                         view that the Brazilian Amazonia is located in a tectonically 
                         stable area since the Cretaceous is changing in front of the 
                         increasing documentation of fault reactivations even during the 
                         Holocene. How the sedimentary record has responded to these events 
                         is an issue that remains to be approached with basis on field 
                         data. This work focuses on the stratigraphic correlation of late 
                         Quaternary deposits from eastern Maraj{\'o} Island, with the goal 
                         of demonstrating the role of fault reactivation on the origin and 
                         preservation of these deposits. Despite the location in a stable 
                         platform of a continental passive margin, three studied 
                         stratigraphic units display significant vertical offsets that 
                         define two depocenters that are better explained through tectonic 
                         displacements. This interpretation is reinforced by several 
                         morphostructural features related to faults that occur between the 
                         studied drills. Without the influence of tectonics, sediment 
                         preservation in this characteristically low-lying terrain would 
                         have been negligible. The results of the present work motivate to 
                         look for other tectonically-influenced areas in Amazonia, which 
                         similarly might have acted as sites for sediment accommodation 
                         during the late Quaternary. These sedimentary records have great 
                         potential to be the source of valuable information for 
                         reconstructing Quaternary geological events in Northern Brazil.",
