Abstract
Near solidus equilibria in the system mantle peridotite-carbonate-phos phate doped with Ce and Yb have been studied at 20 kbar and 950-degree s-C. Carbonatitic melts in this system may be quenched into homogeneou s glasses. Such melts intensely extract REE from rock-forming mantle m inerals, and their migration may cause processes of mantle metasomatis m.
