Barremian deposits of Colombia: A special emphasis on marine successions

By Pedro PATARROYO

Pages 237–254

Manuscript accepted February 14, 2019



Marine Barremian deposits are represented in different lithostratigraphic units in Colombia, from the central part of the country to the north. Up to the Upper Magdalena Valley, continental deposits have been reported in the Yaví Formation; although until now, only Aptian plant remains have been recognized.

Marine deposits include the shales and biomicrites of the Trincheras Formation to the west and southwest of Bogotá; the shales and biomicrites of the Fómeque Formation to the east and northeast of Bogotá; the biomicrites, biosparites, and shales of the Upper Calcareous Member of the Tibasosa Formation to the north of Bogotá; the shales and biomicrites of the Paja Formation near Villa de Leiva and to the northwest of Bogotá in the Middle Magdalena Valley; and in some cases, the biomicrites of the Rosablanca Formation.

The biomicrites of the Yuruma Formation occur in northern Colombia or the La Guajira area, near Venezuela; in the Cretácico del Río Cañas (La Guajira) deposits; and in the central and western regions of the Central Cordillera. Sporadic occurrences of Barremian ammonites have been reported but are poorly studied.

Other lithostratigraphic units that have been cited as being related to the Barremian deposits, albeit without biostratigraphic support, are the Tibú–Mercedes Formation and, possibly, the Río Negro Formation. Barremian ammonites have been reported in the La Naveta Formation but with controversial stratigraphic control.

Different fossil fauna and flora have been reported in these units, but ammonite biostratigraphy is the principal tool used to identify chronostratigraphic levels. Tethyan fauna allows one to correlate Barremian successions with standard biozones and horizons from the Mediterranean area, such as the Psilotissotia, Nicklesia, Pulchellia, Gerhardtia, Heinzia, etc.

The sedimentary and ecological variations in the lithological units are the consequence of environmental factors, paleoecology and basin differentiation that have recorded tectonic or subsidence influxes due to their local paleogeographic positions.

Keywords:Barremian deposits, biostratigraphy, lithostratigraphy, Colombia.
