PGE occur only in overlying meagre disseminations (Pt-Pd-Au), and reach the highest concentrations in chromite-rich rocks (Os-Pt-Pd) at the roof. The distribution of PGE in these intrusions has an unusual pattern. Disseminat

The relative roles of primary and secondary fluids in the concentration of the PGE in Shetland are difficult to determine because the chromite-rich lithologies characteristically lie in altered, highly serpentinized zones.
