dc.description.abstractThis research presents the palynostratigraphy of organic-rich shales from the Irati and the Corumbatai formations, Parana Basin (PB), Southeastern Brazil, as part of an unconventional hydrocarbon source rock and CO2 reservoir assessment study. Thirty-four samples from the Corumbatai Formation and the Assistencia Member of the Irati Formation were collected in the states of Goias (northern border of the PB), Sao Paulo and Parana (eastern and southern border of the PB, respectively). The acquired data allowed to establish a comprehensive palynostratigraphic study across the basin where a total of 18 pollen genera (34 pollen species), seven spore genera, four microplankton genera (1 species), and Chlorophyceae algae species where identified. The palynostratigraphic analysis also reveals a clear dominance of bisaccate pollen grains such as Corisaccites alutas, Lueckisporites virkkiae, and Weylandites lucifer. The Lueckisporites virkkiae zone was identified in the upper part of the Irati Formation (Assistencia Member) and the lowermost part of the Corumbatai Formation, indicating a Kungurian to Roadian age for this part of the succession. Differences in the Guttulapollenites hannonicus and Tornopollenites toreutos biostratigraphic ranges, recovered in the Corumbatai Formation, suggest an earlier development of these species in the Parana Basin during the middle Permian. Therefore, to evaluate the differences in the first occurrences of key species within the Parana Basin, a close palynostratigraphic correlation between the main Guadalupian-Lopingian South American Gondwana basins is tentatively established.
