“…The paleogeographic reconstruction of the Alagoas stage is controversial, having proposals of meanings of marine ingression from the Sergipe-Alagoas , Recôncavo-Tucano-Jatobá Basin and also from the Parnaíba Basin (Assine, 2007). A recent work by Souza et al (2022), through U-PB analysis in dendritic zirconium elaborated a model of paleogeographic reconstruction for the Mesozoic of the Araripe Basin and claimed that the main route of connection between the basin and the opening of the South Atlantic Ocean during the Jurassic period until the middle of the Cretaceous was through the Potiguar Basin. This conclusion differs from previous models that postulate this maritime route from the northwest or the south.…”

Several Phanerozoic sedimentary basins developed over the rocks of Borborema Province. The formation and opening of the Atlantic Ocean influenced tectonic events that reactivated large internal lineaments of the province (Transbrasiliano, Senator Pompeu, Patos and Pernambuco) culminating with several structures among them the grabens where the sediments of the intra-continental basins were deposited. This deformation played a fundamental role in the development of the continental margin basins that form the WNW-ESE and N-S segments of the Brazilian northeast. This work addresses the terrestrial portion of the Mesozoic basins inserted in the context of the Borborema Province and aims to provide a lithostratigraphic review plus some unpublished data of the inner basins and the Jatobá Basin. The descriptions of the marginal basins were subdivided by the following structural domains: dextral equatorial, orthogonal and sinistral south branching. The Ceará and Potiguar basins are part of the equatorial margin. The orthogonal domain encompasses the Pernambuco and Paraibá basins and is composed of the crustal block equivalent to the cross-sectional area of the Borborema Province, limited by the Pernambuco and Patos lineaments. The Sergipe-Alagoas basins are located in the sinistral branching. The intra-continental basins are equivalent to the failed rift arms that are composed of aborted rifts and semi-grabens of the inner basins of northeastern Brazil. The Recôncavo-Tucano-Jatobá rift system that was aborted still in the Lower Cretaceous is represented in the Borborema Province area by the Northern Tucano and Jatobá basins. The inner basins are concentrated in the region of the cross-sectional area, however, to the north of the Patos Lineament important basins occur such as Iguatu and Rio do Peixe. The basins of the orthogonal domain correspond to the final stretch of rift, being a late rupture in Aptian due to the rigidity of the basement. Due to the potential of oil exploration, the marginal basins are the ones that present data available in the literature the most. Both marginal basins with lower oil potential (such as the Pernambuco and Paraibá basins) and the inland basins of the northeast, covering the Jatobá, need more consistent lithostratigraphic update to consolidate and validate new proposed units.

“…The distribution of these marine organisms, many related to the Tethyan Realm, suggests short marine incursions from the Central Atlantic Ocean (e.g. 7 , 20 , 32 , 33 ), which could have occurred due to sufficient tectonic subsidence rates, accompanied by sea level rise episodes 9 , 34 at different times during the Early Cretaceous.…”

“…Reversal-related magnetic anomalies indicate that onset of the opening occurred around Anomaly M13 (134 Ma 5 ) in the Austral Atlantic Ocean, but the Cretaceous Normal Polarity Superchron (C34n; 121 to 83.65 Ma 6 ) complicates age determination for its subsequent spread northwards, between the Barremian and Aptian interval.Identification of the source and pathways taken by the first marine flooding episodes from the South Atlantic Ocean into the Brazilian intracratonic sedimentary basins is further complicated by conflicting results based on paleontological and sedimentary proxies (e.g. [7][8][9] ). Paleontological data supports a clear connection with Tethyan sea waters (e.g.…”

This study reports a set of primeval marine incursions identified in two drill cores, 1PS-06-CE, and 1PS-10-CE, which recovered the Barbalha Formation, Araripe Basin, Brazil. Based on a multi-proxy approach involving stratigraphy, microbiofacies, ichnofossils, and microfossils, three short-lived marine incursions were identified, designated Araripe Marine Incursions (AMI) 1–3. AMI-1 and AMI-2, which occur within the shales of the Batateira Beds (lower part of the Barbalha Formation), were identified by the occurrence of benthonic foraminifera, calcareous nannofossils, dinocysts, and a mass mortality event of non-marine ostracods. AMI-3 was recognized in the upper part of the Barbalha Formation, based on the occurrence of ichnofossils and planktonic foraminifera. The observation of the planktonic foraminifera genus Leupoldina for the first time in the basin indicates early Aptian/early late Aptian age for these deposits, and the first opportunity of correlation with global foraminifera biozonation. Our findings have implications for the breakup of the Gondwana Supercontinent, as these incursions represent the earliest marine-derived flooding events in the inland basins of northeastern Brazil.

Early Cretaceous (Aptian to Albian) vegetation and climate change in Central Africa: Novel palynological evidence from the Doseo Basin

With the break‐up of the continents of Africa and South America and the gradual opening of the Atlantic Ocean in the late Aptian to early Albian, the global palaeoclimate and palaeogeographical patterns changed greatly. Whether and when a humid belt prevailed in the palaeoequator region during this period has been argued for a long time. The Doseo Basin, located in the Central African Rift system, is important for understanding the palaeoclimate of Central Africa during the Early Cretaceous. Here, a systematic palynological analysis of boreholes K‐1 and KE‐101 in the Doseo Basin was conducted to reconstruct the vegetation and climate change during the middle Aptian to early Albian in Central Africa. Relatively abundant fossil palynomorphs were obtained, and 76 species belonging to 67 genera were identified. Gymnosperms were found to be dominant in the palynoassemblage of boreholes K‐1 and KE‐101, and Classopollis was the most abundant in this group. Among fern spores, the ribbed spores accounted for a high proportion. Additionally, a small amount of angiosperm pollen grains was also found. Based on the characteristics of the palynomorphs, two assemblages were identified, probably spanning from middle Aptian–early Albian. The characteristics of the spore and pollen fossils, especially the decrease of Classopollis in boreholes K‐1 and KE‐101, suggest an obvious change in climate, from relatively arid to humid during the late Aptian to early Albian (within the interval 2215–2220 m of borehole K‐1). The climate change reflected by the palynological spectra in the Doseo Basin from dry to wet is consistent with that of the results from South America. This study further proves that the climate near the equator in the southern hemisphere began to change from the earlier relative drought to humid conditions with the gradual opening of the Atlantic Ocean during late Aptian to early Albian, and a humid climate zone was distributed from east to west in the equatorial region of the southern hemisphere.
