  1. 28. Composition, physical properties, and thermal state of the core
    Prof. Eiji Ohtani (Tohoku University)

    Recent advance in high-pressure mineral physics of the Earth’s central regions are reviewed. The density of the core is lower than that of pure iron under the core conditions. Recent analyses of the equation of state and the sound velocity of solid and liquid iron and iron–nickel alloys strongly suggest that the core contains light elements. Possible candidates for the light elements in the...

    The Earth is differentiated and chemically heterogeneous planet. Chondrites, undifferentiated meteorites, have been used to estimate the composition of the Earth. Chondrites are similar in composition to the Sun except volatile elements. They have been considered to keep the composition of the building blocks of the Earth regarding refractory (not volatile) elements. Because both parent and...

  3. 23. Last and next decade in geoneutrino measurements.
    Fabio Mantovani (INFN - National Institute for Nuclear Physics)

    In July 2005 KamLAND collaboration claimed the first evidence of geoneutrinos on Nature journal. After a decade of measurements, KamLAND (Japan) and Borexino (Italy) experiments confirmed that the technology is ready to measure the geoneutrino signal with enough statistics for answering some fundamental questions of Earth Science. Taking into account that SNO+ (Canada) and JUNO (China)...
