Palynological insights into the Eocene-Oligocene biostratigraphy , palaeoenviro...
Pereira, Zélia; Silva Mendes, Márcia Cristina; Rodrigues, Cristina F.A.; Nsungani, P.C.ABSTRACT: New biostratigraphic and palaeoenvironmental data from Cabo de Sao Bras in the Kwanza Basin reveal over 40 m of marine sediments (Cunga and Quifangondo formations) spanning the Eocene-Oligocene transition. Wellpreserved dinoflagellate cysts within these sediments provide precise age determinations and palaeoenvironmental insights. The Cunga Formation, ranging from the late Eocene to the Oligocene, is ...

Mendes, Márcia; Pereira, Zélia; Rodrigues, Cristina F.A.; Nsungani, Nsungani, P.C.ABSTRACT: A palynostratigraphic study of the upper Cunga and lower Quifangondo deposits in the Cabo de São Brás section, Kwanza Basin, Angola, has revealed a new pollen named Syncolpraedapollis angolensis nov. gen. sp. nov. This finding was part of a wider survey in the upper Cunga and lower Quifangondo deposits of the Cabo de São Brás section, Kwanza Basin, Angola, covering the latest Eocene to the latest Olig...

Palynology of the Albian–Turonian sediments from the Sumbe region, Kwanza Basin...
Rodrigues, Cristina F.A.; Mendes, Márcia; Pereira, Zélia; Nsungani, P.C.; Fernandes, Paulo; Duarte, L. V.; Chitangueleca, Belarmino; Sebastião, LumenABSTRACT: Palynological investigations in the Sumbe region of the Kwanza Basin, Angola, have identified Albian to Turonian assemblages in four sections of the Quissonde Facies of the Mucanzo, Cabo Ledo, and Itombe formations. These studies aimed to determine their biostratigraphic ages and infer paleoenvironmental, paleoclimatic, and paleogeographic models. The presence of Odontochitina costata, Palaeohystricho...

Rocha, Rocha, H.V.; Sant'Anna, L.G.; Rodrigues, Cristina F.A.; Mendes, Márcia; Pereira, Zélia; Lopes, Gilda; Fernandes, Paulo; Pereira, EgbertoABSTRACT: Mineralogical assemblages and organofacies are important sources of information to recover the paleoenvironmental and thermal histories of shale deposits. In this study, a detailed qualitative and quantitative characterization of the Permian Irati Formation (Assistência Member) shale is based on mineralogical (XRD and SEM-EDS) and organic components (TOC, Rock-Eval pyrolysis, organofacies, TAI, fluore...
