This review explores the complex interactions of endogenic and exogenic processes in the segment of the Andes that straddle a transition from flat slab to normal subduction (32°-36°S). This segment shows remarkable along-strike variations in topographic uplift, structural elevation, amount and rate of shortening, and crustal root geometry. In the flat-slab segment, high elevations, several tectonic provinces and the lack of active volcanism characterize the orogen. Deformation and uplift advanced to the east, together with arc-related magmatic activity, sequentially uplifting the Principal Cordillera (20 to ~8 Ma), the Frontal Cordillera (12 to 5 Ma), the Precordillera (
