Detrital zircon U-Pb geochronology of the Magallanes-Austral Basin, Australia
In this dataset we present detrital zircon U-Pb geochronology from the Magallanes-Austral retroarc foreland basin of Chile and Argentina (51°30’S). Detrital zircon U-Pb geochronology data show mostly Neogene (~20-40 Ma) and Cretaceous (~70-110 Ma) age groups, with minor amounts of Jurassic (~145-155 Ma) and Paleozoic (~260-540 Ma) zircons that are consistent with a syndepositional arc and recycled external-fold-and thrust belt sources.
