Ciclos e seqüências deposicionais das formações Rio da Batateira e Santana (Andar Alagoas), Bacia do Araripe, Brasil
(2006-12-01)
The Rio da Batateira e Santana formations, the latter with Crato, Ipubi and Romualdo members (Alagoas Stage, Aptian), were studied in four cored and logged wells from the eastern portion of Araripe Basin, Northeastern ...

The transgressive-regressive cycle of the Romualdo Formation (Araripe Basin): Sedimentary archive of the Early Cretaceous marine ingression in the interior of Northeast Brazil
(2017-08-15)
Geologic events related to the opening of the South Atlantic Ocean deeply influenced the sedimentary record of the Araripe Basin. As consequence, upper stratigraphic units of the basin record a marine ingression in ...
Caracterização estratigráfica e faciológico-diagenética da Formação Açu/Unidade Açu-4, Mesocenomaniano - Eoturoniano da Bacia Potiguar
(Universidade Estadual Paulista (Unesp), 2013-10-22)
Main oil accumulations in the Açu Formation (Albian to Early Turonian) occur along two hinge lines which are boundaries of the Potiguar rift. For this work were chosen four fields located in the Areia Branca hinge: Baixa ...
Climatically versus eustatically controlled, sediment-supply-driven cycles: Carbonate-siliciclastic, high-frequency sequences in the valanginian of the Neuqueń Basin (Argentina)
(Society for Sedimentary Geology, 2016-04)
Carbonate–siliciclastic high-frequency sequences are formed by reciprocal sedimentation. In siliciclastic-dominated successions, the carbonate-rich interval is typically associated with transgressive conditions and relatively ...
Sedimentary cycles, ammonite diversity and palaeoenvironmental changes in the Upper Cretaceous Marambio Group, Antarctica
(Elsevier, 2012-01)
Cretaceous sedimentary rocks of the James Ross Basin offer a unique Austral record of the transition from mild mid-Turonian–early Campanian to relatively cold Maastrichtian palaeoclimatic conditions. After deposition of ...
