AB An Aptian rudist limestone unit, up to 200m thick and extending more than 3km, lies 2km to thesouth of Bilbao. The stratigraphy and mapping of the limestones in the Bolintxu valley reveal diachronouslower and upper boundaries grading laterally to sandy and marly facies respectively. A carbonate rampmodel with southeastwards backstepping in three pulses indicates a deepening upward trend. Depositionaldip of the ramp down to the west suggests westward tilting and development of enhanced subsident areasto the west. The orbitolinids indicate an Early Aptian (Late Bedoulian) age for the nuclear part of the ramp
