Element partitioning between Mg- and Ca-perovskites and anhydrous calcic ultrabasic melt was studied experimentally at 25GPa and 2200°C. The observed partitioning relationships in this system are similar to the results of previous studies in magnesian ultrabasic and basaltic systems, and are consistent with predictions based on crystal chemical considerations. These results provide new insights into early global mantle differentiation, and kimberlite petrogenesis from the lower-mantle source regions.
