Basal angular unconformity, inner disconformities, and the presence of dolos tones and ichnofossils suggesting the stratigraphic environment of these facies, are described. The paleogeograhic implications, as well as the magnitude of the intra-alcudian, sardic and taconic phases in this area are discussed. Finally the Upper Alcudian series are compared with known Upper Alcudian of neighbor areas.
