Controls on platinum group element variation in mafic and ultramafic magmatic systems

Summary

This study investigated the mechanism of platinum-group element (PGE) fractionation in ultramafic systems, focussing on the role of chromite.

Samples from a wide range of occurrences were analysed to assess potential controls on PGE behaviour such as geochemical affinities, age, emplacement styles, metamorphic grade and nickel sulphide mineralisation endowment and style.
