| Key time interval: | Aquitanian |
| Age range of interval: | 23.04 - 20.45 m.y. ago |
| Age estimate: | 21.0 ± 0.6 to 19.7 ± 0.5 Ma (K-Ar) |
| Formation: | Biblian |
| Stratigraphy comments: Bristow (1973) and Bristow and Parodiz (1982) described andesitic lavas at or near the contact between the Biblian Formation and the overlying Loyola formation, and reported two K-Ar whole rock determinations of 19.7 +/-0.5 and 21.0 +/- 0.6 Ma for one of this lavas outcropping near Descanso on the east side of the CUenca Basin. The Descanso andesite is consider to correspond to the upppermost Biblian formations. |
