Rooiberg Group volcanics The Rooiberg Group volcanics, which are up to 3.5 km thick in the Loskop area, are preserved over an area of > 50,000 km2 (Schweitzer et al, 1995) and may even have exceeded 300 000 km3 (Twist and French, 1983) although in many areas the succession is extensively thinned or removed by erosion (Buchanan et al,

A layer of the Bushveld Complex largely composed of pyroxenite that is rich in sulfide minerals; to date it has supplied most of the world's platinum group metals, and also yields significant quantities of copper, nickel, cobalt and gold as byproducts. It is mined on both the eastern and western limbs of the Bushveld Complex: mineralised horizon

Platinum-group element (PGE) deposits in the Bushveld Complex and other layered intrusions form when large, incompletely solidified magma chambers undergo central subsidence in response to crustal loading, resulting in slumping of semi-consolidated cumulate slurries to the centres of the intrusions and hydrodynamic unmixing of the …

The layered mafic rocks of the Bushveld Complex are derived from three magmatic lineages - a lower part comprising the Lower and Critical Zones which crystallized from high-Mg and-Si parent liquids, an isotopically distinct Lower Main Zone derived from more evolved aluminous tholeiitic liquids, and a succession above the Pyroxenite Marker, …

Introduction. The Bushveld Complex (BC) is a large layered intrusion, emplaced into a stable cratonic setting. It has been considered an intrusive equivalent of a continental flood basalt province, and inferred to be related to a mantle plume (Hatton, 1995).The duration of continental flood basaltic magmatism may be of the order of …

The Merensky Reef (MR) of the Bushveld Complex is known for containing the lion's share of the world's reserves of platinum group elements (PGE). It is commonly described as a single, relatively thin layer (or package) of chromite- and sulphide-bearing orthopyroxenite hosted by almost barren norite and/or anorthosite. Here, we present a …
