Geoquímica de los sedimentos de playas entre Fnideq y M’diq (Tetuán, NE de Marruecos)

Abstract

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
