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 Middle Miocene to Late Pliocene on the basis of K/Ar dates, siliceous microfossil zonation, and molluscan biostratigraphy supports. Stated in text to be of Middle Miocene age. STRATIGRAPHIC POSITION: From unknown position within section. | |||||
Lithology and environment
