Stratigraphy

Stratigraphy comments: Marine strata of early Tertiary age in the Gatun Lake area are tentatively designated the marine member of the Bohio Formation. They are thought to represent a marine tongue in the lower part of what is essentially a non-marine formation. The age is disputed. Large foraminifera point to a late Eocene age and are unlikely to reworked, but large foraminifera of Oligocene age were undescribed from the Carribean at the time of writing. Mollusa have regional Eocene affinities, although others have later affinities. The most amrked faunal similariies are with the late Eocene of Columbia and the late Eocene-early Oligocene of Peru. A late Eocene-early Oligocene age was assigned to these collections. A literature search has failed to resolve this age any finer for this "tongue". |
Lithology and environment
Primary lithology: | concretionary,tuffaceous silty,calcareous sandstone |
Includes fossils? | Y |
Lithology description: Listed as "loose calcareous concretions at waters edge". Strata consist of dark tuffaceous silty sandstone, containing practically black calcareous concretions, and small-pebble conglomerate. Fossils were found in the calcareous concretions and also in the sandstone. A thickness of 95 feet (29 m) was reported for this section. | |
Environment: | coastal indet. |
Geology comments: A marine tongue within a overall non-marine lithostratigraphic unit. |
Taphonomy
Modes of preservation: | body,concretion |
