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...
