The Middle Cretaceous in the Iberian Ranges is a 2nd order cycle with an Upper Albian - Middle Turonian age. The cycle is bounded by two major unconformities and comprise 8 depositional sequences (3rd orderI The four basal sequences onlap older deposits; maximum marine facies are located in the fifth sequence (Picofrentes Marls) and the upper three sequences offlap rapidly northwestwards. Along this time there was a northwestward shifts in the basin and Tethyan transgressions (Upper Albian - Middle Cenomanian) change to Atlantic ones (uppermost Cenomanian - Middle Turonian)
