抄録

Element partitioning between mantle minerals (Mg-perovskite, Ca-perovskite, majorite, olivine) and coexisting silicate melt has been investigated at pressures 14 - 23 GPa and 2400 - 2600°C, by using 6-8 type multianvil high-pressure apparatus. The observed partition coefficients, D, were plotted on partition coefficient-ionic radius (PC-IR) diagrams. A peak was found at around 70 pm in the D-profile of olivine. It was difficult to identify peaks of D-profile in majorite/liquid and Mg-perovskite/liquid, but the profile of Mg-perovskite/liquid suggests a peak at around 70 pm, which may correspond to the 8-fold site of distorted perovskite structure. There was a bottom of the D-profile of Caperovskite/liquid at around 70 - 80 pm, and the existence of peaks at around 50 and 100 pm is expected from the observed D-profile. Partition coefficients of large ions, such as Ca and La, were large in Ca-perovskite/liquid.
