We used radiochemical neutron activation analysis to determine Ag, As, Au, Bi, Cd, Co, Cs, Cu, Ga, In, Rb, Sb, Se, Te, Tl and Zn in interior portions of 5 Antarctic meteorites-ALHA76004 (LL3), ALHA77081 (Acapulco-like), ALHA77219 (mesosiderite?), ALHA77307 (C3V), ALHA78113 (aubrite)-and Acapulco chondrite. Where comparison is possible, all data for these weathering type A and B ALH meteorites and for 4 others agree well with data for corresponding non-Antarctic meteorites. These agreements are at least as good as those involving only non-Antarctic L6 falls demonstrating that type A and at least some type B ALH meteorites provide compositional data yielding important genetic information. As an example, compositions of Acapulco-like chondrites differ from that of a forsterite (F) chondritic inclusion in Cumberland Falls. Therefore, at least two chondritic groups occupy the compositional gap between E and H chondrites.
