Abstract
All analysed massive chromitite layers of the Critical Zone of the Bushveld Complex are enriched in PGE's over their silicate host rocks. The concentration factor has been found to increase with stratigraphic height. The PGE-distribution of the Lower Group and Middle Group chromitites shows a systematic relationship to the chromite mineralogy of the chromitites. The LG1- to LG4-chromitite layers are characterized by the dominance of the Ru-group elements (Ru, Os, Ir). The LG5- to LG7-chromitite layers contain almost equal amounts of the two PGE-groups and in the MG-chromitites the elements of the Pt-group (Pt, Pd, Rh) are the most abundant. The chromite mineralogy subdivides the chromitites in a similar way.
