Paraná Basin

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.

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.

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.
