LABAP Basin Analysis Research Lab
The Paraná Basin is one of the largest basins in Brazil. Its more than 7 km thick succession ranges from the Ordovician to the early Cretaceous and covers the entire spectrum of continental to deep marine depositional environments.
Superb exposure of delta-front sandstones in the early Permian Rio Bonito Formation. The cliff is up to 30 m high.
Swaley cross-stratified, shallow marine sandstones of the Palermo Formation (early Permian) in Rio Grande do Sul state.
Bedding-plane exposure of wave ripples in early Permian postglacial strata.
Coarse-grained subaqueous deposits in a Carboniferous delta-slope setting. These facies are interpreted as the products of flood-generated hyperpycnal flows.
Normal faults in Devonian siltstones of the Paraná Basin in the Ponta Grossa arch axial zone
Soft-sediment deformation in late Jurassic eolian-dune sandstones.
Fluvial terminal-splay and eolian deposits of the Rio do Rasto Formation (late Permian) in the Serra do Espigão section.
Typical Cerrado landscape in central-western Brazil. Carboniferous rocks of the Aquidauana Formation in the background.
North side of Serra do Rio do Rastro from Alfredo Wagner; Permian and Mesozoic continental deposits covered by lavas of the Paraná-Etendeka LIP. Gigantic eolian cross-strata are visible in the center of the image.
