Age, geochemistry, and fluid characteristics of the MAX porphyry Mo deposit, southeast British ColumbiaLawley, Christopher John Michael 11 1900 (has links)
MAX is a porphyry Mo deposit located near Trout Lake village in southeastern British Columbia. Mo mineralization is hosted by variably-altered calc-alkaline granodiorite dikes. Quartz veins have been subdivided into a paragenetic sequence based on vein style and crosscutting relationships. Post-magmatic Pb-Zn-Ag-bearing veins crosscut Mo-bearing veins. Similarities in fluid chemistry from both vein types suggest a genetic link between porphyry Mo mineralization and base-metal veins.
Three molybdenite samples were collected from early and late Mo-bearing veins for Re-Os dating to constrain the timing of Mo-mineralizing events within the paragenetic sequence. All three dates overlap within analytical error, and yield a weighted average age of 80.3 ± 0.2 Ma. These dates are in excellent agreement with two 206Pb/238U weighted-average ages of the Trout Lake stock at 80.2 ± 1.0 Ma and 80.9 ± 1.6 Ma, indicating that the magmatic and hydrothermal ore-forming events were coeval and cogenetic.
