Chemical interaction of Fe and Al2O3 as a source of heterogeneity at the Earth's core-mantle boundary
Seismological studies have revealed that a complex texture or heterogeneity exists in the Earth's inner core and at the boundary between core and mantle. These studies highlight the importance of understanding the properties of iron when modelling the composition and dynamics of the core and the interaction of the core with the lowermost mantle. One of the main problems in inferring the compositio
