Ore Deposits and Mantle Plumes

  • 699 Accesses

Abstract

Erosion of continental flood basalts exposes the underlying feeder dykes and layered intrusions. Intracontinental layered intrusions, hosting magmatic ore deposits, have the closest link with mantle plumes. By far the best example of the great layered intrusions is the Bushveld Igneous Complex in South Africa, which is undoubtedly the largest repository of Cr, PGE and V in the world. In addition, this Complex contains large resources of other metals, such as Sn, Cu, Au, W, related to regional-scale hydrothermal ore systems powered by its magmatic heat. Layered intrusions, therefore, constitute an economically important class of magmatic bodies. For this reason, an understanding of the physico-chemical mechanisms that lead to layering and the precipitation of sulphides and oxides is of fundamental importance.
