| Lithology description: Estratos de quebrada El Jote (Plioceno superior) Depósitos moderadamente consolidados,subhorizontales,que conforman secuencias de hasta 50m de espesor, depositados en forma concordante sobre gravas fluviales de la Formación Confluencia. Esta unidad se constituye de arenas, en parte coquináceas, limos, niveles de fangos calcáreos, además de intercalaciones de conglomerados de base acanalada. La mayor parte de la secuencia contiene restos fósiles, principalmente de gastrópodos y bivalvos marinos, además de cirripedios y en forma local de carófitas y vertebrados (mamíferos). | |
