Hydrothermal alteration and lithogeochemistry of the boundary volcanogenic massive sulfide (VMS) deposit, Central Newfoundland, Canada
The Boundary volcanogenic massive sulfide (VMS) deposit (0.45 Mt @ 3.4% Cu, 4.0% Zn, 1.0 % Pb, 34 g/t Ag) is located in the Tally Pond group (~510 Ma), central Newfoundland, Canada. The deposit is hosted by rhyolitic rocks that are interpreted to have formed within a rifted continental arc on the le...
