Argon data for Southern Patagonian Andes

May 20, 2020

This dataset accompanies planned publication 'Detrital record of the Late Oligocene - Early Miocene mafic volcanic arc in the Southern Patagonian Andes (~51S) from single-clast geochronology and trace element geochemistry'. The Ar/Ar data is for samples that record the detrital sedimentary record of the basin. The geochronology provides time constraints for the sedimentation studied in the manuscript. Samples were collected from the Magallanes-Austral Basin, and collection was supervised by Julie Fosdick, who sent them to the USGS for Ar/Ar analysis.
