Abstract:

Active continental margins are shaped by subduction-related magmatism, and the Central Andes of South America are a prime example. The Central Andean orogen has evolved over the past 25 My via magmas ascending from the mantle and interacting with increasingly thickened continental crust. This process is reflected in the volumes and compositional variations of the magmas that erupt at the surface. These compositional variations can be traced in time and space, and, herein, we provide explanations for their cause and explore the nature of the Central Andes transcrustal magma systems that feed the iconic stratovolcanoes today.
