Location of the study area. (A) Palaeogeographical map of South America and Africa during the break-up of Gondwana by the late Aptian (~ 113 Ma) modified after the 115 Ma and 110 Ma plate tectonic reconstructions of Heine et al.28 with Africa fixed at present-day coordinates. Rigid lithospheric blocks are denoted by black labels: South African plate, BPB NE Brazilian Borborema Province plate, Jos Jos Plateau sub-plate, SLC Sao Luis Craton block. Actively extending basins are indicated by labels with a red background; post-rift basins are indicated by labels with a light grey background; the Araripe Basin is highlighted in the black box; abbreviations: CARS Central Africa Rift System, BeT Benue Trough, CdIGR Cote d’Ivoire/Ghana Ridge and associated marginal basins; DGB Deep Ghanian Basin, PotB Potiguar Basin, RTJ Recôncavo, Tucano and Jatobá Basins. Other abbreviations: RdJ Rio de Janeiro, B. basin, SPH São Paulo High. The A–A’ profile illustrates a longitudinal section extending from the equatorial region in the Central South Atlantic to the Southern South Atlantic, between which is the barrier of the São Paulo High comprising the Rio Grande Rise and the Walvis Ridge, after Carvalho et al.115. The global palaeogeographical sample map was obtained from Colorado Plateau Geosystems https://deeptimemaps.com/. (B) Geological map of the Araripe Basin created using ESRI ArcMap v.10.3 software (https://www.esri.com/en-us/arcgis/products/arcgis-pro/overview) with metadata acquired from the online Geosciences Service of the Geological Service of Brazil-CPRM. The complete figure was composed by Juliana Guzmán using CorelDRAW X7 software (https://www.coreldraw.com).
