Stratigraphy
| Geological group: | Limon | Formation: | Rio Banano | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The Rio Banano Formation sits diachronously with abrupt lithological transition on the Uscari Formation, mostly conformably and sometimes disconformably. The Rio Banano Formation passes conformably into the Quebrada Chocolate Formation in the area immediately west of Limon but throughout most of the southern Limon Basin it is unconformably overlain by the breccia and coarse grained volcaniclastics of the Suretka Formation. AGE: direct date extrapolated from Bybell (1999) and Collins et al. (1999). | |||||
Lithology and environment
| Primary lithology: | bioturbation,coarse,concretionary,tuffaceous sandstone |
| Secondary lithology: | burrows,tuffaceous silty siltstone |
| Includes fossils? | Y |
| Includes fossils? | Y |
| Lithology description: The sections at Quitaria and Bomba show two relatively thin, richly fossiliferous marine units with a thick deltaic section of burrow-mottled, coarse, tuffaceous, concretionary sandstone that frequently contains basalt pebbles, leaves, seeds and wood fragments. The lower marine section is exposed showing 15m of burrow-mottled, shelly clayey siltstone and silty, tuffaceous sanstone wiht frequent shelly stringers and lenses that contain an abundant and diverse marine mollusk and bryozoan assemblage. Thallasinoid burrow systems are common, often packed with shell hash, as are slabby and irregular concretion zones. | |
| Environment: | deltaic indet. |
| Geology comments: Thick deltaic succession. | |
