　　The Earth’s deep interior would have been a fantastic object of human being in old days somewhat like the space studded with innumerable twinkling stars. Since the early 20th century, however, it became an object of “corroborative” science by development of seismology. The solid Earth was divided into three major portions, the crust, mantle, and core according to the discontinuous variations of seismic velocities with depth. Following these progresses, high-pressure experimentalists including myself tried to interpret the seismic information in terms of material science by realizing the similar conditions to those of the deep Earth in a laboratory. By the end of last century, high-pressure Earth science revealed quantitative constitution of the mantle down to beneath the 660 km discontinuity, or the top of the lower mantle. Recent seismic tomography of the deep mantle, on the other hand, visualized the pattern of large-scaled material transportation in the whole mantle, which has led us to firm views that the driving forces of both the plate tectonics and the mantle plumes, typical outcomes of the dynamic Earth, originate in the lower mantle.

　　Under these circumstances, my research interest is focused on acquisition of experimental data essential to elucidate the dynamic structure of the lower mantle which includes phase equilibria, element partitioning, equation of state, and other physical properties of the constituent materials. I have been carrying out melting experiments on the mantle rock and the primordial material at high-pressure, because the melting relations and element partitioning between melt and liquidus phases are indispensable to simulate the early differentiation of the Earth in magma ocean. In order to perform these subjects quantitatively up to pressures ca. 100 GPa, we have also been engaged on innovation of Kawai-type high-pressure apparatus equipped with sintered diamond anvils.

　　By combining the high-pressure experimental data with seismological and geochemical information, we will tackle following topics; the fate of descending plate in the lower mantle, origin and material source of the deep geochemical reservoir, energy source of the mantle plume, formation of the central core and mantle fractionation process in the early Earth.
