La marge continentale algérienne et le phénomène de subsidence : exemple du Golfe de Bougie

The study of a continuous seismic-reflection profile (Flexotir) carried out in the central part of the Bougie gulf, enabled the identification of a thick sediment series leaning on the continental basement and continuing underneath the abyssal plain. On the one hand, this series contains a formation (D) thought to be a Miocene salt layer, and on the other hand, it keeps the trace of some upheaval and subsidence movements which define the recent tectonic history of the Bougie gulf. No trace of the current compression phenomenon between the Eurasian and African plates could be found.
