The Morro del Cobre porphyry (Cu-Mo-Au) deposit, genetically linked to the upper Miocene magmatism (~9–10 Ma), is located at the eastern margin of the Andean Frontal Cordillera of San Juan, Argentina, over the Pampean flat-slab segment (28–33°S) of the Central Andes. The petrogenetic analysis of these rocks reveals an arc affinity and an adakite-like signature with the source magmas evolving under thickened crust conditions which resulted in a high pressure (amphibole ± garnet) residual mineralogy. These mineralizing magmas, that evolved towards shallower magma chambers (<10 km) have hydrous and oxidant character, typical of fertile suites worldwide. The emplacement of Morro del Cobre coincides with the passage of the aseismic Juan Fernandez Ridge as many other Miocene productive porphyry deposits in this segment of the Andes.

Morro del Cobre斑岩（Cu-Mo-Au）矿床，与上中新世岩浆作用（〜9-10 Ma）遗传相关，位于阿根廷圣胡安安第斯山脉科迪勒拉山脉的东缘，在Pampean平原上中部安第斯山脉的板块段（28-33°S）。这些岩石的岩石成因分析表明，其弧亲合力和类似于ad石的特征，其源岩浆在增厚的地壳条件下演化，从而导致高压（闪石±石榴石）残留矿物学。这些成矿作用的岩浆向浅岩浆室（<10 km）演化，具有含水和氧化特性，这是全世界肥沃的套房的典型特征。Morro del Cobre的进驻与抗震的Juan Fernandez Ridge的穿越相吻合，安第斯山脉的这一部分还有许多其他中新世生产的斑岩矿床。
