Paleocoordinates: | 7.7° North, 77.5° West |
Basis of coordinate: | estimated from map |
Geographic resolution: | outcrop |
Time
Period: | Paleogene | Epoch: | Oligocene |
Stage: | Chattian | 10 m.y. bin: | Cenozoic 4 |

Stratigraphy
Formation: | Caimito | Member: | Middle | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: From middle member. Three members of the Caimito Formation are recognized in the Gatun Lake area: lower, middle, and upper. The lower member is predominantly conglomerate and tuffaceous sandstone; the middle member consists of tuffaceous sandstone; the upper member comprises tuff and tuffaceous siltstone. The thickness of the Caimito Formation in the Gatun Lake area is around 300 m or more. Larger foraminifera support a late Oligocene age; corals favor a late Oligocene age, although early Miocene is unlikely; molluscs also confirm an Oligocene age. |
