Abstract

Melting of Earth's inner core David Gubbins and colleagues present geodynamo simulations showing that variations in heat flow at the core–mantle boundary are transferred to the inner core boundary. They find that the variations can be large enough to cause heat to flow into the inner core and, if this were to occur in the Earth, to cause localized melting. Such melting would release heavy liquid that could form a variable composition layer, providing a simple explanation for seismic velocity anomalies seen immediately above the inner core boundary. Localized melting and freezing could also provide a mechanism to create seismic anomalies in the inner core itself.
