The Pyroxenite Marker, a thin, orthopyroxene-dominated marker horizon, is observed towards the top of the Main Zone of the Bushveld Complex, where the last voluminous influx of magma into the Bushveld Complex is thought to have occurred. In an attemp

The Flatreef, a down-dip, sub-horizontal extension of the Platreef, which underlies the Turfspruit and Macalacaskop farms, represents the future of platinum mining in South Africa. The stratigraphic connection between the Platreef, located at the bas

The Platreef of the Bushveld Complex is one of three key stratigraphic units, along with the Merensky and UG-2 reefs, in which platinum-group elements are concentrated. The correlation between the Platreef and the stratigraphy from the western and ea

The Verena Granite forms part of the Palaeoproterozoic Lebowa Granite Suite of the Bushveld Complex and was named after the village of Verena in the Mpumalanga Province of South Africa. It occurs over an area of ~600 km2 and is intrusive into the Roo

The Bon Accord nickel body has been known since the 1920s to contain rocks with up to 50 wt% NiO. Numerous nickel-rich minerals have been described from this deposit. However, none of these minerals contains significant Cu or S, making the deposit ch

We present the results of a high-resolution mineralogical and geochemical study conducted across three intersections of Merensky reef at Impala Platinum Mines on the Western Limb of the Bushveld Complex. We studied two intersections of non-pegmatoida
