This study investigates the influence of the Romanche Fracture Zone on the tectono-sedimentary evolution of the Barreirinhas Basin, located in the central sector of the Brazilian Equatorial Margin and Guina. Based on integrated analysis of five seismic sections and three exploratory well, structures typical of transtensional environments were identified, including normal faults, listric faults, and negative flower structures, affecting both the basement and overlying sedimentary sequences. These features demonstrate strong tectonic control by the Romanche Fracture Zone over the morphology of the continental shelf, slope, and the internal compartmentalization of the rift and drift sequences. The evolution of the Barreirinhas Basin reflects a complex interaction between oblique rifting, strike-slip regimes, and later tectonic reactivations, classifying it as a pull-apart basin. The current configuration of the margin, marked by distinct structural segmentations, underscores the fundamental role of fracture zones in the genesis and development of basins along the Brazilian Equatorial Margin.
