Abstract

Cenozoic sediments in southern Peru are responses of a complex interaction of active geodynamics and sedimentation, which is conspicuous of the Central Andes tectonics. By combining multimethodic analysis on single grain heavy minerals, it is possible to constraint uplift and exhumation history of the sedimentary basin borders in southern Peru and explain consistently sedimentation processes. The results reveal that Cenozoic sediments in southern Peru are coarse-grained deltas deposited since ~30 Ma as consequence of simultaneous uplift of the Coastal Cordillera and Western Cordillera.
