[meteorite-list] urelite origins

[Marc D. Fries]

Greetings

   I've got a meteorite question.  Having seen enough Raman data to be
convinced that the diamonds in urelites are formed by shock
compression, I'm wondering - does anyone have an opinion on what sort
of meteorite they started out as?  They had to have been carbonaceous
meteorites of some sort to begin with, but the articles I've seen don't
seem to offer a clear picture of what they were like before they were
shocked.  CM, perhaps?

Cheers,
MDF
