The Cenozoic exhumational evolution of the Southern Patagonian Andes and its potential tectonic and climatic controls remain poorly constrained. Here, we integrate 21 new and 73 published bedrock thermochronological ages with 3D thermo-kinematic modelling (Pecube) to quantify exhumation pulses in the Torres del Paine area. This approach is used to identify temporal and spatial variations in exhumation rates before and after the start of Late Miocene glaciation. Our new...
