Stratigraphy
| Formation: | Pisco | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Pisco Fm, which regionally, unconformably overlies the Chilcatay Fm (late Oligocene-early Middle Miocene). AGE: Early Pliocene in text, on the basis of K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy.
