Stratigraphy
| Formation: | Charco Azul | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: LITHOSTRATIGRAPHY: From Charco Azul Formation (Olsson 1942), which unconformably underlies the Armurelles Fm (Pleistocene). AGE: Pliocene in Olsson (1942) as it is overlain by very different Pleistocene fauna age; supported by other sources, including Collins and Coates (1999). Correlated to Jama and Canoa Formations of Ecuador. STRATIGRAPHIC POSITION: From unknown position within section. | |||||
