Compositional models of the core and lower mantle will be reviewed and assessed. Assumptions in the models along with constraints and uncertainties of the Earth’s interior will be presented. Although a compositional model for the lower mantle that matches that of the upper mantle for major elements is most compatible with observations and constraints, uncertainties are such that competing...

I review the seismological studies on the velocity and density in the Earth's core. I will introduce (1) how their models have been obtained, (2) how much uncertainties such models have, and (3) what is important future research topics.

Recent progress in theoretical and computational mineral physics based on the density functional techniques has been dramatic in conjunction with the advancement of computer technologies. It is now possible to predict phase stability and several physical properties of complex minerals quantitatively in the pressure and temperature conditions corresponding directly to the deep planetary...

Main part of the geomagnetic field is generated by dynamo process in the Earth’s core. This implies that the geomagnetic field and its secular variation have potential to reveal the dynamics of the Earth’s core. In this talk, I am going to introduce recent progress of the studies of Earth’s core using the geomagnetic field. It has been suggested that decadal variation of the...
