Abstract: Structural analysis of the Itaja" Group has confirmed and increase in deformation magnitude from NW to SE, toward the more deformed zone of the Dom Feliciano mobile belt. This condition is in agreement with the predicted characteristics of a foreland basin deformed in a convergent environment. Two families of tectonic structures were recognized, both corresponding to different deformation phases and associated stress fields. The first represents the late collisional phase of the orogenic cycJe, which caused the development of reverse faults, asymmetric folds, and a conjuga te system of strike-slip faults. The progressive evolution of this convergence led to the change from a frontal to an oblique collision, with dextral-reverse kinematics. The second phase records a post-collisional extensional pulse, leading to the reactivation of earlier structures and inversion of movements along the conjugate system of strike-slip faults.
