Filling the gap: New precise Early Cretaceous radioisotopic ages from the Andes
Two tuffs in the Lower Cretaceous Agrio Formation, Neuquén Basin, provided U-Pb zircon radioisotopic ages of 129.09±0.16 Ma and 127.42±0.15 Ma. Both horizons are well constrained biostratigraphically by ammonites and nannofossils and can be correlated with the 'standard' sequence of the Me...
