Session LanguageEE
ScopeLiquids of silicates and metals inside of the Earth have played important role in the physical, chemical, and thermal evolutions of our planet. This session aims at understanding the physical and chemical properties of liquids from shallower to deep parts of the Earth, which are strongly related to the long history of the Earth's from the planetary accretion to the present-day dynamics. In addition, we call for presentations by researchers from various backgrounds of geochemical, experimental, theoretical/computational, and seismic/geodynamical ones, who investigate the physical and chemical properties of liquids and the behaviors and roles inside of Earth. Relevant topics include, but are not limited to, partial melting and melt extraction, liquid-solid partitioning, high pressure experiments on melts, and seismic detections of mantle melts and outer core anomaly.
