English abstract The young Messinian salt basin offshore the Gulf of Lions comprises a shallow decollement layer (maximum of 3.6 km deep) that allows the seismic imaging of the subsalt relief and the correlation between the shape of subsalt relief and gravity-driven structures. The subsalt relief reveals a variable morphology below the salt layer, characterized by both convex and concave shapes, indicating the
Portuguese abstract A bacia evaporıtica Messiniana do Golfo de Lion constitui um nıvel basal movel bastante raso ( 3.6 km de profundidade), o que facilita o imageamento sısmico da superfıcie de decollement e a correlac¸ao entre tipos de estruturas gravitacionais e a forma do relevo subsalıfero. O relevo subsal revela morfologias convexas e concavas, sugerindo direcoes radiais regionais de fluxo gravitacional. O deslizamento radial e ainda indicado pelas variacoes de espessura da camada de sal. Enquanto zonas de superespessamento do sal recobrem regioes concavas do relevo subsalıfero, e indicam padrao de deslizamento convergente
