Abstract

The 160 km-long Maranon Valley Au belt, located in the Eastern Andean Cordillera of Peru, represents a continental arc-derived igneous belt that formed along the Peruvian margin of Gondwana in the Early to Middle Mississippian. This multi-disciplinary and multi-scale approach ranging from micro textures up to important crustal contamination and responsible for the regional metal fertility, regional magmatic patterns reveals two main prerequisites for gold
mineralization including : (1) a long lived magmatic activity characterized by and (2) a transition from compressional to extensional regime acting as a trigger for gold mineralization. Additionally, this study reports for the first time the presence of invisible gold in the Pataz-Parcoy district and emphasizes the potentially refractory nature of the batholith-hosted, sulfide-rich gold mineralization.
