Re-Os Geochronologic Data for Porphyry Deposits in the Yukon-Tanana Upland, Eastern Alaska
Rhenium-osmium (Re-Os) geochronology of molybdenite provides a tool to directly date mineralizing events in hydrothermal systems. In the Yukon-Tanana upland of eastern Alaska, numerous molybdenite-bearing porphyry occurrences are recognized. The deposits are related to middle and Late Cretaceous gra...
