Extended Data Fig. 8: Heterogeneous nucleation with the embryo of bridgmanite nucleating on periclase in parent-phase silicate liquid.
From: The potential for bridgmanite megacrysts to drive magma ocean segregation
a, Schematic of heterogeneous nucleation configuration. b, Contact angle as a function of pressure along the peridotitic (dashed line)22 and chondritic (solid line)21 liquidi. c, The ratio of apparent interfacial energy to homogeneous nucleation interfacial energy for various contact angles and x is the ratio of the periclase crystal size R and critical nucleation size (r*), x = R/r*. The red-shaded region indicates plausible values of contact angles from b.
