Figure 8
Longitudinal and shear wave velocities of (Mg0.91Fe0.09)2SiO4 ringwoodite at high pressure and high temperature obtained from measurements in the present study. The solid lines show the calculated velocity change from the elastic parameters obtained in this study, where the bulk and shear moduli under high temperature and high pressure are calculated with the multinomial fitting described by Higo et al. (2008). The dashed lines are those determined at room temperature by Higo et al. (2006), while the small filled pentagons with error bars are the data of Sinogeikin et al. (2003). |
