                         incompletely understood, despite their significance for 
                         reconstructing the history of Late Pleistocene-Holocene sea-level 
                         changes in this region and the potential to advance in the 
                         knowledge of wave-influenced deltas. Among them, the Doce River 
                         delta is the most expressive, given its larger geographic 
                         extension. The present work shows that this is a wave-influenced 
                         delta that evolved within the context of Late Pleistocene-Holocene 
                         sea-level fluctuations, rather than a mid-Holocene lagoonal delta 
                         as proposed elsewhere. The delta had an initial progradation at an 
                         OSL age of 132.7 (+/- 9.1) ka after the Marine Isotope Stage (MIS) 
                         5e, which was followed by major progradation between 45,775-49,391 
                         and 29,678-29,226 cal yr BP. Beach ridges/spits formed during 
                         these phases were in part destroyed during an ensuing 
                         transgression between 8161-7933 and 4974-4850 cal yr BP. The 
                         central delta remained dominated by fluvial processes, which kept 
                         pace with the rising sea level due to relatively high rainfall in 
                         the Doce River drainage basin. The Doce River delta started to 
                         grow again after the late-Holocene transgression, a process still 
                         on-going at the present time. During this evolution, the Doce 
                         River was deflected northward and then southward, a process that 
                         did not result in any significant facies change when the updrift 
                         and downdrift sides of the river's mouth are compared. Such a 
                         pattern is in disagreement with previously proposed asymmetry 
                         index models for wave-influenced deltas, which predict an uneven 
                         distribution of sandy- or muddy-rich deposits in the updrift and 
                         downdrift sides of the river's mouth, respectively. Several other 
                         deltas along the Brazilian coast also display facies configuration 
                         similar to the Doce River delta or have patterns opposed to those 
                         proposed by the asymmetry index models. Based on these analogs, it 
                         can be stated that the geometries and fades patterns of 
                         wave-dominated deltas are not determined simply by the interplay 
                         of fluvial and marine processes. Instead, they can be strongly 
                         influenced by the fluvial influx, sea-level changes and/or 
                         tectonic reactivations, as it appears to be the case of Brazilian 
                         wave-influenced deltas, including the Doce River delta. Such a 
                         conclusion calls for a word of caution when applying 
                         processes-based facies models to reconstruct wave-influenced 
                         deltas in the sedimentary record.",
