Fig. 5

Pressure-transverse acoustic wave velocity (P-V S ) profiles up to 40 GPa. a SA1 (blue squares, this study), SA2 (light blue diamonds, this study), SiO2 glass (red circles, Murakami and Bass 2010), and MgSiO3 glass (green triangles, Murakami and Bass 2011) up to 40 GPa. b Regression curves of SA1 and SA2 fitted by polynomial functions. P-V S plots of SA1 from 11 to 60 GPa are fitted with a fourth order polynomial (R 2 = 0.9933) and P-V S plots of SA2 from 10 to 59 GPa are fitted with a quadratic function (R 2 = 0.9957)
