What is PGE Ore Genesis and Enrichment Processes about?
1) Concentrations of platinum group elements (PGEs) can form through normal crystallization as incompatible elements build up in residual fluids, or through liquid immiscibility. 2) PGEs are commonly associated with chromite layers in ultramafic and mafic rocks, having accumulated in the residual fluids during crystallization of early minerals. 3) Two versions of PGE enrichment are proposed: ascending PGE-rich sulphide fluids enriching existing sulphide layers, or turbulent mixing of fresh magma with la
