Seismic velocities of CaSiO3 perovskite can explain LLSVPs in Earth’s lower mantle

Seismology records the presence of various heterogeneities throughout the lower mantle 1 , 2 , but the origins of these signals—whether thermal or chemical—remain uncertain, and therefore much of the information that they hold about the nature of the deep Earth is obscured. Accurate interpretation o...
