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.
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.
