Extremely negative and inhomogeneous sulphur isotope signatures in Cretaceous Chilean Manto-type Cu-(Ag) deposits, Coastal Range of central Chile.

Abstract

Chilean manto-type (CMT) Cu(–Ag) hydrothermal deposits share a characteristic association of volcano-sedimentary Jurassic to Lower Cretaceous host rocks, style of mineralization, ore and associated mineralogy and geochemistry, with ore grades typically >
