"Do CV's contain nickel"?

Here's what Jeff Grossman wrote on Monday, April 19, 1999:

In fact, Allende has almost no metal, if what you mean is metallic Fe-Ni.
Jarosewich (1990) measured ~0.5 wt% metallic iron plus nickel in Allende.
Most of the metal in these oxidized CV3 chondrites is the high-Ni alloy
awaruite. There was once low-Ni metal (kamacite), but late stage oxidation
has destroyed it all. There is a big debate going on as to whether this sort of
process happened during parent body aqueous alteration or earlier, in the solar
nebula.
