Syngenetic and diagenetic features of evaporite-lutite successions of the Ipubi...
Nascimento Junior, Daniel Rodrigues do; Silva Filho, Wellington Ferreira da; Freire Junior, José Gervásio; Santos, Felipe Holanda dosThe Ipubi Formation in the Araripe Basin (Northeast Brazil) has evaporite-lutite successions rich in gypsum, a mineral of great regional economic relevance, a highlighted stratigraphic mark, and also a natural boundary for underlying successions potentially analogous to “Pre-Salt” hydrocarbon reservoirs of the Brazilian coastal basins. In this study, syngenetic and diagenetic aspects of the Ipubi Formation at S...
Análise de fácies e petrografia de uma seção do Membro Crato em Nova Olinda (CE...
Santos, Felipe Holanda dos; Azevedo, Juan Moreira de; Nascimento Junior, Daniel Rodrigues do; Souza, Ana Clara Braga de; Mendes, MarcioThe Crato Member is one of the most important stratigraphic units of the Araripe Basin due to its fossil content, its context analogous to the Brazilian “Pre-Salt Layers”, and its use as covering stone. Facies and petrographic analyses were combined in our study of a section of the Crato Member in Nova Olinda (State of Ceará, Brazil), aiming to investigate its depositional and diagenetic history. Thus, we analy...

Santos, Felipe Holanda dos; Azevedo, Juan Moreira deThe Crato Membre is one of the main stratigraphic units of the Araripe Sedimentary Basin, renowned mainly for the laminated limestone rich in diversified fossils of Albian-Aptian age, worth a title offossil Konservat-Lagerstütte. In the same unit, less famous massive layers of some tabular, decimetres-thick fine sandstones occur interlayered with green shales and limestones, composing an mixed sedimentation. In...
