Figure 1From: Sound velocity of hcp-Fe at high pressure: experimental constraints, extrapolations and comparison with seismic models XRD-derived compressional sound velocity as a function of density. Grey right-pointing triangles (Mao et al., 1998); dark cyan left-pointing triangles (Dubrovinski et al., 2001). Lines are linear fit to the distinct experimental data sets. The star is the ultrasonic determination reported in Mao et al. (1998). PREM is shown as crosses.Back to article page
