SUMMARY: The revision of the geological mapping of the Caramulo-Destriz region allowed identifying the
succession constituted by the Beiras Group (Neoproterozoic), on which Armorican Quartzite Formation is settled in angular discordance. This last unit succeeds in concordance with the Brejo Fundeiro Formation
(Middle Ordovician) which has affinities with the sequence recognized in the Buçaco syncline and is in
continuity with the Arganil quartzites. A NW-SE synclinorium with NW vergence and axial plane schistosity,
associated with the main variscan phase, was also identified in the region. The outline of its axis presents
the configuration of a sigmoid that resulted from a right shear, sub-parallel to the Porto-Tomar-Ferreira do Alentejo Shear Zone.
