The hydrothermal evolution and genesis of the porgera gold deposit, Papua New Guinea

Description:
High grade gold mineralization at Porgera is the result of two spatially and temporally distinct mineralization events referred to as stages I and II. Stage I mineralization resulted in the formation of pyrite, Fe-rich sphalerite and galena rich vein sets, spatially associated with intrusions, and hosted in intrusions, the surrounding altered sediment and calcareous black shale. Early sulphide rich veins (A/B veins) contain several grams of Au/tonne but due to their scattered nature do not constitute high grade ore. The fluid responsible fo...
