Detailed geological mapping paired with meso to microstructural analyses pointed out the presence, in the Lodè-Mamone Ortogneiss Complex (Baronie, North-eastern Sardinia), of two folds systems developed during the third deformation phase overprinting older D2 antiforms and synforms. These systems of fold are characterized by axes trending respectively WNW-ESE and SW-NE and steeply dipping axial planes. As a result of this study, the structure, previously interpreted as a simpler second phase-related antiform, can be better explained as the result of interference pattern between the second and the third phase-related fold systems. Greater lithological complexity can be observed also in the acid orthoderivate complex, resulting from metamorphism on a series of Ordovician granitoid intrusions.
