Partitioning behaviors of Mn, Co and Ni between iron hydride and mantle minerals (olivine, pyroxene and magnesiowustite) under high pressure were experimentally investigated at 1400°C and 3-11GPa. The present experimental results showed that the siderophile nature of Co and Ni, and the lithophile nature of Mn decrease under high pressures: all the observed metal/mineral partition coefficients, K'=(Xi/XFe)metal/(Xi/ XFe)mineral, i=Mn, Co and Ni, approach 1 with increase in pressure. K' also depends on the composition of the mineral phase: K' decreases with an increase in MgO mol fraction. From these experimental results, it is expected that the observed upper mantle elemental abundance may be explained by the equilibrium between metal and silicates under extremely high pressure.
