TABLE 1 Values of input parameters for MgO, hcp iron, Earth lower mantle and Earth outer core taken from References [1, 9, 11, 27]: MgO K0 (GPa) = 162, K0' = 4.15, K'inf = 2.49, gamma0 = 1.54, gamma_inf = 1.08. 'The P-V relationships are determined using the generalized Rydberg-Vinet EOS taking equations (15), (16) and (18).'
