In addition to the observed phase ‘Egg’+ stishovite association,
some CaSi-perovskite grains and numerous majorite grains have
been shown to contain either positive or negative Eu-anomaly, in
their REE distribution curves (Figs. 7 and 12). These anomalies may
relate to the composition of subducted lithosphere, and such anomalous
grains, most likely, belong to the ‘eclogitic’ association.
