Abstract

Oxygen isotopic compositions have been used to delineate possible genetic relationships between various meteorite groups. Clayton et al. first noted similarities in O isotopic signatures between silicates in IIE irons and H chondrites, and between IVA irons and L and/or LL chondrites and suggested a possible common parent body in each case. However, since silicate inclusions represent a minor phase in IIE and especially IVA irons, we examined N isotopic signatures from the metal phase of these meteorites for comparison to N isotopic signatures in H and L/LL chondrites, respectively.
