Rapid Formation of Porphyry and Skarn Copper-Gold Mineralization in a Postsubduction Environment: Re-Os and U-Pb Geochronology of the Ok Tedi Mine, Papua New Guinea
The Ok Tedi copper-gold mine in Western Province, Papua New Guinea, is situated in the western part of the Ok Tedi Complex where monzodiorite to quartz monzonite intrusions are associated with porphyry- and skarn-style copper-gold mineralization. The Pleistocene age of the intrusive rocks and mineralization provides an opportunity to study the longevity of the magmatic and hydrothermal evolution at Ok Tedi through U-Pb dating of zircon and high-precision Re-Os dating of molybdenite. Six main...[Show more]
