It is widely believed that the formation of the Earth's core could induce dramatic changes in various geochemical and geophysical aspects of the Earth. Series of recent studies have revealed that the environmental condition for the Earth's surface can change through the core formation, and therefore, formation or evolution sequence of the Earth's core was still key issue to understand the overall evolutional history of our planet. To decode the hidden formation sequence of the Earth's core, such as timing and duration of the core formation or possible changes in the chemical composition of the core, we have tried to derive direct elemental information concerning the distribution among the inner-core, outer-core and mantle using a combination of newly developed in-situ analytical technique and the sophisticated high-pressure experiments.
