Volcanic and hydrothermal reconstruction of the Pilley's Island volcanogenic massive sulfide district, central Newfoundland
Pilley's Island in the Central Mobile Belt, Newfoundland, Canada, is host to a cluster of bimodal felsic Zn-Pb-Cu-Au-Ag volcanogenic massive sulfide (VMS) deposits. In the Pilley's Island terrane, VMS-bearing felsic volcanic rocks are derived from the remelting of a hydrated, arc basalt su...
