The Utica sandstone (Berriasian), Murca Formation (Upper Valanginian), Cumbre Formation (Berriasian) and Rosablanca Formatlon (Valanginian) comprise the Lower Cretaceous sedimentary sequence In the central part of the Cordillera Oriental. This work presents a probable depositional setting for the Lower Cretaceous clastic and calcareous units. The Late Valanginian basin was divided into a central depocenter (Murca Formation), a southwestern shelf (Utica sandstone) and a northern platform (Cumbre and Rosablanca formations). The Cumbre and Rosablanca formations were deposited in shallow marine environments in the Tablazo-Magdalena basin, while the Utica sandstone and Murca Formation were deposited in shallow water and deeper water respectively by turbiditic currents. The sediments for the southern units came from the west, probably from the Paleo-Central Cordillera. The sediments for the northern units came from the Santander-Floresta paleomassif. The name Murca Formation is proposed for the turbiditic basal unit that crops out in the core of the Murca anticline, and a type locality is proposed.
