Abstract: The western Nigeria coastline stretches from Badagry in the west (Longitude 5°00’00”E), covering a distance of about 275km. Two major geomorphic coastal units are recognized along this coastline. These are the barrier lagoon coast stretching for almost 200km in the west and the Mahin mud coast which terminates at the north-western flank of the Niger delta. Sediments taken at four different locations spanning this western coastline (Badagry, Lighthouse beach, Lekki and Awoye along the Mahin mud coast) show varying granulometric characteristics. Sediments from Badagry are coarse (0.57phi) to medium (1.31phi) sand which are moderately sorted. Eastwards along the Lighthouse beach sediments are mainly fine and well sorted.
