Abstract

Coastal regions constitute as important to geomorphological analysis since landforms resulting from complex processes can be found and provide insights into landscape dynamics at different time and space scales. Several early studies offer an overview of the attributes influencing the evolution of the Paraíba do Sul River coastal plain, Rio de Janeiro state, but the identification and characterization of the low marine terraces remain less explored. Nevertheless, different levels of terraces have been mentioned superficially at least since the 20th century as paleo-sea-levels (PSL) records and arousing many discussions. Therefore, the present work identified and characterized different levels of low marine terraces and the associated surficial covers. For this purpose, orbital and non-orbital images, grain-size analysis, and Ground Penetration Radar (GPR) was used. The hypothesis is that the different levels of these marine terraces can provide insights and contribute to the advancement of knowledge about the evolution of the area during the Holocene. The results indicated two levels of these low marine terraces (N1 and N2), whose morphosedimentary aspects of surficial covers suggest morphogenesis and morphodynamic relationships associated with marine transgressions and regressions in the Upper Holocene. Finally, it is expected that the results can contribute to the advancement of studies on coastal dynamics in the region and, mainly, raise discussions on the influence of Holocene climate pulses in the geomorphological dynamics of coastal regions.
