The Barreiras Formation records continental-to-shallow–water marine sequences deposited during the Paleogene–Neogene periods in the Brazilian continental margin. In northern Rio de Janeiro and southern Espirito Santo states, the Barreiras Formation preserve alluvial depositional system. The sediments were derived from a source located in the hinterland

Abstract We describe the structural and petrophysical evolution of extensional fault zones developed in low porosity, poorly lithified, quartz-dominated sandstones from the Mio-Pliocene continental Barreiras Formation, NE Brazil. We studied eight fault zones developed as sands were lithified. Fault displacement ranges from a few centimetres to ∼50 m.

This work refers to the studies developed in the area of River Catu basin, located in northeastern Brazil. The main objective was to characterize subsurface fault throw within the basin of the River Catu, southern coast of Rio Grande do Norte. The general methodology is the use of electric geophysical methods, particularly electrical resistivity ...

Abstract A coastal environment has been interpreted from 110 cm thick mudstone deposits found at the base of a 10 m immature laterite profile, which forms the modern coastal cliff on Mosqueiro Island in northeastern Para state, northern Brazil. The late Tertiary sediment deposits of the Barreiras Formation are studied by multi-element geochemistry ...
