Toward a multidisciplinary chronostratigraphic calibration of the Jurassic-Cretaceous transition in the Neuquén Basin

Detailed systematic studies have been carried out in the Vaca Muerta Formation in order to achieve an integrated multidisciplinary calibration of the Jurassic/Cretaceous transition in the Neuquén Basin. Although this unit has a very well-established ammonite biostratigraphy, the temporal distributio...
