Figure 10.

(a-c) Plot of relative depletions of Ni (CI-normalized) versus Mo, W and V calculated using Eq. 2 for the least evolved irons of the IVB, SBT, IIC and IVA groups and Wiley (Walker et al., 2008; Hilton et al., 2019; McCoy et al., 2011). Blue symbols are the CC bodies and red symbols are the NC bodies. The arrow is the direction that the composition of the parent body will progress with increasing oxidation. Data for the IIC and IVA (NC) group irons generally indicate a less oxidized parent body than the other CC type irons.
