• Thermochronological data quantifying the tectonic history of the undocumented northern edge of the Peruvian Altiplano (Abancay Deflection) • 3-D thermo-kinematic models unravel the evolution of the Eastern Cordillera & the Altiplano • Steady and uniform exhumation between 40 and 5 Ma, followed by tectonicallydriven tilting of the Eastern Cordillera
