Another goal of the BODES experiment was to build integrated geophysical images of the Borborema Province’s crust and lithospheric mantle in order to improve our understanding of its geodynamic and tectonic evolution. Conclusions: We have interpreted the high conductivities under the Araripe Basin as an indication of shallow, enriched asthenospheric mate- rial, involving small amounts of fluids and melt. We have proposed that the emplacement of a shallow asthenosphere would have orig- inated through extension and passive upwelling at the time of basin formation, and explained its preservation through geologic time by invoking lateral asthenospheric flow from a distant source. We have proposed that the hot, buoyant asthenospheric mate- rial under the basin provided a vertical push under the Araripe Basin that helped the tectonic inversion of the basin. Additionally, the presence of this asthenospheric material under the Araripe Basin – and the correspondingly raised geotherm – might have weakened the lithospheric mantle, caused regional compressional stresses to concentrate on the brittle crust, and contribute to basin uplift. The high resistivities flanking the conductive anomaly north and south of the Araripe Basin have been interpreted as thickened lithosphere representing lithospheric material that was eroded from under the basin and attached to the flanks through a roll-down flow process. Shear zones have been mapped as conductive anomalies cross- ing the crust in the Borborema region, suggesting the presence of conductive minerals or graphite, precipitated by fluids flow and shear zone reactivation. To the south of the profile, the Riacho do Pontal fold belt is observed to be flanked by conductive structures, which have been interpreted as relict subduction materialConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq): grant no 400743/ 2014-0 CNPq: visiting research fellowship held under the Ciência Sem Fronteiras program.
