| Resumo | The Borborema province, in northeast Brazil, consists of a complex set of crustal blocks of different ages, origin and evolution, with final amalgamation during the late Neoproterozoic Brasiliano orogeny. Its Central Domain is characterized by elongate NE-SW terranes largely affected by the Brasiliano metamorphic overprinting and by a suite of early Neoproterozoic metavolcanic rocks reflecting a distinct tectonic event (Cariris Velhos). Magnetotelluric (MT) data were collected at 64 stations along four profiles across this central region of the province to assess its deep electrical resistivity structure. Dimensionality analysis shows that the subsurface is electrically dominated by 3D structure, and 3D inversions of the full impedance tensor and vertical magnetic transfer function (tipper) were carried out. The dominant features in the final model are north-dipping crustal conductors, which can be correlated between the different MT profiles and cross contrasting terranes at the surface of the province. Considering the geometry and distribution of the conductors, they are interpreted as reflecting remnants of a pre-Neoproterozoic north-directed subduction zone with enhanced conductivity associated with graphitized biogenic material in metasedimentary rocks originally deposited in a restricted oceanic environment and subsequently metamorphosed and introduced into the deep crust by the subduction of the oceanic lithosphere. As the extent of crustal remobilization by the Brasiliano event seems to be restricted to the brittle upper crust, it is proposed that the Neoproterozoic geodynamic evolution in this domain of the Borborema Province occurred in an intracontinental setting. | |||
