Seventeen samples of beach sediments were gathered along the littoral between Fnideq and M�diq (NE of Morocco). The mineralogy of the studied samples was investigated through X ray and the obtained geochemical characteristics were used to identify different littoral zones. This way, three main coastal sectors were obtained: the beach of M�diq, which sediments come from the metamorphic complex of Cabo Negro and are characterised by a high content in metals and Potassium; the beaches between Kabila and Marine Smir, that present high levels of carbonates (essentially shell fragments) and high content in Sr; and, the others beaches that contain sediments with intermediate levels of carbonates.
