A general scheme for telluride deposition via gas condensation is attractive to explain features of mineralising systems that experienced sustained boiling, but tectonically-driven hydrothermal systems could be as efficient in making a Au-telluride deposit.
By emphasizing this distinction, the genetic links between Bi-tellurides and Au are recognised to be as important as those between Au-tellurides and gold in deposit formation. A general scheme for telluride deposition via gas condensation is attractive to explain features of mineralising systems that experienced sustained boiling, but ...
