Fig. 4: Stability of Bdm in MgO-SiO2.
From: Phase relations of bridgmanite, the most abundant mineral in the Earth’s lower mantle
A Phase relations in Mg2SiO4 system at 19–27 GPa and 1000–3000 K. Red: Bdm, marron: Rwd, light green: Wds, blue-green: Per, yellow: melt. Triangles and diamonds: Chanyshev et al.49, circle: Liebske and Frost63. The boundary between Rwd and Wds is the extrapolation of Tsujino et al.68. B Melting relations in Mg2SiO4 at 24 and 136 GPa and 2000–8000 K. Modified from Yao et al.69.
