A new tectonic subdivision of the central External Betic Cordillera is proposed based on previous stratigraphic studies, interpretation of seismic reflection profiles and balanced cross-sections. All available surface and subsurface data are used to constrain a balanced cross-section in the central part of the Betic folded belt, and reconstructions are presented to illustrate three optional evolutionary sequences for this folded belt. In the favored option, the outermost allochthonous unit is interpreted to be bounded to the south by a backthrust. In the reconstruction this unit is located immediately south of the undeformed foreland. Furthermore, the dominant structure in the main part of the folded belt is postulated to be a large, elongate klippe emplaced by a north-directed overthrust. Based upon stratigraphic correlations across and along the thrust belt, the paleogeography that results from this structural reconstruction is that of a single basin.
