             abstract = "A large area in northeastern Maraj{\'o} Island, northern Brazil, 
                         has been characterized geomorphologically, applying information 
                         acquired from Landsat imagery. This study was combined with 
                         detailed sedimentologic analysis of continuous cores, which 
                         provided a record of depositional settings developed in this area 
                         through the Holocene. The results revealed well-preserved, 
                         meandering to anastomosed drainage networks of wide palaeochannels 
                         that were superimposed by a narrower palaeochannel system. In both 
                         cases, the sedimentary record consists of sands, heterolithic 
                         deposits and muds, locally rich in plant debris. The strata are 
                         organized into fining upward successions that reach approximately 
                         18 m thick in the wide channels and 4 m thick in the narrow 
                         channels. Sedimentary features suggestive of a coastal location 
                         for the wider palaeochannels and reworking of sediments by tidal 
                         currents include the prevalence of well to moderately sorted, 
                         rounded to subrounded, fine- to medium-grained sands displaying 
                         foreset packages separated by mud couplets, suggestive of tidal 
                         cycles. The data presented herein point to a rise in relative sea 
                         level reaching the Lake Arari area during the early to late/mid 
                         Holocene. This event was followed by a relative sea level drop. 
                         Tectonics seem to have contributed to an overall lowering in 
                         relative sea level in the study area since the mid-Holocene, which 
                         does not follow the same pattern recorded in other areas along the 
                         northern Brazilian coast.",
