The Chapada Cu–Au deposit, Mara Rosa magmatic arc, Central Brazil: Constraints on the metallogenesis of a Neoproterozoic large porphyry-type deposit

The large Chapada Cu–Au deposit is situated in Goiás Magmatic Arc, Central Brazil, which is part of an accretionary orogen with tectonic evolution between ca. 900 and 600 Ma during the Brasiliano Orogeny. With a current reserve (proven and probable) of 420.94 Mt Cu (0.29%) and 479.84 Mt Au (0.25 g/t) or 3.83 Moz Au, the Chapada Cu–Au deposit is an important example of a large-tonnage, low-grade porphyry copper–gold deposit of Precambrian age, in...
