Complexe igné du Bushveld — Wikipédia

Le complexe igné du Bushveld (CIB), en anglais Bushveld Igneous Complex, est une vaste intrusion magmatique stratifiée de la croûte terrestre.Elle s’est inclinée et a été érodée et, aujourd'hui, elle affleure au bord d'un bassin géologique, le bassin du Transvaal.Située dans le nord de l'Afrique du Sud, la formation contient quelques-uns des plus riches gisements minéraux de la ...

Bushveld - Wikipedia

The Bushveld is one of the most mineral-rich regions of the world. This is due to the Bushveld igneous complex, an extremely rich saucer-shaped geological formation that stretches over more than 50,000 square kilometers. This formation contains most of the world's reserves of minerals such as andalusite, chromium, fluorspar, platinum and vanadium. The complex includes the Merensky Reef, which is the world's biggest source of platinum as well as platinum-group metals.
