Experiments on the partitioning of Mg2+, Ca2+, Mn2+, Fe2+, Co2+, Ni2+ and Zn2+ between olivine (forsterite and fayalite) and 2 N aqueous chloride solutions were performed in the temperature range of 500 to 800°C, 1 kb.<br> The partition coefficient, which is defined as KPN(Fo)=(XMe<sub>2SiO4</sub>/XMg<sub>2SiO4</sub>)/(mMeCl<sub>2°aq</sub>/mMgCl<sub>2°aq</sub>) or KPN(Fa)=(XMe<sub>2SiO4</sub>/XFe<sub>2SiO4</sub>)/(mMeCl<sub>2°aq</sub>/mFeCl<sub>2</sub>°aq), vs. ionic radius (PC-IR) diagrams are drawn based on the experimental results. In the case of forsterite, the PC-IR curve has a local maximum near Ni2+ and shows a concave curve in the region of larger ionic size. However Zn2+ deviates from such a trend. In the case of fayalite, the PC-IR curve shows a convex curve with a peak near Ni2+ except for 500°C. Also in this case, Zn2+ deviates from such a trend. The anomaly of Zn2+ may be attributable to its tetrahedral site preferency. The KPN value for Ni2+ decreases with increasing temperature, whereas those for the other elements except for Ca2+ increase. The optimum ionic radius for forsterite and fayalite seem to increase slightly with increasing temperature.
