Palinoestratigrafia do intervalo Alagoas da Bacia do Araripe, Nordeste do Brasil

Abstract: 42(2): 331-342, junho de 2012Arquivo digital disponível on-line no site www.sbgeo.org.br 331 ResumoO conhecimento da história geológica da Bacia do Araripe traz contribuição efetiva ao entendimento da dinâmica evolutiva da geologia do Nordeste brasileiro. Apesar das inúmeras pesquisas realizadas nessa bacia quanto a seu rico conteúdo fossilífero -em especial no intervalo Alagoas -, poucos são os estudos dedicados à sua bioestratigrafia, um aspecto essencial quando se deseja entender a história evolutiva de uma… Show more

“…These data reinforce the potential 51 , the first occurrence of Microhedbergella renilaevis marks an important bioevent that represents a major step in the evolution and diversification of the Albian planktic fauna, an event that was not identified in the studied section. Furthermore, the chronostratigraphic positioning of the lithological section studied in the upper Aptian, can be corroborated by the occurrence of Sergipea variverrucata Palynozone P-270 [66][67][68] , which was identified throughout the Sítio Sobradinho section by Teixeira et al 69 .…”

“…Due to the high preservation quality of several fossil groups, especially 3D-preserved fishes (Martill, 1988;Maldanis et al, 2016), scientific studies have focused mainly on the systematic paleontology. The chronostratigraphy is based on biostratigraphic schemes using palynomorphs (Regali, 1974;Lima, 1978;Coimbra et al, 2002;Rios-Netto et al, 2012). In contrast, there are far fewer studies dealing with the stratigraphy and sedimentology of the sedimentary package, and those related to facies analysis and sequence stratigraphy are scarce (Assine, 1992(Assine, , 2007Assine et al, 2014).…”

“…The stratigraphic assignment of the different units is essentially based on terrestrial palynomorphs and ostracods. For the concretion‐bearing Santana Formation, a latest Aptian to Early Albian age is suggested (Coimbra et al ., ; Heimhofer & Hochuli, ; Rios‐Netto et al ., ).…”
