Description
Lithologies
The La Naveta Formation is characterised by a lower part of
black shales intercalated.[1]
Stratigraphy and depositional environment
The La Naveta Formation overlies the Útica Formation and is overlain by the Trincheras Formation. The age has been estimated to be Hauterivian to Barremian. Stratigraphically, the formation is time equivalent with the Las Juntas, Ritoque and Paja Formations.[1]
Outcrops
The La Naveta Formation has its type locality to the north of the Bogotá River.[1]
