Abstract. Nickel belongs to the transition metal family and shows close chemical similarities with Fe and Co. Even more than these elements, it is concentrated in silicated FeMg minerals by octahedral substitution with Fe 2+ ions. Thus, the mean mineral/ matrix partition coefficient of Ni is, and for basaltic whole rocks, for olivine, and orthopyroxene and clinopyroxene, respectively.
