Osmium, Ir and Ru behave as compatible elements during partial melting and crystal fractionation, whilst Pt, Pd and Rh behave as incompatible elements. This produces a fractionation of the platinum-group elements (PGE). There is a debate as to which mineral or minerals control Os, Ir and Ru (referred collectively as the Ir platinum-group elements, IPGE). Chromite appears to have an important role in concentrating these elements, because chromite-rich cumulates from mantle and crustal settings tend to be enriched in IPGE and in basalts and komatiites there is a positive correlation between Cr and IPGE. Broadly speaking there are two mechanisms that have been suggested whereby chromite could concentrate IPGE: i) these elements could partition...
