Time
Period: Neogene Epoch: Miocene
Stage: Tortonian 10 m.y. bin: Cenozoic 6

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. BIOSTRATIGRAPHY: The Middle Gatun Fm is early Late Miocene (8.8-8.3 MA) according to Collins et al. (1999). Local section name: Sabanita to Payardi. AGE: Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 10.9 Ma (Hendy, unpublished data).
Lithology and environment
Primary lithology:bioturbation unlithified siltstone
Secondary lithology:bioturbation unlithified siltstone
Includes fossils?Y
Includes fossils?Y
Lithology description: GENERAL LITHOLOGY: From Collins et al. (1999), the Middle Gatun Fm consists of alternating siltstone and sandstone with occasional 4-5 m units of interbedded sandstone and conglomerate. Pervasive bioturbation is extensive. LITHIFICATION: lithification data not reported, but assumed to be unlithified based on observation of specimens in Woodring (1957-1982).
Environment:coastal indet.
Geology comments: ENVIRONMENT: from Collins et al. (1999), open, inner neritic.
