Four antarctic meteorites (ALHA81005,Y-791197,-82192 and -82193) have been identified as lunar meteorites. We investigated the REE, Rb, Sr and Ba abundances and major element compositions in specimens spearated from Y-791197 and -82192. Furthermore, we have discussed the genesis of these lunar meteo...
