Geochronological and thermochronological constraints on porphyry copper mineralization in the Domeyko alteration zone, northern Chile
(2010-01)
At Domeyko, 40 km south of Vallenar in northern Chile (28°57’S-70°53’W), the Dos Amigos and Tricolor
porphyry copper centers are located within a north-south-elongated hydrothermal alteration zone 6x1.5 km of surface
dimensions. ...
The Altar porphyry Cu-(Au-Mo) deposit (Argentina): A complex magmatic-hydrothermal system with evidence of recharge processes
(Society of Economic Geologists, 2014-05)
Altar (31° 29' S, 70° 28' W) is a large porphyry Cu-(Au-Mo) deposit with associated epithermal Au-(Ag- Cu) veins located in the Cordillera Principal of southwest San Juan province (Argentina). Altar is a complex ...
SHRIMP U-Pb dating of the Antucoya porphyry copper deposit: new evidence for an Early Cretaceous porphyry-related metallogenic epoch in the Coastal Cordillera of northern Chile
(SPRINGER, 2006-10)
The Antucoya porphyry copper deposit (300 Mt at 0.45% total Cu) is one of the largest deposits of a poorly known Early Cretaceous porphyry belt in the Coastal Cordillera of northern Chile. It is related to a succession of ...
Late Cretaceous porphyry copper mineralization in Sonora, Mexico: Implications for the evolution of the Southwest North America porphyry copper province
(2014)
Two porphyry Cu-Mo prospects in northern Sonora, Mexico (Fortuna del Cobre and Los Humos) located within the southwestern North American porphyry province have been dated in order to constrain the timing of crystallization ...
Geochronological and thermochronological constraints on porphyry copper mineralization in the Domeyko alteration zone, northern Chile

Trace metals in pyrite and marcasite from the Agua Rica porphyry-high sulfidation epithermal deposit, Catamarca, Argentina: textural features and metal zoning at the porphyry to epithermal transition
(2015)
Agua Rica is a world-class Cu (Mo–Au) deposit located in Catamarca, Argentina, in which the porphyry and high sulfidation epithermal stages are juxtaposed due to the telescoping of the mineralizing system. Pyrite is the ...
