• Resumen

  • Facies analysis and distribution in the Karrantza and Trucfos Valleys have allowed a detailed correlation of Upper Albian series. A new carbonate platform belonging to the Urgonian Complex is described and correlated with siliciclastic platform sequences of Upper Albian (Hysteroceratian) age. The stationary platform margin shows no signs of steep slopes and was surrounded by a shallow basin dominated by siliciclastics derived from a broad deltaic system
