DV 1611-1 [Chilcatay Fm] | DeVries T. J. (2007) | Chilcatay | STRATIGRAPHIC RELATIONS: From the Chilcatay Fm, which regionally, unconformably overlies the Otuma Fm (Oligocene) and is unconformably overlain by the Pisco Fm (Middle Miocene-Late Pliocene). AGE: latest Oligocene-early Middle Miocene, for which justification is not stated. Overlain by the Prisco Fm, for which K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy supports a Middle Miocene age at its oldest. The collection is placed by the authors within the Early Miocene. STR | sandstone | 23.03 - 15.97 Ma Miocene |
