Sumario:New mapping of the pre-Ordovician basement (Schist and Greywacke Complex or Lower Alcudian) from the La Serena and La Siberia Extremeña regions of the southern Central Iberian zone has allowed the distinction of up to four independent stratigraphic units. The studied sequence is exposed in two megastructures: the Almorchón-Valdecaballeros Antiform and the Cerro de los Moros Synform, separated by the Patin Fault, which seems to correspond to an ancient paleogeographic boundary. The continuity of these structures under the Paleozoic synclines and the sub-orthogonal directions with respect to those of the Variscan cover is regarded as an evidence for deformational events related to the Cadomian (pan- African) cycle, likely in connection to those recorded in the adjacent Ossa-Morena Zone
