“…In northeastern Brazil, there is evidence of 2 or 3 high sea level periods within the last 30 ma (Figure 1 and Figure 2) as previously discussed by Mörner et al [2] and by Rossetti et al [13]. At around the Oligocene/Miocene boundary, sea level was at least 40-50 m higher than at present and vast areas of southeastern Amazonia were inundated by the sea as evidenced by shallow marine and estuarine deposits of the Pirabas Formation [14]- [16] (Figure 2(a)).…”

“…Em sua porção oeste, a área de estudo é constituída por rochas gnáissicas e migmatíticas précambrianas (Figura 1B-C), que faz parte dos terrenos deformados da Província Estrutural Borborema (ALMEIDA et al, 2000;BRITO NEVES et al, 2009 ROSSETTI et al, 2013), foi primeiramente atribuída a ambientes essencialmente continentais dos tipos fl uvial entrelaçado e leques aluviais (ARAÚJO et al, 2006;MORAIS et al, 2006). Essa unidade foi reinterpretada como contendo depósitos formados em ambientes litorâneos infl uenciados por correntes de maré (ROSSETTI et al, 1990).…”

“…The formation comprises mainly of carbonates, intercalated with laminated siltstones, and, less commonly, fine-grained sandstones. The stratal architecture indicates an overall progradational pattern, but sedimentation was influenced by cyclical transgressive-regressive events that affected both lithology and biota (NOGUEIRA et al 2011, ROSSETTI et al 2013). …”

“…It contains a high number of taxa that represent mainly plants, microfossils, mollusks, echinoderms, bryozoans, fishes, crocodiles, and sirenians (see compilations of TÁVORA et al 2004, ROSSETTI & GOES 2004. The formation occurs on the northern and northeastern coast of Brazil (Pará, Maranhão and Piauí states), and is overlain by siliciclastic deposits of the Barreiras Formation (ROSSETTI et al 2013). The formation was deposited in environments typical of coastal deposits, such as shallow platform, tidal flat, lagoon and mangroves separated from the inner shelf by island barriers (FERREIRA 1977, GÓES et al 1990).…”
