    Magnetite in the unequilibrated CK chondrites ...

    Magnetite in CKs is compositionally distinct from CVs, particularly in abundances of Cr 2O 3, NiO, and TiO 2. Although there are minor similarities between CV and equilibrated CK chondrite magnetite, this is contrary to what we would expect if the CVs and CKs represent a single metamorphic sequence. CV magnetite should resemble CK3 magnetite ...
