- •
Epithermal deposits are associated with basaltic to rhyolitic igneous rocks.
- •
Rock geochemistry is consistent with subduction-related arc and back-arc magmatism.
- •
Igneous rock petrogenesis involved open-system processes.
- •
Dominant Au and Ag productivity is restricted to felsic to intermediate magmas.
- •
Magmas with distinct compositions are not required for epithermal deposit formation.
