Hydrothermal reconstruction and lithogeochemistry of the Argyle orogenic gold deposit, Baie Verte, Newfoundland
The Argyle orogenic gold deposit (543,000 t @2.19 g/t Au indicated, and 517,000 t @1.82 g/t Au inferred resources) is located within Lower Ordovician Snooks Arm Group, Baie Verte Peninsula, Newfoundland. Gold mineralization is hosted as inclusions in secondary pyrite and at pyrite crystal boundaries...
