A complex history of extension, subduction and collision in west Gondwana: Clues from the Riacho do Pontal orogen, Borborema Province (NE Brazil)
Abstract: The geodynamic understanding of the Riacho do Pontal Orogen, in the Borborema Province, NE-Brazil, has progressed substantially in the last decade, mainly from geochemical and isotopic studies.
Chemical and elementary characterization of Spongiophyton nanum: Understanding the phylogeny, paleoenvironment, and fossilization processes of an enigmatic flora
The record of thalloid macrofossils in the North-Northwest region of the Paraná Basin is less studied compared to that of invertebrate paleofauna in the same area. Consequently, the lack of important information regarding the niches occupied by thalloid embryophytes during early land colonization in this coastal paleoenvironment is evident.
Depth-variant pore type modeling in a pre-salt carbonate field offshore Brazil
Brazilian pre-salt carbonates encompass more than 70% of the total oil and gas produced in the country nowadays and yet, present several challenges such as heterogeneous composition in mineralogy with the presence of Mg-clays, a complex pore network and diagenetic processes, e.g., dolomitization, silicification and cementation. Rock physics provides a powerful route to understand the elastic behavior of rocks by connecting geology and geophysics. It is known that pore type determination is crucial to understand this behavior.
Electrofacies definition and zonation of the lower cretaceous Barra Velha formation carbonate reservoir in the pre-salt sequence of the Santos basin, se Brazil
Lower Cretaceous carbonates in the pre-salt succession in the Santos Basin, eastern Brazil, are highly heterogeneous in terms of their reservoir characteristics as a result of depositional and diagenetic factors. Electrofacies have widely been used for reservoir zonation and, when allied with computer-based methods such as neural networks, may help with the study of such complex reservoir rocks and with the identification of high-quality reservoir zones.
Escola de Campo de Hidrogeologia
A Escola de Campo de Hidrogeologia atende as atividades didáticas de disciplinas de graduação, especialmente GE-805 Hidrogeologia e de pós-graduação, especialmente GA-117 Gestão de Recursos Hídricos Subterrâneos, e as atividades didáticas do curso de extensão denominado Avaliação Geoambiental, oferecido pela Extecamp
Estudos paleoambientais e ambientais
O grupo de pesquisa visa realizar estudos integrados no sentido de desenvolver modelos que auxiliem na compreensão do meio ambiente, sua dinâmica relacionada a evolução às biotas terrestres e sua interação com o meio físico. Além disso este grupo pretende entender as transformações que ocorrem com a interferência antrópica.
