| Coordinates: | 9.4° North, 79.8° West (view map) |
| Paleocoordinates: | 9.1° North, 78.5° West |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | small collection |
Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Tortonian | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Tortonian | ||
| Age range of interval: | 11.63000 - 7.24600 m.y. ago | ||
| Age estimate: | 10.9 Ma (other) |
Stratigraphy
| Formation: | Gatun | Member: | lower Gatun | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: The Gatun Fm rests unconformably on formations of different ages in different parts of the Panama Canal Basin. To the east of Colon, the Gatun Fm rests nonconformably on unamed Cretaceous volcanics. To the west of Colon, including several islands in Lake Gatun, the Gatun Fm rests with angular unconformity on the upper Oligocene Caimito Fm. AGE: Late Miocene, on the basis of microfossil biostratigraphy (see Collins and Coates, 1999), refined by enterer to Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 10.9 Ma (Hendy, unpublished data). | |||||
