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
Primary lithology: | lithified sandstone |
Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: Sandstone. LITHIFICATION: Lithified based on figured specimens. | |
Environment: | coastal indet. |
Geology comments: ENVIRONMENT: Not discussed in text, but appears to be from relatively shallow marine siliciclastic setting. High productivity, but also warmer than at the present day in the Peruvian upwelling zone. |
