| Stratigraphy comments: Boule and Thevenin (1920) suggested a Pliocene age for the Tarija Formation. Nevertheless, MacFadden et al. (1983) provided a geochronologic study of the Tarija Formation in the Tarija basin using magnetostratigraphy and radioisotopic dating. They showed that this formation spans a time interval between 1.0 Ma and 0.7 Ma. | |||||
