In this paper we attempt to show the relationship between geodynamics and sequence stratigraphy, emphasizing the effects of regional and local tectonics and their interaction with eustasy. These factors contributed to the final architecture of an area located in the frontal region of the Gibraltar Arc. The Plio-Pleistocene succession located in the Atlantic margin offshore of northern Morocco represents a well-developed Neogene progradational succession. Flexural loading in response to thrusting and extensional collapse of the Gibraltar Arc accretionary wedge, followed by widespread late orogenic uplift are the major mechanisms that controlled accomodation space along the margin. The main stratigraphic units have been subdivided into sequences and systems tracts and reveal nine Pleistocene fourth-order sequences interpreted as glacio-eustatic cycles.

The role of minor structures, such as diapirs, ramp anticlines and normal faults that were active during sedimentation affects stratal patterns but does not modify the presence and timing of sequence boundaries and maximum flooding surfaces. The final stratigraphic signature of the Pleistocene in the study area is the result of the complex interaction of regional tectonics, glacio-eustasy, local tectonics and sedimentary processes.
