Abstract
Tectonic study of a passive margin necessitates distinction between st ructures linked to the initial stretching of the crust and gravitation al structures; In the Gulf of Lions, initial extension in the Oligocen e to Early Aquitanian has produced an asymmetric system of horsts and grabens. Major faults, plunging southeast, are inherited from Late-Her cynian or Mesozoic faults and from Eocene thrusts. Gravitational struc tures are either early structures following the rifting event or late structures linked to thermal subsidence.
