| contents | Located at the northern tip of the Altiplano, the Abancay Deflection marks abruptly the latitudinal segmentation of the Central Andes spreading over the Altiplano to the south and the Eastern Cordillera northward. The striking morphological contrast between the low-relief Altiplano and the high-relief Eastern Cordillera makes this area a well-suited place to determine spatio-temporal variations in surface and/or rock uplift and discuss the latest phase of the formation of the Central Andes. We quantified exhumation and uplift patterns in the Abancay Deflection since 40 Ma, and present new apatite (U-Th)/He and fission-track data from four altitudinal profiles and additional individual samples (This dataset). Rock samples were collected in the whole Abancay Deflection area during a field campaign between april and july 2017. Analytical protocole for both dating method (AHe & AFT) was carried out during 2018 and 2019 at GEOPS laboratory (Université Paris Saclay, France) for AHe, and at ISTerre (GTC platform, Université Grenoble Alpes, France) for AFT dating. |
