U-Pb detrital zircon ages of upper jurassic continental successions: Implications for the provenance and absolute age of the jurassic-cretaceous boundary in the Neuquén Basin

Mostrar todas las versiones(2)

New U-Pb detrital zircon ages are presented for the Tordillo Formation. The ages indicate that the most important source region of sediment supply was the Jurassic Andean arc (peaks at c. 144, 153 and 178 Ma), although two secondary sources were defined at c. 218 and 275 Ma. Temporal variation in th...
