"I have some plots here of Ni concentrations in Earth rocks compared

 Ni in the range of terrestrial rocks. That's because they don't have (much)
 FeNi metal"

Interestingly, this "trend" is also reflected in oxygen isotopic ratio plots, where
the HEDs plot close to the TFL line and and Lunars plot on it. Just like in Randy's
nickel plot, the SNCs plot slightly above the TFL line.
