Low-temperature Thermochronology data from Patagonia

This is the apatite and zircon (U-Th)/He dataset from the Fitz Roy and Torres del Paine massifs in Southern Patagonia that supports the study in revision: “Geodynamic and climatic forcing on late-Cenozoic exhumation of the Southern Patagonian Andes (Fitz Roy and Torres del Paine massifs)” by Muller, V.A.P. et al., 2023 (preprint DOI: 10.22541/essoar.168332179.93378898/v1).

Apatite (U-Th/He) thermochronometry was performed following standard procedures (House et al., 2000) at the ARHDL of University of Arizona (USA) for plutonic samples of Torres del Paine, and at the Berkeley Geochronology Center (USA) for metasedimentary samples of Torres del Paine. Apatite (U-Th/He) thermochronometry of Fitz Roy plutonic samples was performed in the GEOPS Laboratory at the Paris-Saclay University (Orsay, France), following the methods of Gautheron et al., (2021). Zircon (U-Th/He) thermochronometry of Fitz Roy plutonic samples was performed in the UTHHE Laboratory of Dalhousie University (Halifax, Canada) following the methods of Reiners et al. (2004, 2005).
