Research Abstract

Behaviors of iron and iron-bearing minerals have been studiedby both multianvil and diamond anvil cell experiments, in conjunction with ab initio calculations, under the pressure and temperature conditions from the deep lower mantle to the inner core of the Earth. A number of important results such as relevant to the partitioning of iron in the lower mantle and the phase relations of iron in the inner core, as well as technological developments in applying nano-polycrystalline diamond (NPD or HIME-diamond) to various high-pressure apparatus, have been obtained in this study.
