The Serravallian-Tortonian boundary in the lower Tagus Basin (Portugal) and the new GSSP of the Tortonian stage
| Resumo: | In the Lower Tagus Basin (Setúbal Peninsula, Portugal), biostratigraphic data as well as isotopic dating allowed an age of 11.6 Ma to be ascribed to the lower boundary of the local depositional sequence T1 (Antunes et al., 2000; Legoinha, 2001). Hilgen et al. (2005) announced the new GSSP of the Tortonian Stage at Monte dei Corvi (Italy) and presented the various stratigraphic tools available for global correlation. In this paper, two outcrops concerning this boundary are presented and correlated with the new GSSP of the Tortonian Stage, astronomically dated at 11.608 Ma. |
