TL;DR: The authors identified numerous well-preserved elutriation and fluidization structures probably induced by liquefaction in Quaternary gravels and gravelly sediments of braided fluvial channel deposits in the Rio Grande do Norte and Ceara states of Brazil.

TL;DR: An apatite fission track study of crystalline rocks underlying sedimentary basins in northeastern Brazil indicate that crustal blocks that occur on opposite sides of a geological fault experienced different thermal histories.

TL;DR: In this article, the authors identified two beachrock facies in NE Brazil which can be used as reliable sea-level indicators, i.e., Facies (a) represents the lower foreshore and the upper shoreface, being mainly characterized by coarse unsorted sandstones with trough cross-stratification, whereas facies (b) corresponds to sediments deposited on the middle to lower foreshores and is usually characterized by medium to coarse, better sorted sandstones which form seaward-dipping, swash cross beds.

TL;DR: In this paper, the authors present the first data set on the evolution and Holocene infilling of the Potengi River Estuary at the NE Brazilian Continental Margin near the city of Natal.

TL;DR: In this article, the authors describe soft-sediment deformation in gravels and gravelly sediments in Quaternary alluvial deposits of the Potiguar Basin, northeastern Brazil.
