This study investigates the morpho-sedimentary evidence of two highstands registered and dated during MIS 5 stage by U-series dating in the North of Morocco (Strait of Gibraltar). Bioerosive notch and mixed siliciclastic and carbonate deposits, high energy beaches with algal bioherms, were formed in coastal environments during MIS 5a. A sea-level altitude of +10 m asl was inferred for this substage. The record of MIS 5e-2 substage is less complete, consisting in upper foreshore and storm deposits located some meters above the sea-level (+13-15 m asl). A tectonic uplift rate of ~0.1 mm/yr has been estimated for the last 130 ky. This data is consistent with models of coastal uplifts elaborated for the Gibraltar Strait.
