The middle Eocene Ainsa Basin, Spanish Pyrenees, comprises ~4 km of deepmarine sedimentary rocks belonging to the Hecho Group. Despite extensive study of these exemplary deep-marine clastic successions, there has been no comprehensive chronostratigraphic framework that provides primary ages for the submarine fan and related deposits. Here, we present a new composite basin stratigraphy based upon biostratigraphic analyses of the Upper Hecho Group submarine-fan and interfan deposits. Calcareous… CONTINUE READING
