Adakite-like signature in volcanic rocks associated with the Oro del sur Au - (Cu) epithermal deposit, Southern Precordillera, Argentina

The Oro del Sur deposit is located in the southern part of the Precordillera of Mendoza Province, Argentina (32°30'S, 69°05'W) within the flat-slab subduction segment. It is a Cu-(Mo) porphyry type system with associated high sulfidation Au-(Cu) epithermal veins genetically linked to Mioce...

It is a Cu-(Mo) porphyry type system with associated high sulfidation Au-(Cu) epithermal veins genetically linked to Miocene volcanic rocks which show geochemical characteristics (particularly low Y and low Yb values and high Sr/Y and La/Yb ratios) that indicate an adakite-like signature, and a Sr-Nd isotopic composition that suggests involvement of a depleted mantle source in their genesis.
