Birch–Murnaghan parameters for reference density profile.

Mineralogy	K₀ (GPa)	K′	ρ_s (kg m⁻³)
Upper mantle	163	4.0	3240
Transition zone	85	4.0	3226
Bridgmanite	210	3.9	3870
Post-perovskite	210	3.9	3906
Melt	30	6.0	2750

Notes. K₀ is the bulk modulus at pressure P = 0, K′₀ is the pressure derivative of the bulk modulus at P = 0, and ρ_s is the surface density.
