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. Locality: Sabanita to Payardi. AGE: Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 11.3 Ma (Hendy, unpublished data).

Includes fossils?Y
Lithology description: GENERAL LITHOLOGY: The lower 5m of the lower Gatun Formation consists of volcanic conglomerate, with 1-5cm clasts and a tuffaceous, arkoskic matrix, cross-bedded, laminated, tuffaceous siltstone and alternating laminated sandstone and siltstone, mostly deeply weathered. The overlying 40m (Section 1) consists of massive, grey-green, clayey siltstone, with minor claystone and fine sandstone units. zones of densely packed large concretions, pervasive bioturbation, and extensive thalassinoid burrow systems, as well as simple vertical and lateral hash-filled burrows. Shell hash of varying grain size and density is almost ubiquitous, as are units packed with diverse, whole mollusks.
Environment:coastal indet.
Geology comments: ENVIRONMENT: from Collins et al. (1999), open, inner neritic.
