Gold and copper-gold mineralization in the Andahuaylas-Yauri Metallogenic Belt, Southern Peru

The geodynamic and metallogenic setting of Eocene-Oligocene ore deposits in southern Peru has been strongly influenced by the tectonic compression caused by the subduction of the Nazca-Farallon plate (Benavides-Cáceres, 1999; Somoza and Ghidella, 2012). During the Eocene, the subduction regime transitioned from moderately steep to shallow (Carlotto, 2013). Interaction between the oceanic plate with low subduction angle and the overriding continental crust produced widespread reverse faulting, intense folding, and rotation of crustal blocks (Benavides-Cáceres, 1999; Perelló et al., 2003; Arriagada et al., 2008; Roperch et al., 2011; Carlotto, 2013).
