Fig. 6From: The sound velocity of wüstite at high pressures: implications for low-velocity anomalies at the base of the lower mantleSound velocities of wüstite under lower mantle conditions. The VP (a) and VS (b) profiles were calculated along the mantle geotherm (Brown and Shankland 1981). The red solid line represents the B1-FeO values obtained in this study. The dashed and dotted lines represent bridgmanite (XMg = 0.94) and magnesiowüstite (XMg = 0.79), respectively (Murakami et al. 2007). The bold line represents PREMBack to article page
