Zoning patterns of trace elements (TE) in minerals from Ca-, Al-rich inclusions (CAIs) may reflect how they formed [1] and/or yield information on secondary processes. We have measured abundances of the REE, Ba, Be, Sc and Ti in a single melilite (Mel) crystal (Xl) from the mantle of the Allende type B 1 inclusion Egg-6 [2] and in the rim of a coexisting clinopyroxene (CPX) at the core/mantle interface. TE zoning profiles in Mel from Egg-6 are compared with those predicted by [1] for fractional crystallization of Mel in type B CAIs.
