SUMMARY:

Parabolic dunes occur usually in coastal environments of tropical zones, and consist an important role in the ecological succession of coastal fauna and flora, composing habitat for certain species. A simple model for parabolic dunes internal strata and its correlation with geomorphologic features is proposed. Ground Penetrating Radar (GPR) and altimetric data were acquired in crossline and inline directions in two dune fields in northeast Brazil: Rio do Fogo/RN and São Bento do Norte/RN. PETREL environment was used for the 2D data interpretation, with geophysical attributes application. Five radar facies were interpreted and delimitation of four bounding surfaces was seen, in the hierarchy order: deflation, inundation, superposition, and reactivation. A conceptual model of parabolic dunes is proposed for depositional lobe, trailing arms, back ridges, trailing ridges, and deflation basin.
