In the North Western sector of the Alps an intense brittle tectonics overprints the nappe stack and related ductile deformations. On a regional scale, different brittle structural sets can be identified. The main purpose of this work was to test the reliability of optical and SAR data to identify new lineaments and to test their mutual interference in a collisional orogenic belt. ERS-1 Geocoded Terrain Correct data, provided by the Italian Processing and Archiving Facility (I-PAF) were analyzed and compared with optical data. These products were verified to be essentially complementary by geological interpretation. As an integrate result, the lineament length and orientation fit well the kinematic model of the study area, obtained through field analysis and apatite fission track datations (AFT) on differential uplift. Moreover it was also identified a close relationship between lineament sets and deep-seated gravitational slope deformations.
