Evidence from the paper
Table 1: (Mg1-yFey)O: rho (g/cm3) = 3.583 + 2.28y; K_S (GPa) = 162.5 + 11.5y; K_S' = 4.1. Footnote b: 'Results from Duffy and Anderson [55].' Text: 'The thermoelastic parameters for Mw used for the current study are also summarized in Table 1, which are derived from MgO after correcting for the effect of iron based on previous studies (e.g., [28-32]).'
