Hi Jeff, Stefan & All,
I know that some scientists even think that oxidized CVs and CKs should be
considered as one single group of meteorites, and pour Tanezrouft 057 that
was classified C4 is an example as some parts of appear to be CV and some
other ones CK, according to the analyses that have been processed. TNZ 057
is still under study and we hope that something will come out one of these
days but there was already an abstract written by Dr Bertrand Devouard
(UBP - Clermont-Ferrand - France) that you can find on our website at:
http://info.meteoriteshow.free.fr/Archives-Meteoriteshow/angl/Tnz057/abstract-Tan057-B.Devouard.pdf.
But anyway and even if Stefan's meteorite is obviously different from TNZ
057, i believe that there is a possibility that part of it can be CV and the
other part CK (but both of them can be CV as well...). The best is to have
it analyzed.
Kind regards
Frederic Beroud

Hi Stefan and all,
I was thinking about this last night and was wondering if anyone knows of
a Carbonaceous chondrite that has ever been classified as a combination?
(i.e. CV/CK or CB/CH etc.)
Or maybe a paper written on the topic?
Cheers,
Jeff

Hello Together,
many thanks for the all the interesting answers to my email. Yes, it
could be a CK/CV - if I look at Marcins photos of his NWA 4838, the
pieces are actually very similar, although certainly not the same
meteorite. Here are the two photos side by side:

The dark lithology could be a melted version of the light-grey lithology.
But it is somewhat strange that the dark lithology has apparent more free
iron metal than the light-grey area. I will of course keep the list
informed about the final classification. The stone is currently under
examination by Dr. Ansgar Greshake. Whatever it is, it is simply a
strange thing, and a great surprise indeed.
Best wishes,
Stefan

Hello Fred, Stefan and List,
"The darker side looks like a CV3, but the fair grey one?"
The uncut main mass: http://www.chladnis-heirs.com/carb-ungesch.jpg
The cut surface: http://www.chladnis-heirs.com/carb.jpg
Ever since Stefan first showed me this unique specimen in November 2008,
I've been wondering and brooding what this might be. My very first idea
was
that this might be a CK-like chondrite, then I thought it might also be
some
kind of E-chondrite and from there, it was just another (hypothetical)
hop
to the assumption that this could be a Kakangari-like chondrite (???)
What do you think?
Bernd
