Tectonomagmatic characteristics of the back‐arc portion of the Calama–Olacapato–El Toro Fault Zone, Central Andes

Post–20 Ma magmatism in the Central Andes is either localized in the magmatic arc or distributed east of it, on the Altiplano‐Puna Plateau. Here there is a distinct concentration of magmatic centers on NW–SE trending lineaments, such as the Calama–Olacapato–El Toro (COT), that extends into the Eastern Cordillera to the east of the Puna. Understanding the possible genetic relationship between prominent structures and magmatic centers on these …
