RHENIUM DISTRIBUTION IN MOLYBDENITE FROM THE VOSNESENSK PORPHYRY Cu (Mo,Au) DEPOSIT (SOUTHERN URALS, RUSSIA)

Molybdenite from the Voznesensk porphyry Cu ± (Mo,Au) deposit, southern Urals, Russia, displays high Re content and a well-documented oscillatory zoning for this mineral. The molybdenite forms part of a quartz-molybdenite-pyrite-chalcopyrite assemblage cemented at low-temperatures by pumpellyite and tobermorite. Oscillatory zoning occurs as micro-bands up to 200 μm wide and 200–600 μm long oriented parallel to the basal cleavage, as well as...
