- Abstract:
- We aim to provide a well-constrained evaluation of the extent of Platinum Group Elements (PGE) recycling and fractionation in the subduction zone environment and the implications for these fractionations for the source of copper-gold mineralisation in arcs via the analysis of combined PGE and Re-Os isotopes on primitive basaltic magmas from a unique DSDP drill-core sample suite from the Philippine Sea Plate. Previous geochemical studies show that the lavas share a common upper mantle source that has been variably affected by subduction zone and plume components. Therefore, these lavas will provide (1) an ideal means of examining the relationship between tectonics and PGE chemistry, (2) new perspectives on the PGE flux recycled into the source of subduction zone and plume lavas, and (3) evaluate the implications for mineralisation of Cu and Au.
