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 palynomorph evidence hiatus has been revealed between Furnas overlying Ponta Formation.The boundary topmost sandstones lowermost fine-grained constitutes transgressive ravinement surface generated during latest -early Emsian transgression.The corresponds maximum ca. 4 Ma.A similar gap is...
A long-lived marine seaway between the Parnaíba and Paraná basins occurred during a global transgression Brazilian intracratonic (except for Solimões Basin) in latest Eifelian/earliest Givetian (Middle Devonian).As result of this catastrophic event (KAČÁK) combination with immigration warm water Appalachian Old World faunas contributed to collapse Malvinokaffric Realm Basin.In Alto Garҫas Apucarana sub-basins, is notable early an impoverished shelly fauna following KAČÁK post-extinction...
New palynomorph data from the Paraná Basin, south Brazil, suggests a discontinuous sedimentation during Lower Devonian. A comparison is made with coeval beds in Argentina, Bolivia and other intracratonic basins Brazil. The Lochkovian/Pragian boundary best developed distinguished by first appearance of Ramochitina magnifica Lange 1967, which succeeds characteristic late Lochkovian chitinozoan species underlying strata (e.g. Angochitina filosa Eisenack 1959, Cingulochitina ervensis Paris 1979,...
The global anoxic event in the Frasnian is well characterized Paraná Basin, upper portion of Ponta Grossa Formation, by dark carbonaceous shales rich organic matter. These are found a section Formation Meso and Neo-Devonian age, where correspond to signature Givetian-Frasnian transition- and, also, progressive drowning Devonian sequence basin. Through geochemical biostratigraphic data obtained from mentioned above, it was possible recognize flood surfaces maximum flooding surface basin that...
RESUMO -A partir das assembléias de miósporos e quitinozoários identificadas nos furos sondagem 269-R1 269-R2, foi possível realizar um biozoneamento detalhado, para o intervalo siluriano da bacia do Paraná na região Paraguai Oriental, envolvendo os sedimentos Grupo Itacurubí.Foram reconhecidas as biozonas lmperfectotriletes chulus-nanus.A biozona lmperfectotriletes, idade neo-aeroniana/
The northeastern region of the state Paraná, Brazil, is still little known in its paleontological and stratigraphic aspects. This work focused on Devonian outcrops located Arapoti Piraí do Sul aimed at recognition sedimentary facies definition taphofacies, with intention paleoenvironmental interpretation correlation. Three different were identified, representing shoreface to offshore environments, also three taphofacies defined: T1 characterizes most proximal destructive T2 represents lower...
