Chemical evidence for the pairing of some iron meteorites.

On the basis of compositional evidence from abundances of Ni and noble metals in iron meteorites, pairings of a number of meteorites were examined. It was concluded that: in group IIICD, Carlton is paired with Lamesa; in group IIB, “Onnum Valley” (DP88020) and “CM66” (DP88023) are paired with the Derrick Peak shower; in group IVA, Railway and “G2011” are paired with Gibeon; and in group IIIE, Paneth's Iron is paired with Coopertown rather than with Burlington or Staunton.
