Datos sobre los materiales del Cretáceo Terminal-Eoceno del sector del Alto Segura (Zona prebética occidental)

Abstract

This paper account for result of a first general view of the materials from the final Cretaceus to the Nummulitic, in the sud-east area of the high Course of the Segura river. 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.
