Density structure of Earth’s lowermost mantle from Stoneley mode splitting observations
Large-low-shear-wave velocity provinces (LLSVPs) are present at the core–mantle boundary. Here, the authors show that splitting of Stoneley modes is probably due to a lower density of LLSVPs than the surrounding mantle because of the presence of post-perovskite, chemical heterogeneity or both.
