The study utilized rhenium-osmium age dating (Re-Os), a form of radiometric dating, of molybdenite from an outcrop sample.
Key Points:
- The study utilized rhenium-osmium age dating (Re-Os), a form of radiometric dating, of molybdenite from an outcrop sample.
- Attendant potassic alteration (Kspar/biotite) and quartz, magnetite, epidote, and native copper mineralogy (Afton, Kwanika) are also key components.
- The Re-Os date of (202.8 +/-0.8Ma) from molybdenite on the Gail rock sample is within the Late Triassic to Early Jurassic porphyry Cu-Au (-Mo) age of mineralization cluster of 215-205Ma observed within porphyries located throughout British Columbia.
- The dating procedure involved sampling areas with visible molybdenite followed by metal-free crushing, followed by gravity and magnetic concentration methods to obtain a molybdenite mineral separate.
