Abstract
Analysis of bathymetric and seismic reflection data allow us to characterize the processes and structures that generate seafloor morphological features in the lower continental slope and the transition to the abyssal plain of the Betic-Rif Margin. Several differences can be stablished in the lower slope and the transition to the Horseshoe and Sena Abyssal Plains. The lower slope in the Horseshoe sector shows an upper convex - lower concave profile and the transition to the abyssal plain is marked by a scarp related to the activity of a main NE-SW reverse fault. Whereas in the Sena sector the lower slope appears as a convex profile and the region boundary with the abyssal plain is determined by the position of the external front of the Allochthonous Betic-Rif Units.
