Title: Experimental petrology of the Earth's lower mantle

Speaker: Shigehiko Tateno (Associate Professor, Institute for Planetary Materials, Okayama University)

Abstract: Understanding of the building block of the Earth requires complete knowledge of the bulk composition as well as chemistry in the solar nebula. However, the composition of the lower mantle, inaccessible geochemical reservoirs with huge volume, has long been under debate. One approach is experimental petrology, aimed at experimentally simulating conditions within the Earth in order to understand the phase diagram of the relevant materials (e.g., mantle rock and chondrite materials) and the partitioning of specific elements between crystals and melts.
