Nitrogen isotopic compositions in the bencubbinites (Bencubbin, Hammadah al Hamra 237 (HH 237) and Queen Alexandra Land 94411 (QUE 94411)) and in a petrographically similar chondrite Grosvenor Mountains 95551 (GRO 95551) were measured by stepped combustion-static mass spectrometry. HH 237 and QUE 94411 contain isotopically heavy N, but not as heavy as that in Bencubbin or Weatherford. GRO 95551 contains isotopically near-normal N and light N and hence it is not related to the bencubbinites, as also indicated by its oxygen isotope composition. The N carriers in these meteorites were investigated using secondary ion mass spectrometry (SIMS). In the bencubbinites, N is mostly located around sulfide in metal clasts and in impact melt areas. The N carriers in the former are taenite and/or carbide, whereas those in the latter are molten metal, tiny graphitic carbon in metal and/or oxi-nitride glass. N in the various N carriers is isotopically equilibrated, and therefore the carriers are not pristine presolar grains. Isotopically near-normal N in GRO 95551 is located in graphite. The carrier of isotopically light N in GRO 95551 has not been found.
