The Dorsal de Cangucu Shear Zone (DCSZ) is part of a strike-slip fault system showing trends parallel to the Neoproterozoic Dom Feliciano Belt in southern Brazil. As an attempt to assess the role played by this fault system in the tectonic evolution

Structural mapping of key areas linked by reconnaissance investigations in the southern Brazilian portion of the Brasiliano/Pan-African Dom Feliciano Belt has shown the importance of large-scale flat-lying and strike-slip shear zones in the tectonic

Seismic wave propagation in organized matter usually results in azimuthal variations of longitudinal waves (Pwaves), as well as the effect of birefringence in transversal waves (S-waves), which results in two orthogonal shear waves with contrasting v
