El Pilar: A Particular Case in the Porphyry Copper Deposits in Mexico
El Pilar is a porphyry copper deposit located in the northern part of the state of Sonora, Mexico, at ~15 km from the border with USA, and about (40 km) from the town of Cananea, inside the most favorable part of the porphyry copper belt of the southwestern North America. Its features are relatively...

El Pilar es un yacimiento de tipo pórfido de cobre ubicado en el estado de Sonora, México, a 15 km de la frontera con E.U.A., y 40 km de la ciudad de Cananea, dentro de la zona más favorable del cinturón de pórfidos de cobre del suroeste de Norteamérica. Sus características son relativamente atípicas en comparación con el resto de los depósitos en México, considerando el modelo más aceptado de un pórfido de cobre. El Pilar es un yacimiento de cobre exótico hospedado en gravas del Mioceno, que rellenaron cuencas generadas durante el evento extensional Basin and Range. La mineralización de sulfuros hipogéncos aflora poco y está asociada con una brecha magmática ligada al emplazamiento de un plutón monzonítico fechado por U-Pb en zircones en ~75 Ma. La edad del depósito obtenida por Re-Os en molibdenita es de ~73.9 Ma, y las reservas se estiman en 0.36 Mt de cobre.
