%X The well-exposed systems of prograding beach ridges on the Carchuna–Calahonda (Granada) and Campo deDalías–Roquetas (Almería) coastal plains continue offshore as infralittoral prograding wedges (IPW). TheHolocene IPW is a narrow morpho-sedimentary unit up to 2.5 km wide which develops seaward from thelower edge of the shoreface to 15–20 m depth, extending to a well-defined break of slope at water depths of35–40 m. These IPWs have been recognized and studied using very high-resolution seismic profiles (TOPAS)and multibeam data (EM-3000D). In detail they are complex morpho-sedimentary units in which internalstructures are closely linked to the pattern of progradation of the adjacent coastal plains. When longshorecurrents produce significant littoral drift, the IPWs are composed of several minor units arranged in offlap,which accrete parallel or oblique to the main shoreline. Therefore, it is possible to correlate progradationalunits in the coastal plain (H-units, sensu[Goy, J.L., Zazo, C., Dabrio, C.J., 2003.

Besides, it is not realistic to drawconclusions regarding the age of the subunits inside a given IPW without adequate dating, as the number ofsubunits will greatly vary from place to place depending on local factors, magnitude of sea-level oscillations,and sediment supply.
