/7 with EL3 clasp material and most 
of the material is the EL6/7? I have made a comment or two on this before, 
recently with Dimmitt, that I do think it is right to give a meteorite with 
more then one petro type the 3 number, when it is not the dominating matrix.

This is more because of the commercial aspect then the scientific aspect. 
Usually a meteorite with a 3 will sell for several times what a 5-6 sells 
for. Then again, I guess petro 3 chondrites don't command the dollar they 
did 5 years ago, so maybe this doesn't matter to anyone other then me. I 
would hate to see some future scientist or student grab an L5 piece of NWA 
869 and an H5 part of Dimmitt and create some paper of type 3 chondrites.

On NWA 2965, or whatever name is eventually gets I was pretty much ignoring 
the classification as I am not sure how final the EL3 is, or more so, how it 
will appear in the Met. Bul.

So I guess I like what Weir has labeled the meteorite.

"The light grey/blue lithology material - while typically referred to as the 
'fresher' material by Moroccan sources is apparently the more aqueously 
altered of the two lithologies."

Interesting, I would have guessed along with the Moroccan dealers. 
Especially since you do not see the oxidized metal veining in the lighter 
material.  Maybe I should run my larger slice under water for a couple 
days...;^)

Thanks for the neat auction. I will be giving away the pieces I accidently 
broke off shortly and trying to sell the meteorite next week at half 
price....just joking.

Clear Skies,
