Extended Data Fig. 7: Differences in the seismic properties between the single-perovskite phase (Ca-rich bridgmanite) case and the two perovskite phases (bridgmanite + CaSiO3 perovskite) case.

The differences of Ca-rich bridgmanite from bridgmanite + CaSiO3 perovskite are shown for bulk sound speed (Φ), bulk modulus (KT), and density (ρ) for the komatiitic composition at 300 K. The grey shades show the estimated 1σ uncertainties.
