“…Phanerozoic basins are present in the southern and eastern parts of the country (Figure ). These basins are mainly Karoo sequences which reach a thickness of up to 3 km [ Wopfner , ; Linol et al ., ]. The term Karoo in the region has been used to refer to late Carboniferous‐Jurassic depositional sequences, which represent a regional erosional event that was associated with Gondwana tectonics [ Linol et al ., ].…”

The term Karoo in the region has been used to refer to late Carboniferous‐Jurassic depositional sequences, which represent a regional erosional event that was associated with Gondwana tectonics [ Linol et al ., ]. The rift flanks of the EARS form topographic highs along the western, northern, and northeastern margins of the craton (Figure bottom) and the eastern branch of the rift have divided the cratonic margins since ~ 25–30 Ma [e.g., Chorowicz , ; Wichura et al ., ].…”

From source to sink in central Gondwana: Exhumation of the Precambrian basement rocks of Tanzania and sediment accumulation in the adjacent Congo basin

Apatite fission track (AFT) and (U‐Th)/He (AHe) thermochronometry data are reported and used to unravel the exhumation history of crystalline basement rocks from the elevated (>1000 m above sea level) but low‐relief Tanzanian Craton. Coeval episodes of sedimentation documented within adjacent Paleozoic to Mesozoic basins of southern Tanzania and the Congo basin of the Democratic Republic of Congo indicate that most of the cooling in the basement rocks in Tanzania was linked to erosion. Basement samples were from an exploration borehole located within the craton and up to 2200 m below surface. Surface samples were also analyzed. AFT dates range between 317 ± 33 Ma and 188 ± 44 Ma. Alpha (Ft)‐corrected AHe dates are between 433 ± 24 Ma and 154 ± 20 Ma. Modeling of the data reveals two important periods of cooling within the craton: one during the Carboniferous‐Triassic (340–220 Ma) and a later, less well constrained episode, during the late Cretaceous. The later exhumation is well detected proximal to the East African Rift (70 Ma). Thermal histories combined with the estimated geothermal gradient of 9°C/km constrained by the AFT and AHe data from the craton and a mean surface temperature of 20°C indicate removal of up to 9 ± 2 km of overburden since the end of Paleozoic. The correlation of erosion of the craton and sedimentation and subsidence within the Congo basin in the Paleozoic may indicate regional flexural geodynamics of the lithosphere due to lithosphere buckling induced by far‐field compressional tectonic processes and thereafter through deep mantle upwelling and epeirogeny tectonic processes.

“…The Silurian-to-Jurassic-aged Parnaíba Basin is an intracratonic crustal sag that affected some 600.000 km 2 of north-central Gondwana, the cause of which is uncertain but likely linked to thermally-induced downwarping (Daly et al, 2014). During the Permian, when the Pedra de Fogo Formation was deposited, the basin was situated within the southern tropics (Linol et al, 2016) under a warm semi-arid climate that became increasingly dry in the Triassic (Iannuzzi et al, 2018).…”

The Pedra de Fogo Formation in the Parnaíba Basin of northeastern Brazil hosts a recently discovered lacustrine fauna and provides the only known record of the Captorhinidae in South America. Here, new captorhinid remains from this unit are described. Two partial mandibles, including one formerly ascribed to the genus Captorhinus, are here referred to Captorhinikos sp. a genus previously described from North America. The natural mould of a large mandible probably represents a new taxon within the captorhinid subclade Moradisaurinae, and a small skull roof is regarded as Captorhinidae indet. Captorhinids are generally considered to have been herbivores or omnivores. The Pedra de Fogo captorhinids likely played an important ecological role as primary consumers in the palaeoenvironment of this geological unit, which is also known for its extensive record of petrified forests. The new finds reinforce the close relationships between the continental faunas of palaeotropical western Gondwana and palaeoequatorial North America during the Cisuralian.

“…The first super sequence is Silurian in age, represented by the Serra Grande Group, which includes the Ipu, tianguá and Jaicós formations. It is followed by the mid Devonian-Lower Carboniferous Canindé Group (Itaim, Pimenteiras, Cabeças, Longá and Poti formations), Lower Carboniferous-Lower triassic Balsas Group (Piauí, Pedra de Fogo, Motuca and Sambaíba formations), Jurassic Pastos Bons Formation, and the Cretaceous units defined as the Corda, Grajaú, Codó and Itapecuru formations (Góes and Feijó 1994, Linol et al 2016.…”

“…the basic igneous rocks occur mostly as intrusions within the layers, while extrusions are restricted. the ages of basic magmatism ranges between 215 and 87 Ma, grouped into two formations: the Lower Jurassic Mosquito Formation in the center-west, and the Cretaceous Sardinha Formation in the center-east and northeast (Góes and Feijó 1994, Linol et al 2016) ( Figure 1).…”

This study defines the neostratotype of the Lower-Middle Albian Itapecuru Formation in the Parnaíba Basin, Northeast Brazil. In this sedimentary succession along the right bank of the Itapecuru river near the Itapecuru-Mirim City, Maranhão State, three lithofacies associations are recognized. the first is silty claystone with some very fine sand, micaceous, reddish color, thin laminated, showing a tabular aspect, interpreted as floodplain fines in a distal position. The second is clayey siltstone, reddish color, with ripple cross-lamination, very thin cross-laminated wacke lenses, grading to thin parallel lamination, in apparently tabular layers, interpreted as crevasse splay and distributive channels deposits in successive avulsion events. The third is fine quartz wacke, reddish to grayish color, showing grouped trough cross bedding, interpreted as channel filling deposits. These facies associations correspond to part of a fluvial depositional system, with predominantly fine-grained rocks, and small lakes in the floodplain, in an oxidizing environment and marked by seasonality. These field data, reinforced by grain size and petrographic analyses showed that, contrary to previous descriptions, the Itapecuru Formation consists mainly of mudrocks. this research also shows that the medium to coarse sandstones and conglomerates, previously included in the Itapecuru Formation, belong to the underlying Grajaú Formation.
