Abstract
Abundant and diverse platinum-group minerals occur in the Rum layered intrusion, Inner Hebrides, Scotland. Platinum-group minerals are associated with chromite-rich horizons in both the Eastern and Western layered series, and are enclosed by Ni- and Cu-rich sulphides, or silicates. The most common phases are Pd–Cu alloys; Pt–Fe alloys; laurite (Ru(Ir,Os)S 2 ); sperrylite (PtAs 2 ); and Pt–Pd-bearing bismuthides, tellurides and antimonides. The mineralization on Rum is due to: (1) initial concentration in the parental magma linked to a high degree of melting associated with mantle plume activity, and (2) localized concentration due to magma mixing and subsequent crystallization within an open-system magma chamber.
