Recycled volatiles determine fertility of porphyry deposits in collisional settings

Why large porphyry Cu deposits like high Sr/Y magmas?

Porphyry systems supply most copper and significant gold to our economy. Recent studies indicate that they are frequently associated with high Sr/Y magmatic rocks, but the meaning of this association remains elusive. Understanding the association between high Sr/Y magmatic rocks and porphyry-type deposits is essential to develop genetic models that can be used for exploration purposes. Here we ...

Gold Distribution in Porphyry Copper Deposits of Kerman Region, Southeastern Iran

Porphyry Cu-Au Deposits of the Iron Mask Batholith, Southeastern British Columbia

The Iron Mask batholith is lo cated 10 km south west of Kamloops (Fig. 1). It is the source of Cu-Au-Ag pro duced from por phyry de pos its such as Afton, Cres cent, Pothook, Ajax West and Ajax East, as well as struc tur ally con trolled Cu-mag ne tite veins (Iron Mask, Makaoo, Grey Mask). Cur rently, it is the tar get of ex plo ra tion for Cu-Au-Ag-Pd min er al iza tion by DRC Re sources at th...

Late Cretaceous Volcanoplutonic Arcs in Northwestern British Columbia: Implications for Porphyry and Epithermal Deposits

Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...
