Paleogeographic, structural and magmatic evidences for the existence of different lithospheric blocks in the Central Andes: Samples from southern Peru and northern Chile

Abstract:

The Andes are classically considered to represent the type of orogenic chains resulting from the subduction of an oceanic plate beneath a continental plate. In spite of a considerable literature involving stratigraphic, paleogeographic, structural, magmatic and geophysical data, any model that convincingly explains the modality of the Andean surrection has been emerged. All the current models focused on the importance of the subducting plate and very few considerations on the heterogeneity of continental plate. Paleogeographic reconstructions, structural evidences and magmatic and metallogenic evolution of Southern Peruvian Western Cordillera and Northern Chilean Domeyko Cordillera are used to identify a structure that delineates two different lithospheric blocks.
