Evidence from the paper
Table 4. Thermodynamic Data for the Mantle Density Models: 2(Mg0.9,Fe0.1)SiO4·Mg(OH)2 (Chondrodite): V0 (cm3/mol) 109.18, K0 (GPa) 136.2, K0' 3.7, θD 900.4 b, γ0 1.13 b ... b) Assumed to be the same values as for olivine. ... we have corrected the zero-pressure density of chondrodite for iron content
Additional notes
theta D
900.4 (assumed same as olivine)
gamma0
1.13 (assumed same as olivine)
note
V0 adjusted from measured 110.88 cm3/mol to account for iron content in the pyrolite model; K0 and K0' from this study's fit
