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
