RESUMO:

The eastern coast of Rio Grande do Norte presents a more humid climate relative to its northern portion, and its diverse wind deposits occur as parabolic dunes and their associated features, as well as blowout dunes. This work aims to improve the understanding of the migration and evolution of the wind dunes in this region, analyzing and comparing the external morphology with the internal geometry of these eolic deposits. For this, 13 GPR profiles were realized in the Rio do Fogo / RN Wind Park, where five radarfacies were identified, based on shape, dive, relationship and continuity of reflections, as well as their external geometry. Limiting surfaces have also been identified, such as Surface of Deflation, Surface of Interdune, Surface of Superposition and Surface of Reactivation. In addition, the paleocurrent direction of the deposits is similar to the current direction of the main winds, and parabolic dune coalescence events were identified.
