The Furnas/Ponta Grossa contact and the age of the lowermost Ponta Grossa Formation in the Apucarana Sub-Basin (Paraná Basin, Brazil): integrated palynological age determination

Abstract: Rev. bras. paleontol. 13 (2) ABSTRACT -The Furnas/Ponta Grossa Formation contact was until recently considered gradational or abrupt and of a Lochkovian to Pragian age in the Apucarana Sub-basin (Paraná Basin, south Brazil). Based on sedimentology and palynomorph evidence a hiatus has been revealed between the Furnas Formation and the overlying Ponta Grossa Formation. The boundary between the topmost Furnas sandstones and the lowermost Ponta Grossa fine-grained sandstones constitutes a transgressive ravinement… Show more

“…Gigadiscina collis (= Orbiculoidea collis sensu: Clarke, 1913;Lange, 1954;Melo, 1988;Boucot et al, 2001) has been recorded in the Paraná and Parecis basins up to now, whereas Rugadiscina is found only in the Paraná Basin. Based on the field data and the recent relative dating of the outcrops (see Grahn et al, 2010Grahn et al, , 2013Bosetti et al, 2011Bosetti et al, , 2012, it was possible to determine the discinoid stratigraphic distribution during the Devonian.…”

“…No entanto, a relação de contato entre as formações Furnas e Ponta Grossa é controversa, sendo a mesma caracterizada de forma distinta por diferentes autores. Recentemente, Grahn et al (2010a) e Grahn et al (2010b) apresentaram uma discussão detalhada sobre essa relação de contato nas sub-bacias de Apucarana e de Alto Garças.…”

“…More recent and precise palynological dating has made it possible to reconstruct the Devonian paleogeography of the Brazilian intracratonic basins (Melo & Loboziak, 2003;Grahn & Melo, 2003Grahn et al, , 2006Grahn et al, , 2010aGrahn et al, ,b, 2013. Based on these data the connections between the basins can be studied in more detail ( Figure 1A).…”
