The Senonian presents southwards a more open-sea facies character. The Paleocene shows pararecifal facies. The passage from Cretaceous to Paleocene is represented by a lithological change or, at least, a change in the deposition conditions, without evidences for the presence of an unconformity. The Eocene has very homogeneous facies belonging to a shallow-water environment. The thickness seems to increase southerly.spajournal articleopen accessGeología estratigráfica2506.19 Estratigrafía
