                         structures of collisional orogens. Therefore, magnetotelluric and 
                         gravimetric data were combined in this study to enhance the poorly 
                         understood subsurface structure of the transition zone from the 
                         S{\~a}o Francisco Craton to the Neoproterozoic Sergipano Orogen 
                         in northeastern Brazil. The results along a 240-km-long, NESW 
                         trending geophysical transect revealed two main geoelectric 
                         domains beneath the Cretaceous Tucano Basin, which can be linked 
                         to two distinct tectonic blocks on the surface. The less resistive 
                         SW domain corresponds to the rocks of the Serrinha Block within 
                         the S{\~a}o Francisco Craton. In contrast, the more resistive NE 
                         domain matches the basement rocks of the northernmost units of the 
                         Sergipano Orogen. The results are discussed considering 
                         Paleoproterozoic and Neoproterozoic scenarios with different 
                         interpretations of the NE domain. Based on the surface geology and 
                         additional gravimetric and magnetotelluric data, the best scenario 
                         is to consider the NE domain as representing the geoelectric 
                         signature of the three northernmost geological domains of the 
                         Sergipano Orogen (Macurur{\'e}, Po{\c{c}}o RedondoMaranc{\'o}, 
                         and Canind{\'e}) and that of the PernambucoAlagoas Block (PEAL). 
                         PEAL collided with the S{\~a}o Francisco paleolithosphere forming 
                         the Sergipano Orogen. The NE geoelectric domain can be interpreted 
                         as an indenter of the tectonically intruded PEAL beneath the 
                         S{\~a}o Francisco paleolithosphere. The new data properly define 
                         the northern limit of the S{\~a}o Francisco Craton and explain 
                         both indentation structures and contrasting sediment provenance 
                         observed in the Sergipano Orogen.",
